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 your 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.
Use the Monitor feature to make sure a channel is clear before
transmitting.
Monitoring a Channel
Procedure:
1 Press the preprogrammed Monitor button to toggle
Monitoring on.
2 Press and hold the PTT button to transmit. The LED lights
up solid red.
3 Release the PTT button to receive (listen).
The Carrier Squelch indicator appears on the display when you
monitor a channel via the preprogrammed Monitor button.
Conventional Mode Operation
Your radio may be preprogrammed to receive Private-Line
®
(PL) calls.
Procedure:
1 Momentarily press the Monitor button to listen for activity.
The Carrier Squelch indicator appears on the display.
2 Press and hold the Monitor button to set continuous
monitor operation. The duration of the button press is
programmable.
3 Press the Monitor button again, or the PTT button, to return
to the original squelch setting.
If you try to transmit on a receive-only channel, you hear an
invalid tone until you release the PTT button.
