Switching Between Repeater or Direct
Operation Button
The Repeater Operation increases the radio
coverage area 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.
Perform one of the following actions:
• Press the preprogrammed Repeater/Direct
switch to toggle between talkaround and
repeater modes.
•
or to
Dir
and press the Menu Select
button directly below
Dir
.
The display shows
Repeater mode
if the radio is
currently in Repeater mode.
The display shows
Direct mode
and the Talkaround
icon if the radio is currently in Direct mode (during
conventional operation only).
Monitor Feature
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 allows only
the clear voice or data information to be heard.
Use the Monitor feature to make sure a channel is
clear before transmitting.
Monitoring a Channel
• Monitoring a Channel in Conventional Modes:
a) Lift the microphone off hook.
b) Listen for activity on that channel.
c) Adjust the
Volume Rocker if necessary.
