During the layout of the board, please make sure the area right below the antenna is completely clear, as shown in the following figure. The red part is the users backplane area or the copper-clad area, the grey part is the clear area of the antenna of the users backplane, and the boundary point of the clear area is the upper edge of the shielding cover. Make sure there is no any metal in 360 degrees around the antenna; otherwise, the radiation efficiency of the antenna will be affected, and the communication distance will be greatly affected. Drawing 2-3 Description of Clear Area of Antenna 3. Basic Operation The module is installed on the users product. Since the module is equipped with MCU, it can be Page 7 of 15 Leader in IOT Embedded Solution directly operated via the built-in MCU control register and the transceiver buffer, which can complete the receiving function of wireless data. The read-write operation timing sequence of the module register is shown in the drawing. For more operation information, please refer to the latest data manual CC2510. Drawing 3-1 SPI Timing Sequence 4. Frequently Asked Questions 4.1 The communications cannot be made if the module is at close range To verify whether the sending and receiving configurations are matching and the communications cannot be made if the configurations are different. The voltage is abnormal; and the transmission will be abnormal if the voltage is too low. The battery is low; and the transmission will be abnormal if the voltage is lowered due to the low volume battery. The RF signal does not reach the antenna or circuit soldering occurs error if antenna welding is abnormal. 4.2 Module communication distance is not enough The power transmitted is small due to bad antenna impedance matching. Objects such as metal around the antenna or the metal inside the module may cause serious signal attenuation. Any other interference signals in the test environment may cause the module to communicate close. Page 8 of 15 Leader in IOT Embedded Solution Insufficient power supply will make the modules transmit power abnormal. Harsh test environment will make signal attenuation greater. When the module communicates with other end after passing through the wall, the wall will have a great impact on signal attenuation. The signal will be attenuated greatly when most of signals are passing through the wall. If the module is too close to the ground, resulting in poor communication due to being absorbed and reflected. 5. Notation of Annexes 1. Recommended to use DC stabilized power supply to power for the module. The power ripple coefficient should be as close as possible and the module needs to be reliably grounded. Please be noted that the positive and negative poles of power supply shall be correctly connected. The module may be permanently damaged if connected reversely. 2. Prohibited to have any metal objects around the module antenna. Otherwise, the communication distance may be seriously affected. Page 9 of 15 Leader in IOT Embedded Solution 6.

,Home wireless security alarm system. The input voltage to the module should be nominally 2.0~3.6 VDC ,typical value 3.3VDC and the ambient temperature of the module should not exceed 85. This module using only one kind of antennas with maximum gain is 0.5dBi .Other antenna arrangement is not covered by this certification. The antenna is not field replaceable. If the antenna needs to be changed, the certification should be re-applied. 2.4 Limited module procedures Not applicable 2.5 Trace antenna designs Not applicable 2.6 RF exposure considerations This 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& your body. If the device built into a host as a portable usage, the additional RF exposure evaluation may be required as specified by 2.1093. 2.7 Antennas Module only contains one PCB antenna. No additional external connectors. 2.8 Label and compliance information The outside of final products that contains this module device must display a label referring to the enclosed module. This exterior label can use wording such as: Contains Transmitter Module FCC ID: 2AOFDLSD4RF043610D0 ,or Contains FCC ID: 2AOFDLSD4RF043610D0 , Any similar wording that expresses the same meaning may be used. Page 12 of 15 Leader in IOT Embedded Solution 2.9 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 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. Below are steps for TX verification RfTest();
// RF parameter configuration STX();
//Set RF to send mode SIDLE()
// Set RF to IDLE mode ,stop sending data 2.10 Additional testing, Part 15 subpart B disclaimer The final host / module combination need to be evaluated against the FCC Part 15B Page 13 of 15 Leader in IOT Embedded Solution criteria for unintentional radiators in order 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 rules, including the transmitter operation and should refer to guidance in KDB 996369. Frequency spectrum to be investigated For host products with 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. Operating the host product 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. In certain conditions it might be appropriate to use a technology-specific call box
(test set) where accessory devices or drivers are not available. When testing for emissions from the unintentional radiator, the transmitter shall be placed in the receive mode or idle mode, if possible. If receive mode only is not possible then, the radio shall be passive (preferred) and/or active scanning. 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 WLAN 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 a file or streaming some media content.
