Note 1 The BL651 module PIO pins to which UART, I2C, and SPI interfaces are mapped, are those found on the Nordic development board as well as the BL652 development board. You can bring out UART, I2C, and SPI on any pins allowed by Nordic within the user developed application. Note 2 SWD (two-wire interface), pin 5 (SWDIO) and pin 6 (SWDCLK). We recommend that you use SWD (2-wire interface) to handle customer developed BL651 module firmware upgrades. You MUST wire out the SWD (2-wire interface) on your host design (see Figure 4, where four lines should be wired out, namely SWDIO, SWDCLK, GND and VCC). Note 3 Pull the nRESET pin (pin 7) low for a minimum of 100 milliseconds to reset the BL651. Note 4 Not required for BL651 module normal operation. Nordic SDK examples by default assume that the external 32.768 kHz crystal is connected. You must modify the Nordic SDK example to reflect if the external 32.768 kHz crystal is fitted or not. The on-chip 32.768 kHz RC oscillator provides the standard accuracy of 500 ppm, with calibration required at least every eight seconds to stay within 500 ppm. BL651 also allows the option of connecting an external higher accuracy (20 ppm) 32.768 kHz crystal to the BL651 pins SIO_01/XL2 (pin 24) and SIO_00/XL1 (pin 25). This provides higher accuracy protocol timing and helps with radio power consumption in the SYSTEM ON IDLE or SYSTEM OFF modes by reducing the time that the Rx window must be open. 3.3 Electrical Specifications 3.3.1 Absolute Maximum Ratings Absolute maximum ratings for supply voltage and voltages on digital and analogue pins of the module are listed in Table 3. Exceeding these values causes permanent damage.

Note 1 Stay within internal 0.6 V reference voltage with given pre-scaling on AIN pin and do not violate ADC maximum input voltage (for damage) for a given VCC, e.g. If VCC is 3.6V, you can only expose AIN pin to VDD+0.3 V. Note 2 Through customer firmware the resolution (8-bit, 10-bit, or 12-bit mode or oversample 14-bit) and acquisition time is configurable. The sampling frequency is limited by the sum of sampling time and acquisition time. The maximum sampling time is 2us. For acquisition time of 3us the total conversion time is 5us, which makes maximum sampling frequency of 1/5us = 200 kHz. Similarly, if acquisition time of 40us chosen, then the conversion time is 42us and the maximum sampling frequency is 1/42us = 23.8 kHz Note 3 ADC input impedance is estimated mean impedance of the ADC (AIN) pins. www.lairdtech.com/bluetooth 13 Copyright 2018 Laird.

The use of the internal DCDC convertor or LDO is decided by the underlying BLE stack. Note 2 BL651: System ON IDLE current is 1.5 uA typical. System ON IDLE is entered automatically through a command in the customer-developed firmware. In System ON IDLE, all enabled peripherals remain on and may re-awaken the chip. Depending on active peripherals, current consumption ranges from ~1.5 A to 270 uA (when UART is ON). See individual peripherals current consumption data in the Peripheral Block Current Consumption section. Through customers FW development, functionality to detect GPIO change with no current consumption cost, it is possible to close the UART and get to the 1.5uA current consumption regime and still detect incoming data and be woken up so that the UART can be re-opened at expense of losing that first character. The BL651 System ON IDLE current consists of the below nRF52810 blocks:

Note 3 In System OFF, everything is disabled and the only wake-up sources are reset and changes on GPIO on which sense is enabled. The current consumption is ~300 nA typical in BL651. Hardware reset to come out of System OFF. Can come out from System OFF to System ON IDLE through GPIO signal through the reset vector. Note 4 Average current consumption depends on several factors (including Tx power, VCC, accuracy of 32 MHz and 32.768 kHz), all peripherals off (UART OFF after radio event), slave latency of 0 (in a connection). With these factors fixed, the largest variable is the advertising or connection interval set. Advertising Interval range:

20 milliseconds to 10240 milliseconds (10485759.375 mS in BT5.0) in multiples of 0.625 milliseconds. For an advertising event:

The minimum average current consumption is when the advertising interval is large 10240 milliseconds

(10485759.375 mS - in BT5.0) although this may cause long discover times (for the advertising event) by scanners The maximum average current consumption is when the advertising interval is small 20 mS Other factors that are also related to average current consumption include the advertising payload bytes in each advertising packet and whether its continuously advertising or periodically advertising. Connection Interval range (for a peripheral device):

7.5 milliseconds to 4000 milliseconds in multiples of 1.25 milliseconds. For a connection event (for a peripheral device):

The minimum average current consumption is when the connection interval is large 4000 milliseconds The maximum average current consumption is with the shortest connection interval of 7.5 ms; no slave latency. Other factors that are also related to average current consumption include:

Number of packets per connection interval with each packet payload size An inaccurate 32.768 kHz master clock accuracy would increase the average current consumption. 4.2 Peripheral Block Current Consumption The following values are calculated for a typical operating voltage of 3V.

uA The above current consumption is for the given peripheral only; to operate that peripheral requires some other internal blocks which consume base current. This base current is consumed when the UART, SPI, I2C, or ADC is opened (operated). For asynchronous interface like the UART (asynchronous as the other end can communicate at any time), the UART on the BL651 must be kept open (by a command in customers application), resulting in the base current consumption penalty. For a synchronous interface like the I2C or SPI, the interface can be closed and opened only when needed, resulting in current saving (no base current consumption penalty). Theres a similar argument for ADC (open ADC when needed). 5 FUNCTIONAL DESCRIPTION The BL651 BLE (Bluetooth Low Energy) module is a self-contained product and requires only power and a users application to implement full BLE functionality. The integrated, high performance PCB trace antenna combined with the RF and base-

band circuitry provides the BLE wireless link, and any of the GPIO lines provide the OEMs chosen interface connection to the sensors. BL651 module hardware is functionally capable as the nRF52810 chipset used in the module design and Table 12 shows the nRF52810 features list from Nordic Documentation http://infocenter.nordicsemi.com/index.jsp.

System ON IDLE and System OFF modes Open/Close peripherals (UART, SPI, I2C, GPIOs, ADC). Peripherals consume current when open; each peripheral can be individually closed to save power consumption Use of the internal DCDC convertor or LDO is decided by the underlying BLE stack VCC voltage to be read (through the internal ADC) Pin wake-up system from deep sleep Power supply features:

The integrated on-chip 32.768 kHz RC oscillator (500 ppm) provides protocol timing and helps with radio power consumption in the system StandByDoze and Deep Sleep modes by reducing the time that the RX window must be open. To keep the on-chip 32.768 kHz RC oscillator within 500 ppm (which is needed to run the BLE stack) accuracy, the RC oscillator must be calibrated (which takes 16-17 milliseconds) regularly. The default calibration interval is at least eight seconds which is enough to keep within 500 ppm. The calibration interval ranges from 0.25 seconds to 31.75 seconds (in multiples of 0.25 seconds). 5.2.2 Timers Regular Timer There are five built-in timers (regular timers) derived from a single RTC clock; the resolution of the regular timer is 976 microseconds. Tick Timer (Counter) A 31-bit free running counter that increments every (one) millisecond. The resolution of this counter is 488 microseconds. 5.3 Memory The nRF52810 has 192 kBytes Flash and 24 kB RAM. 5.4 Radio Frequency (RF) 24022480 MHz Bluetooth Low Energy radio BT5.0 (1 Mbps and 2 Mbps over-the-air data rate) Tx output power of +4 dBm programmable to -20 dBm in steps of 4 dB and further down -40 dBm Receiver (with integrated channel filters) to achieve maximum sensitivity -96 dBm @ 1 Mbps BLE and 93 dBm @ 2 Mbps BLE.

UART_TX, UART_RX, UART_RTS, and UART_CTS form a conventional asynchronous serial data port with handshaking. The interface is designed to operate correctly when connected to other UART devices such as the 16550A. The signaling levels are nominal 0 V and 3.3 V (tracks VCC) and are inverted with respect to the signaling on an RS232 compliant cable. Two-way hardware flow control is implemented by UART_RTS and UART_CTS. UART_RTS is an output and UART_CTS is an input. Both are active low. www.lairdtech.com/bluetooth 19 Copyright 2018 Laird. All Rights Reserved Americas: +1-800-492-2320 Europe: +44-1628-858-940 Hong Kong: +852 2923 0610 BL651 Series Datasheet These signals operate according to normal industry convention. UART_RX, UART_TX, UART_CTS, UART_RTS are all 3.3 V level logic (tracks VCC). For example, when RX and TX are idle, they sit at 3.3 V. Conversely, for handshaking pins CTS, RTS at 0 V is treated as an assertion. The module communicates with the customer application using the following signals:

Port/TxD of the application sends data to the modules UART_RX signal line Port/RxD of the application receives data from the modules UART_TX signal line BL651 Figure 3: UART signals Note:

The BL651 serial module output is at 3.3V CMOS logic levels (tracks VCC). Level conversion must be added to interface with an RS-232 level compliant interface. Some serial implementations link CTS and RTS to remove the need for handshaking. We do not recommend linking CTS and RTS other than for testing and prototyping. If these pins are linked and the host sends data at the point that the BL651 de-

asserts its RTS signal, then there is significant risk that internal receive buffers will overflow. This could lead to an internal processor crash which would drop the connection and may require a power cycle to reset the module. We recommend that the correct CTS/RTS handshaking protocol be adhered to for proper operation. The BL651 module PIO pins to which the UART interface is mapped are those found on the Nordic development board as well as the BL652 development board. You can bring out UART on any pins allowed by Nordic within the user application.

The module can be a master device (or slave device) that uses terminals SPI_MOSI, SPI_MISO, and SPI_CLK. SPI_CS is implemented using any spare SIO digital output pins to allow for multi-dropping. Each multidrop SPI slave device requires a unique and dedicated SPI_CS line. The SPI interface enables full duplex synchronous communication between devices. It supports a 3-wire (SPI_MOSI, SPI_MISO, SPI_SCK) bi-directional bus with fast data transfers to and from multiple slaves.

The BL651 module PIO pins to which the SPI interface is mapped are those found on the Nordic development board as well as the BL652 development board. You can bring out SPI on any pins allowed by Nordic within the user application. 5.7 I2C Interface The I2C interface is an alternate function on GPIO pins. The two-wire interface can interface a bi-directional wired-OR bus with two lines (SCL, SDA) and has master/slave topology. Data rates of 100 kbps and 400 kbps are supported along with 250 kbps for master only. The interface is capable of clock stretching. An I2C interface allows multiple masters and slaves to communicate over a shared wired-OR type bus consisting of two lines which normally sit at VCC. The BL651 module can only be configured as an I2C master or slave. The SCL is the clock line which is always sourced by the master; and SDA is a bi-directional data line which can be driven by any device on the bus. IMPORTANT:

It is essential to remember that pull-up resistors on both SCL and SDA lines are not provided in the module and MUST be provided external to the module.

The BL651 provides access to 8-channel 8/10/12-bit successive approximation ADC in one-shot mode. This enables sampling up to eight external signals through a front-end MUX.

The PWM output signal has a frequency and duty cycle property. Frequency is adjustable (up to one MHz) and the duty cycle can be set over a range from 0% to 100%

PWM output signal has a frequency and duty cycle property. PWM output is generated using dedicated hardware in the chipset. There is a trade-off between PWM output frequency and resolution. For example:

PWM output frequency of 500 kHz (2 uS) results in resolution of 1:2 PWM output frequency of 100 kHz (10 uS) results in resolution of 1:10 PWM output frequency of 10 kHz (100 uS) results in resolution of 1:100 PWM output frequency of 1 kHz (1000 uS) results in resolution of 1:1000 5.9 nRESET pin Table 17: nRESET pin BL651 Signal Name BL651 Pin Number I/O Comments nRESET 7 I BL651 HW reset (active low).

You MUST wire out the SWD (2-wire interface) on your host design (see Figure 4, where four lines should be wired out, namely SWDIO, SWDCLK, GND and VCC). P0.18 is a trace output (called SWO, Serial Wire Output) and is not necessary for programming the BL651 over the SWD interface. nReset_BLE is not necessary for programming the BL651 over the SWD interface. 5.11 BL651 Wakeup 5.11.1 Waking Up BL651 from Host Wake the BL651 from the host using wake-up pins (any PIO pin). You may configure the BL651s wakeup pins in the customers application to do any of the following:

Wake up when signal is low Wake up when signal is high Wake up when signal changes 5.12 Low Power Modes The BL651 has three power modes: Run (Active), Standby Doze (SYSTEM ON IDLE), and Deep Sleep (SYSTEM OFF). The module wakes from Standby Doze via any interrupt (such as a received character on the UART Rx line). If the module receives a UART character from either the external UART or the radio, it wakes up. Deep sleep is the lowest power mode. Once awakened, the system goes through a system reset. 5.13 Temperature Sensor The on-silicon temperature sensor has a temperature range greater than or equal to the operating temperature of the device with accuracy 5C. Resolution is 0.25C. 5.14 Security/Privacy 5.14.1 AES Encryption/Decryption Exposed via Nordic SDK functions, refer to Nordic documentation. www.lairdtech.com/bluetooth 24 Copyright 2018 Laird.

The BL651 offers a range of functions for generating public/private keypair, calculating a shared secret, as well as generating an authenticated hash. 5.15 Optional External 32.768 kHz Crystal This is not required for normal BL651 module operation. Nordic SDK examples by default assume that he external 32.768 kHz crystal is connected. The customer must modify the Nordic SDK example to reflect whether or not the external 32.768 kHz crystal is fitted. The BL651 uses the on-chip 32.76 kHz RC oscillator (LFCLK) by default (which has an accuracy of 500 ppm); this requires regulator calibration (at least every eight seconds) to within 500 ppm. You can connect an optional external high accuracy (20 ppm) 32.768 kHz crystal to the BL651pins, P0.01/XL2 (pin 24) and P0.00/XL1 (pin 25) to provide improved protocol timing and to help with radio power consumption in the system standby doze/deep sleep modes by reducing the time that the RX window needs to be open. ! compares the current consumption difference between RC and crystal oscillator.

The average current consumed by the calibration depends on the calibration interval and can be calculated using the following formula:

CAL_charge/CAL_interval The lowest calibration interval (0.25 seconds) provides an average current of (DCDC enabled):

7.4uC / 0.25s = 29.6uA To get the 500-ppm accuracy, the BLE stack specification states that a calibration interval of eight seconds is enough. This gives an average current of:

The following are suggestions for your design for the best performance and functionality. Checklist (for Schematic):

VCC pins External power source should be within the operating range, rise time and noise/ripple specification of the BL651. Add decoupling capacitors for filtering the external source. Power-on reset circuitry within BL651 series module incorporates brown-out detector, thus simplifying your power supply design. Upon application of power, the internal power-on reset ensures that the module starts correctly. VCC and coin-cell operation With built-in DCDC (operating range 1.7V to 3.6V), reduces the peak current required from a coin-cell, making it easier to use with coin-cell. AIN (ADC) and GPIO pin IO voltage levels BL651 GPIO voltage levels are at VCC. Ensure input voltage levels into GPIO pins are at VCC also (if VCC source is a battery whose voltage will drop). Ensure ADC pin maximum input voltage for damage is not violated. AIN (ADC) impedance and external voltage divider setup If you need to measure with ADC a voltage higher than 3.6V, you can connect a high impedance voltage divider to lower the voltage to the ADC input pin. SWD We recommend that use SWD (2-wire interface) to handle customer developed BL651 module firmware upgrades. You MUST wire out the JTAG (2-wire interface) on your host design (see Figure 4, where four lines should be wired out, namely SWDIO, SWDCLK, GND and VCC). UART Add connector to allow interfacing with UART via PC (UARTRS232 or UART-USB). Laird recommends flow control to prevent UART data loss. I2C It is essential to remember that pull-up resistors on both I2C_SCL and I2C_SDA lines are not provided in the BL651 module and MUST be provided external to the module as per I2C standard. SPI Implement SPI chip select using any unused GPIO pin within customers application then SPI_CS is controlled from customers application allowing multi-dropping. GPIO pin direction BL651 modules shipped from production are un-programmed. Remember to change the direction GPIO pin (in customer developed application) if that particular pin is wired to a device that expects to be driven by the BL651 GPIO pin configured as an output. Also, these GPIO pins if used as inputs have the internal pull-up or pull-down resistor. To avoid floating inputs which can cause current consumption in low power modes (e.g. System ON IDLE) to drift with time;

customer can enable the PULL-UP or PULL-DOWN through their application. Note:

Internal pull-up, pull down will take current from VCC. nRESET pin (active low) Hardware reset. Wire out to push button or drive by host. By default module is out of reset when power applied to VCC pins. Optional External 32.768kHz crystal www.lairdtech.com/bluetooth 28 Copyright 2018 Laird. All Rights Reserved Americas: +1-800-492-2320 Europe: +44-1628-858-940 Hong Kong: +852 2923 0610 BL651 Series Datasheet If the optional external 32.768kHz crystal is needed then use a crystal that meets specification. Nordic SDK examples by default assume external 32.768kHz crystal is connected. Customer must modify Nordic SDK example to reflect if external 32.768kHz crystal is fitted or not. 6.2 PCB Layout on Host PCB - General Checklist (for PCB):

You MUST locate the BL651 module close to the edge of PCB (mandatory for 453-00005 for on-board PCB trace antenna to radiate properly). Use solid GND plane on inner layer (for best EMC and RF performance). All module GND pins MUST be connected to host PCB GND. Unused PCB area on surface layer can flooded with copper but place GND vias regularly to connect copper flood to Place GND vias as close to module GND pads as possible. inner GND plane. If GND flood copper underside the module then connect with GND vias to inner GND plane. Route traces to avoid noise being picked up on VCC supply and AIN (analogue) and SIO (digital) traces. Ensure no exposed copper is on the underside of the module (refer to Figure 10 land pattern of BL652 development board). 6.3 PCB Layout on Host PCB for 453-00005 6.3.1 Antenna Keep-out on Host PCB The 453-00005 has an integrated PCB trace antenna and its performance is sensitive to host PCB. It is critical to locate the 453-00005 on the edge of the host PCB (or corner) to allow the antenna to radiate properly. Refer to guidelines in the PCB land pattern and antenna keep-out area for 453-00005 section. Some of those guidelines repeated below. Ensure there is no copper in the antenna keep-out area on any layers of the host PCB. Keep all mounting hardware and metal clear of the area to allow proper antenna radiation. For best antenna performance, place the 453-00005 module on the edge of the host PCB, preferably the edge center. The BL651 development board (not commercially available) has the 453-00005 module on the edge of the board

(preferably the edge center). The antenna keep-out area is defined by the BL651 development board which was used for module development and antenna performance evaluation is shown in Figure 7, where the antenna keep-out area is ~4.95mm wide, 25.65 mm long; with PCB dielectric (no copper) height 0.85 mm sitting under the 453-00005 PCB trace antenna. The 453-00005 PCB trace antenna is tuned when 453-00005 module is sitting on development board (host PCB) with size of 120 mm x 93 mm. A different host PCB thickness dielectric will have a small effect on antenna. Host PCB land pattern and antenna keep-out for the BL651 applies when the 453-00005 is placed in the edge of the The antenna-keep-out defined in the Host PCB Land Pattern and Antenna Keep-out for 453-00005 section. host PCB, preferably the edge center.

Note 1 The BL651 module is placed on the edge of the host PCB, preferably edge center of the host PCB. Note 2 Copper cut-away on all layers in the Antenna Keep-out area under 453-00005 on host PCB. 6.3.2 Antenna Keep-out and Proximity to Metal or Plastic Checklist (for metal /plastic enclosure):

Minimum safe distance for metals without seriously compromising the antenna (tuning) is 40 mm top/bottom and 30 mm left or right. Metal close to the 453-00005 PCB trace monopole antenna (bottom, top, left, right, any direction) will have degradation on the antenna performance. The amount of that degradation is entirely system dependent, meaning you must perform some testing with your host application. Any metal closer than 20 mm begins to significantly degrade performance (S11, gain, radiation efficiency). It is best that you test the range with a mock-up (or actual prototype) of the product to assess effects of enclosure height (and materials, whether metal or plastic) and host PCB size (ground plane size). 6.4 External Antenna Integration with 453-00006 Please refer to the regulatory sections for FCC, IC, CE, and Japan for details of use of BL651 (453-00006) with external antennas in each regulatory region. The BL651 family is designed to operate with the following external antennas (with a maximum gain of 2.0 dBi). The required antenna impedance is 50 ohms. See Table 23.

Host PCB Land Pattern and Antenna Keep-out for 453-00005 Notes:

Note 1 Ensure there is no copper in the antenna keep out area on any layers of the host PCB. Also keep all mounting hardware or any metal clear of the area (Refer to 6.3.2) to reduce effects of proximity detuning the antenna and to help antenna radiate properly. Note 2 For the best on-board antenna performance, the module 453-00005 MUST be placed on the edge of the host PCB and preferably in the edge centre of host PCB, the antenna keep out area is extended (see Note 4). Note 3 BL651 development board has 453-00005 placed on the edge of the PCB board (and not in corner) for that the Antenna keep out area is extended down to the corner of the development board, see the PCB Layout on Host PCB for 453-00005 section. This was used for module development and antenna performance evaluation. Note 4 Ensure that there is no exposed copper under the module on the host PCB.

