- The product shall be stored in non-corrosive gas (CL2, NH3, SO2, NOx, etc.).

- Any excess mechanical shock including, but not limited to, sticking the packing materials by sharp object and dropping the product, shall not be applied in order not to damage the packing materials. This product is applicable to MSL3 (Based on IPC/JEDEC J-STD-020)

- After the packing opened, the product shall be stored at <30 C / <60 %RH and the product shall be used within 168 hours.

- When the color of the indicator in the packing changed, the product shall be baked before soldering. Baking condition: 125 +5/-0 C, 24 hours, 1 time The products shall be baked on the heat-resistant tray because the material (Base Tape, Reel Tape and Cover Tape) are not heat-resistant. 12.2. Handling Conditions Be careful in handling or transporting products because excessive stress or mechanical shock may break products. Handle with care if products may have cracks or damages on their terminals, the characteristics of products may change. Do not touch products with bear hands that may result in poor solderability. 12.3. Standard PCB Design (Land Pattern and Dimensions) All the ground terminals should be connected to the ground patterns. Furthermore, the ground pattern should be provided between IN and OUT terminals. Please refer to the specifications for the standard land dimensions. The recommended land pattern and dimensions is as Murata's standard. The characteristics of products may vary depending on the pattern drawing method, grounding method, land dimensions, land forming method of the NC terminals and the PCB material and thickness. Therefore, be sure to verify the characteristics in the actual set. When using non-standard lands, contact Murata beforehand. 12.4. Notice for Chip Placer :

When placing products on the PCB, products may be stressed and broken by uneven forces from a worn-out chucking locating claw or a suction nozzle. To prevent products from damages, be sure to follow the specifications for the maintenance of the chip placer being used. For the positioning of products on the PCB, be aware that mechanical chucking may damage products. 12.5. Soldering Conditions The recommendation conditions of soldering are as in the following figure. When products are immersed in solvent after mounting, pay special attention to maintain the temperature difference within 100 C. Soldering must be carried out by the above mentioned conditions to prevent products from damage. Set up the highest temperature of reflow within 260 C. Contact Murata before use if concerning other soldering conditions.

It complies to the requirements of FCC part 15C, section 15.205, 15.207, 15.209, and 15.247 rules. 2. The specific operational use conditions This module can be used in IoT devices. The input voltage to the module is nominally 3.3VDC. The operational ambient temperature of the module is -40 to 85 degree C. 3. Limited module procedures N/A. 4. Trace antenna design Please contact your Murata sales to get more details. 5. RF exposure considerations The equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with minimum distance 20cm between the radiator and your body. If the equipment built into a host as a portable usage, the additional RF exposure evaluation may be required as specified by 2.1093.

PCB pattern Antenna with peak gain 1.0dBi. Flexible Antenna (Molex: 2111400100) with peak gain 1.0dBi. 7. Label and compliance information An exterior label on OEMs end product can use wording such as the following: Contains Transmitter Module FCC ID: VPYLB1SJ or Contains FCC ID: VPYLB1SJ. In addition, the following statements shall also appear on the surface of the product. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. 8. Information on test modes and additional testing requirements a)The modular transmitter has been fully tested by the module grantee on the required number of channels, modulation types, and modes, it should not be necessary for the host installer to re-test all the available transmitter modes or settings. It is recommended that the host product manufacturer, installing the modular transmitter, perform some investigative measurements to confirm that the resulting composite system does not exceed the spurious emissions limits or band edge limits (e.g., where a different antenna may be causing additional emissions). b)The testing should check for emissions that may occur due to the intermixing of emissions with the other transmitters, digital circuitry, or due to the physical properties of the host product

(enclosure). This investigation is especially important when integrating multiple modular transmitters where the certification is based on testing each of them in a stand-alone configuration. It is important to note that host product manufacturers should not assume that because the modular transmitter is certified that they do not have any responsibility for final product compliance. c)If the investigation indicates a compliance concern the host product manufacturer is obligated to mitigate the issue. Host products using a modular transmitter are subject to all the applicable individual technical rules as well as to the general conditions of operation in Sections 15.5, 15.15, and 15.29 to not cause interference. The operator of the host product will be obligated to stop operating the device until the interference has been corrected. 9. Additional testing, Part 15B disclaimer The final host/module combination needs to be evaluated against the FCC Part 15B criteria for unintentional radiators to be properly authorized for operation as a Part 15 digital device. The host integrator installing this module into their product must ensure that the final composite product complies with the FCC requirements by a technical assessment or evaluation to the FCC

Preliminary & Confidential Murata Manufacturing Co., Ltd. Preliminary Specification Number : SP-1SJ-295 24 / 24 rules, including the transmitter operation and should refer to guidance in KDB 996369. For host products with the certified modular transmitter, the frequency range of investigation of the composite system is specified by rule in Sections 15.33(a)(1) through (a)(3), or the range applicable to the digital device, as shown in Section 15.33(b)(1), whichever is the higher frequency range of investigation. When testing the host product, all the transmitters must be operating. The transmitters can be enabled by using publicly available drivers and turned on, so the transmitters are active. When testing for emissions from the unintentional radiator, the transmitter shall be placed in the receive mode or idle mode, if possible. In these cases, this would need to enable activity on the communication BUS (i.e., PCIe, SDIO, USB) to ensure the unintentional radiator circuitry is enabled. Testing laboratories may need to add attenuation or filters depending on the signal strength of any active beacons (if applicable) from the enabled radio(s). See ANSI C63.4, ANSI C63.10 and ANSI C63.26 for further general testing details. The product under test is set into a link/association with a partnering device, as per the normal intended use of the product. To ease testing, the product under test is set to transmit at a high duty cycle, such as by sending continuous packets. Preliminary & Confidential
