Selective Calling - GME TX3600 Series Instruction Manual

• If the radio was scanning when scan was cancelled, it
will return to the last selected channel (as displayed in
the bottom right of the display).
Scanning in Group Scan Mode
Scanning in Group Scan mode will allow you to transmit
and receive normally on your working (priority) channel but
will also let you scan and listen to several other channels
when the working channel is free. The receiver will continue
to scan the other group Scan channels oNLy WhILE ThErE
ArE No SIgNALS oN ThE WorKINg ChANNEL. Pressing
the PTT switch at any time will take you straight to your
working channel.
The working channel is normally scanned after every
second Group Scan channel (although this can be altered
by your retailer).
e.g. Using working channel 10 with group Scan channels
1, 3, 6, 8, 15 and 26.
As with the Open Scan mode, your radio will display rapidly
changing numbers to indicate the channels being scanned.
In addition the lower section of the LCD will display 'gS'
to indicate that it is the Group Scan mode, along with the
working channel number. If any channels have alphanumeric
labels, the labels will not be displayed while scanning.
Receiving Signals on the Working Channel
If a signal appears on the working channel while scanning,
the receiver will lock onto the channel and will remain there
for as long as the channel is busy – and for 5 seconds after
the transmission ceases. This allows the TX3600 Series to
hold the channel between short breaks in the conversation.
once the channel has remained clear for 5 seconds, the
radio will resume scanning.
If a signal appears on the working channel while your
radio is locked onto a group Scan channel, the receiver
will switch straight to the working channel. The receiver
will now continue to monitor the working channel for as
long as it remains busy. During this time you can transmit
on the working channel in the usual way.
Receiving Signals on a Group Scan Channel
If a signal is received on a Group Scan channel, the
receiver will lock onto it and will remain there for as long
as the channel remains busy, and for 5 seconds after the
transmission ceases – AS LoNg AS ThErE ArE No SIgNALS
oN ThE WorKINg ChANNEL. During this time, the receiver
will continue to check for signals on the working channel
every couple of seconds resulting in a series of small breaks
in the reception of the 'locked' channel. If no signals are
heard on the 'locked' channel after 5 seconds, the radio
will resume normal scanning.

To stay on a busy Group Scan channel, briefly press the
SCAN key. The radio will exit the SCAN mode and stay on
the busy channel. you can now transmit normally on
that channel.
Note: At this point the radio will no longer be monitoring
your working channel.
To resume Group Scan briefly press the SCAN key again.
If Selcall has been enabled on your radio, it will have been
pre-programmed with its own unique Identifying code. your
radio may also allow you to transmit Selcall codes, allowing
you to call others who are also using the Selcall system.
Selective Calling is a secure signalling system that allows
individual radios to be selectively called without disturbing
other radios sharing the same channel. Each radio can be
pre-programmed with a unique code (called a Selcall Ident).
The radio can then be set to remain totally quiet while it
monitors the channel for Selcall signals. Any incoming Selcall
code is compared with its own code. If the two codes match,
it knows it is being called and sounds an alarm to alert you.
It also displays the caller's unique code or an alphanumeric
label Identifying the caller to you. In this way, even if you
are away from your radio when the call is received, you will
still know that you were called. you can then return the call
at your convenience. If further calls are received, the most
recent caller is displayed.
A special group code may also be available to you which
will allow specific groups of radios to be selectively called
without disturbing other individuals or groups.
OPERATING IN THE qUIET MODE
The QUIET mode prevents any incoming transmissions from
being heard in your TX3600 Series speaker until your Selcall
Ident is received. This allows you to monitor a busy channel
for calls without being disturbed by unwanted signals.
When your Selcall Ident is received, the QUIET mode
is cancelled and all incoming signals will be heard in
the speaker.
If your radio is programmed with a QUIET key, you will be
able to manually set your receiver's Selcall Quiet muting
system. If not, your radio's quiet muting system will have
been preset for you by your retailer.
The QUIET key
If fitted, the QUIET key can be used with Selcall to enable or
disable quiet operation.
• When Quiet is enabled, you will not hear any signals
on the channel until someone specifically calls you
using Selcall.
