N OTES :
 The Carrier Detect Signal (COR) must be programmed to an auxiliary output pin. The Radio
Connection Chart shows COR programmed to auxiliary output 2, which is pin 8 of the radio
connector. Carrier Detect is Active High (SW1-2 = DN).
 The PTT signal must be programmed to an auxiliary input 5, as per the Radio Connection Chart.
 If the monitor function is required, the MON signal must be programmed to auxiliary input 4, as per
the Radio Connection Chart. Programming the MON signal alters the maximum number of channels
that can be scanned. Normally, a maximum of 15 channels can be scanned, however, use of the
MON function limits the maximum to 8 channels. Pin 7 of the adapter must be connected to the RX
CTCSS Disable Input (MON) pin of the radio. Pin 14 of the adapter must be connected to GRND.
