Receiving Selcalls
When your radio receives it’s Selcall Ident, an alarm will
sound to alert you to the call. Initially the alarm will
beep urgently at 2 beeps per second, then, if the call
is not answered, it will slow to around 1 beep every 3
seconds. It will then continue to beep indefinitely until
you cancel it.
In addition to the alarm, the
symbol will appear on
the display along with the callers Selcall Ident or ALPHA
label to inform you of the caller’s identity.

To return the call:

the caller.
To cancel the alarm:
Briefly press the PTT switch. The alarm will be
cancelled and the channel will be open for normal
communication. You can now talk on the channel in the
usual way.
QUIET MODE
The Quiet Mode mutes the receiver to prevent incoming
signals from being heard in the speaker until your
Selcall Ident is received. In this way you can monitor a
busy channel for personal calls without being disturbed
by unwanted signals. If your Selcall Ident is received,
the Quiet Mode is cancelled and all incoming signals
are heard in the speaker.
Setting up the Quiet Mode
To setup the Quiet Mode you must first ‘tag’ the
channels that you want to stay Quiet, then activate the
Quiet Mode. Once the Quiet Mode is activated, tagged
channels will remain Quiet to all incoming signals
unless your Selcall Ident is received. Channels not
tagged will remain open to all signals and will operate
normally.
To tag individual channels for QUIET operation:
1. Select the required channel.
2. Briefly press F then press and hold QUIET until the
radio beeps. ‘Q’ will appear on the lower right of
the display channel number indicating the selected
channel is now tagged for Quiet operation.
To remove the QUIET tag from individual
channels:
1. Select a channel that has been tagged for Quiet
operation. ‘Q’ will be displayed.
2. Briefly press F then hold QUIET until the radio
beeps. ‘Q’ will disappear indicating this channel is no
longer tagged for Quiet operation.

operation (you cannot activate the Quiet Mode
unless you have selected a ‘tagged’ channel). ‘Q’ will
be displayed.
