'M’ will be displayed on that Channel to indicate that it is
in the scan memory . For more details, see the section on
'Scanning' in this manual .
RECEIVING SELCALLS ON YOUR
RECEIVE-ONLY CHANNELS
If your TX4400 receives its Selcall code on a Receive-Only
Channel, it will respond in the usual way, except that it
cannot automatically transmit two quick beeps back to the
caller since there is no transmit frequency . For more details,
see the section on 'Selcall' in this manual .
Using the PAGE function with your Receive-Only Channels .
You can monitor Receive-Only Channels with the Page
function in the same way as you can with CB Channels . If
your Selcall is received on the Receive-Only Channel your
radio will page you the same as it would if the call was
received on a normal CB Channel, except that it cannot
respond to the caller with two quick beeps since there is no
transmit frequency . For more details, see the 'Page Mode'
section on in this manual .
CTCSS
There is no provision for CTCSS operation on the Receive-
Only Channels .
SELECTIVE CALLING
WHAT IS SELCALL
Your TX4400 has a Selective Calling (Selcall) system that
operates like a telephone . Your radio has been programmed
with its own unique Selcall Identification number . When
this number is called by another radio, your TX4400 will
beep to alert you .
If you do not want to hear any other activity while waiting
on a Channel, you can push the
QUIET
key . The radio will
then remain quiet to all incoming signals until your number
is called . Your radio allows you to store up to ten of your
most frequently called numbers in memory . Each number
can be labelled with a 5-letter name for easy identification .
SELCALL IDENTIFICATION NUMBER
(IDENT)
Your TX4400 is factory programmed with its own unique
Ident . This number identifies your radio from others in your
area . You will need to make your Ident known to anyone
who may need to call you with Selcall . Whenever your
TX4400 hears a Selcall signal, it compares the incoming
Ident with it’s own . If the two Idents match, the radio
knows it is being called and sounds an alarm to alert you
to the call .
The Selcall Ident for your radio is printed on the label on
the rear panel and is also stored in Selcall memory 12
(see section below on programming the Selcall memories) .
The Ident is the last 5 digits of the radio's serial number .
Note:
The Selcall Ident is also displayed to the right of
the Channel number for one second each time the radio
is turned on . Although your radio's Selcall Ident is pre-
programmed at the factory, you can arrange to have your
Dealer change it if required .
SELCALL IDENT NAMES
The TX4400 allows you to name all 10 of the Selcall Idents
stored in memory using a 5 character word . The name can
then be stored in memory with the Ident making it easier to
identify whose Ident you are recalling from the memory . In
addition, if an incoming Selcall matches one of the Idents
stored in the memory, its name can be displayed to make it
easier for you to identify the caller .
THE QUIET MODE (Q)
Your TX4400 can be set to listen on a busy Channel but not
allow any sound to reach the speaker UNLESS it receives its
own Selcall Ident . In this way, your radio can monitor a busy
Channel without disturbing you, but still let you know when
you are being called .
• The QUIET mode overrides the normal Squelch system
to ensure that the radio remains quiet even when the
Channel is busy or the Squelch is ‘opened’ with the
Squelch control . When QUIET is set, you may see 'BUSY'
appear on the display and signal strengths appear on the
display indicating the Channel is being used . However,
unless someone transmits your Selcall Ident, nothing will
be heard in the speaker .
• The QUIET mode can be set to work on specific Channels
i .e . some Channels can be set to remain Quiet while
others can remain Open to all incoming signals .
When a signal containing 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 .
Note:
Setting the QUIET mode is not mandatory . You can
still use Selcall on any Channel whether the QUIET mode is
set or not .
SELCALL MEMORIES
Your TX4400 is fitted with 13 Selcall Ident memories .
• Memory locations 1 - 10 are available for normal use
and can be programmed with your favourite Selcall
Idents and Alpha Names .
• Memory locations 11 - 13 are reserved for use by the
radio as follows:
