General Radio Operation
English

Repeater or Direct Operation
The REPEATER operation increases the radio’s range by
connecting with other radios through a repeater. The transmit
and receive frequencies are different.
The DIRECT or “talkaround operation” allows you to bypass the
repeater and connect directly to another radio. The transmit and
receive frequencies are the same.
Procedure:
Press the preprogrammed Repeater/Direct button to toggle
between talkaround and repeater modes.
OR
Follow the procedure below.
1 < or > to Dir.
2 Press the Menu Select button directly below Dir.
3 The display shows Repeater mode if the radio is currently
in Repeater mode.
OR
The display shows Direct mode and the Talkaround icon if
the radio is currently in Direct mode (during conventional
operation only).
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.
This digital technology quiets the transmission by removing the
“noise” from the signal and allows only the clear voice or data
information to be heard.
Use the Monitor feature to make sure a channel is clear before
transmitting.
