Connections 7 and 8, Antenna Connections





1 Transparent connection for antenna input signal, FM from antenna
2 Beige connection for antenna output signal FM to antenna (diversity, antenna selection)

• The antenna signal input from connection 1 is checked in the radio and the result sent via connection 2 to the antenna. If the antenna signal is too weak, the radio then switches to another antenna (diversity). This process is not audible to the customer.
