Briefly press the
key to monitor signals on the channel.
When you release the
key, Silent mode is restored and
the radio will become quiet again.
NOTE:
You will only have a brief moment to monitor the
channel for signals as holding the
key for more than a
few seconds will switch the radio off.
SELECTIVE CALLING
Your radio has a Selective Calling system known as SelCall
that operates like a telephone. Your radio is pre-programmed
with its own unique SelCall Identification number. If this
number is called by another radio, your radio will beep to
alert you. If you do not want to hear any other activity while
waiting on a channel, you can select the QUIET mode. Your
radio will then remain quiet to all incoming signals until your
SelCall number is called.
Your radio will allow you to store up to 10 of your most
frequently called SelCall numbers in memory and each
number can be labelled for easy identification.
SelCall Identification Number
Your radio is factory programmed with its own unique SelCall
Identification Number (Ident). This number identifies your
radio from others in your area. Your radio’s own SelCall Ident
will be displayed for a few seconds to the left of the channel
display when you first turn the radio on. You will need to
make your Ident known to anyone who may need to call you
using SelCall.
NOTE:
Although your radio is factory-programmed with a
unique SelCall Ident, you can change your Ident to another
number if required (see
SelCall Memories
on next page).
SelCall Ident Labels
When storing SelCall Idents, you can add labels to each one
to make it easier to identify whose Ident you are recalling. In
addition, if an incoming SelCall matches one of your stored
Idents, the label can be displayed instead of the Ident.
To add or display labels, your radio must be in the ALPHA
mode. To switch between ALPHA mode and NUMERIC mode,
briefly press the
F
key followed by the
ALPHA
key. ‘ALPHA’
or ‘NUMER’ will be displayed briefly to the left of the channel
display to indicate the selected mode.
The QUIET Mode
Your radio can be set to monitor signals on a busy channel
but remain QUIET unless it receives its own SelCall Ident.
In this way, you won’t be disturbed unless someone calls
you. When your SelCall Ident is received, the QUIET mode is
deactivated and an alarm sounds to alert you to the call. You
can then converse normally on the channel. To use the QUIET
mode, refer to the QUIET mode section further below.
NOTE:
The QUIET mode overrides the normal Squelch system
to ensure that the radio remains quiet even when the channel
is busy. When QUIET is set, you may see the icon appear
on the display indicating the channel is being used. However,
unless someone transmits your SelCall Ident, nothing will be
heard in the speaker.
You can activate the QUIET mode on individual channels i.e.
some channels can be set to remain Quiet while others can
remain open to all incoming signals.
