Repeater or Direct Operation
The REPEATER operation increases the radio’s range by

repeater and connect directly to another radio. The transmit and
receive frequencies are the same.

Monitoring Features
Radio users who switch from analog to digital radios often
assume that the lack of static on a digital channel is an
indication that the radio is not working properly. This is not the
case.
Digital technology quiets the transmission by removing the
“noise” from the signal and allowing only the clear voice or data
information to be heard.
Monitor a channel to ensure the channel is clear before
transmitting.
