Multi-Pin Connector 5, Antenna Connector





2 Antenna output signal brown connection to antenna selection control module

Antenna signal input via connection 1 is tested in radio and result is output via connection 2 to antenna selection control module. Function is switched to another antenna when antenna signal is determined to be weak (diversity). This procedure is not audible to the customer.

Multi-Pin Connector 6, Antenna Connector





1 Transparent color connection for antenna output signal from antenna selection control module

Antenna signal input via connection 1 is tested in radio and result is output via connection 2 to antenna selection control module. Function is switched to another antenna when antenna signal is determined to be weak (diversity). This procedure is not audible to the customer.
