The module shall be only used with the internal antenna(s) that has been originally tested and certified with this module. As long as 3 conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.). 2.4Because the module has no shielding cover,it is a restricted module. 2.5 Not applicable. The module has its own antenna, and doesn’t need a trace antenna etc. 2.6RF exposure considerations This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. This equipment should be installed and operated with a minimum distance of 20cm between the radiator & your body. This transmitter must not be co-located or operating in conjunction with any other antenna or transmitter. 2.7Antennas Antenna Type:Rod antenna Antenna Gain(Peak): 5dbi 2.8The final end product must be labeled in a visible area with the following: “Contain FCC ID: 2A8XG-UDK52”. 2.9Operation Frequency: 2405-2480MHz Number of Channel: 16 Channels Modulation: O-QPSK Host manufacturer must perfom test of radiated & conducted emission and spurious emission,etc according to the actual test modes for a stand-alone modular transmitter in a host. Only when all the test results of test modes comply with FCC requirements, then the end product can be sold legally. 2.10Additional testing Part15SubpartB disclaimer The grantee should include a statement that the modular transmitter is only FCC authorized forthe specific rule parts (i.e.,FCC transmitter rules )listedonthegrant, and that the host productmanufacturer is responsible for compliance to any other FCC rules that apply to the host notcovered by the modular transmitter grant of certification .If the grantee markets their product asbeing Part 15SubpartBcomp…