The BL651 module internal BLE chipset IC pins are rated 4 kV (ESD HBM). ESD can find its way through the external JTAG connector (if used on the customers design), if discharge is applied directly. Customer should ensure adequate protection against ESD on their end product design (using the BL651 module) to meet relevant ESD standard (for CE, this is EN301-489). 11.2 EU Declarations of Conformity Manufacturer Products Laird 453-00005, 453-00006 Product Description Bluetooth v5.0 Module Series EU Directives 2014/53/EU Radio Equipment Directive (RED) Reference standards used for presumption of conformity:

Design Name BL651 Series Owner Declaration ID QD ID Link to listing on the SIG website Laird Technologies TBC TBC TBC It is a mandatory requirement of the Bluetooth Special Interest Group (SIG) that every product implementing Bluetooth technology has a Declaration ID. Every Bluetooth design is required to go through the qualification process, even when referencing a Bluetooth Design that already has its own Declaration ID. The Qualification Process requires each company to registered as a member of the Bluetooth SIG www.bluetooth.org The following link provides a link to the Bluetooth Registration page: https://www.bluetooth.org/login/register/

For each Bluetooth Design, it is necessary to purchase a Declaration ID. This can be done before starting the new qualification, either through invoicing or credit card payment. The fees for the Declaration ID will depend on your membership status, please refer to the following webpage:

https://www.bluetooth.org/en-us/test-qualification/qualification-overview/fees For a detailed procedure of how to obtain a new Declaration ID for your design, please refer to the following SIG document:

https://www.bluetooth.org/DocMan/handlers/DownloadDoc.ashx?doc_id=283698&vId=317486 13.2 Qualification Steps When Referencing a Laird End Product Design To start a listing, go to: https://www.bluetooth.org/tpg/QLI_SDoc.cfm In step 1, select the option, Reference a Qualified Design and enter TBC in the End Product table entry. You can then select your pre-paid Declaration ID from the drop down menu or go to the Purchase Declaration ID page, (please note that unless the Declaration ID is pre-paid or purchased with a credit card, it will not be possible to proceed until the SIG invoice is paid. Once all the relevant sections of step 1 are finished, complete steps 2, 3, and 4 as described in the help document. Your new Design will be listed on the SIG website and you can print your Certificate and DoC. For further information, please refer to the following training material:

13.3 Qualification Steps When Deviating from a Laird End Product Design If you wish to deviate from the standard End Product design listed under D031950, the qualification process follows the Traditional Project route, creating a new design. When creating a new design, it is necessary to complete the full qualification listing process and also maintain a compliance folder for the new design. The BL651 design under D031950 incorporates the following components:

Please check with Nordic to make sure these software components are compatible with the nRF52 hardware (D029601). If your design is based on un-modified BL651 hardware it is possible use the following process;

2. Reference the existing RF-PHY test report from the BL651 listing. 3. Combine the relevant Nordic Link Layer (LL) check QDID with Nordic. 4. Combine in a Host Component (covering L2CAP, GAP, ATT, GATT, SM) - check QDID with Nordic. 5. Test any standard SIG profiles that are supported in the design (customs profiles are exempt). End Product Laird RF-PHY Nordic LL Host Layers Profiles Figure 18: Scope of the qualification for an End Product Design The first step is to generate a project on the TPG (Test Plan Generator) system. This determines which test cases apply to demonstrate compliance with the Bluetooth Test Specifications. If you are combining pre-tested and qualified components in your design and they are within their three-year listing period, you are not required to re-test those layers covered by these components. If the design incorporates any standard SIG LE profiles (such as Heart Rate Profile), it is necessary to test these profiles using PTS or other tools where permitted; the results are added to the compliance folder. You are required to upload your test declaration and test reports (where applicable) and then complete the final listing steps on the SIG website. Remember to purchase your Declaration ID before you start the qualification process, as its impossible to complete the listing without it. 14 ADDITIONAL ASSISTANCE Please contact your local sales representative or our support team for further assistance:
