will appear and the

with your working channel number.
Operating in the Dual Watch Mode:
Operation in the Dual Watch mode is identical
to the Group Scan mode, with the selected
channel acting as a single group channel. As
with Group Scan, signals on your working
channel will have priority over those on the
selected channel.
Talking on the Working Channel:
To talk on the working channel while Dual
Watching, simply press the PTT switch. The
TX7000 will go straight to the working channel
and will remain there for as long as the channel
remains active. During this time you can
converse normally on the channel even though
Dual Watch is still selected. When your
conversation has finished and the channel has
been inactive for 5 seconds, the radio will
resume Dual Watching .
SELCALL (SELECTIVE CALLING)
Overview
If Selcall has been enabled on your radio, it will
have been pre-programmed with its own unique
identifying code. You radio may also allow you
to transmit these 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 radio's 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.
Receiver Quiet Mode
The Selcall "Quiet" function overrides the
normal squelch operation, forcing the radio to
remain quiet even if signals are being received -
until someone transmits your Selcall code
. The
"Quiet" mode will then be disabled, an alarm
will sound, and you will be able to converse
normally on that channel.
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
radios quiet muting system will have been
preset for you by your dealer.
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.
• When Quiet is disabled, you will be able to
hear all transmissions on the channel.
When quiet is enabled, you will see the
QUIET
icon on the display.
Your radio may be programmed to allow you to
decide which channels you wish to use as quiet
channels. This allows you to tag selected
channels to remain quiet until you receive a
Selcall, while others will remain open to all
signals. The
Quiet
key is also used to tag these
channels.
