- FCC Rule parts 15C(15.247) This module has been granted modular approval as below listed FCC rule parts. Summarize the specific operational use conditions The OEM integrator should use equivalent antennas which is the same type and equal or less gain then an antenna listed in this instruction manual. RF exposure considerations under the following condition:
The module has been certified for integration into products only by OEM integrators
-The antenna(s) must be installed such that a minimum separation distance of at least 20 cm is maintained between the radiator (antenna) and all persons at all times.
-The transmitter module must not be co-located or operating in conjunction with any other antenna or transmitter except in accordance with FCC multi-transmitter product procedures.
-Mobile use required. As long as the three conditions above are met, further transmitter testing will not be OEM integrators should provide the minimum separation distance to end users in their end-product manuals. 2020 LG.
