Radio Transceiver Module
The Radio Transceiver Module’s range is 450–470 MHz, and the six channel frequencies can be
programmed in steps of 12.5 kHz at the factory to the customer’s specifications. The Radio Transceiver
can also be programmed for CTCSS or DPL.
N OTES :
1. When the Radio Transceiver Module is programmed for CTCSS or DPL it can only communicate with
other radios that have the same CTCSS or DPL programming.
2. Certain transmit and receive frequencies within the radio’s range are unavailable. Refer to Table 5
below for these frequencies. Do not attempt to program the radio for these frequencies.
