Squelch Off
Squelch Off is an analog channel function that, when enabled, keeps the receiver unsquelched
(i.e., not
muted) even when there is no signal on the selected channel. When enabled, the
icon appears in
the top of the display and call audio on the channel (or receiver noise) is routed to the radio’s speaker.
To toggle squelch between enabled and disabled, press the pre-configured Squelch Off shortcut key.
To momentarily turn squelch off, depress the pre-configured Squelch Off Momentary key. When this key is
released, squelch turns back on.
Telephone Interconnect Calls
If an analog channel’s repeater site equipment is connected to a Public Switched Telephone Network (PSTN)
gateway system, the radio can make a phone call through this channel and phone system.
