Up to this point, this manual has only described
the operation of the functions and features
programmed into the TX4200 when it leaves the
factory. The alternative ‘Dealer Programmable
Features’ described above were not included in
the main section of the manual to prevent
confusion.
If you decide to have your TX4200
re-programmed to one of the dealer
programmable options, you should refer to this
section for a description on how to use the new
feature.
Group Scan Mode Options
Group Scan Mode
(factory setting).
This is the standard factory setting. A full
description of the factory default Group Scan
mode is described on page 10 of this manual.
Call Waiting Mode
(dealer programmable option)
The ‘Call Waiting’ mode is a variation on the
original Group Scan mode. It allows you to scan
a group of channels and monitor the Priority
channel. As with the standard ‘Group Scan’
mode, the Priority channel is scanned after every
second ‘group’ channel. If a signal appears on a
‘group’ channel, the receiver will ‘lock’ onto it,
and will remain there while the channel is busy,
AS LONG AS THERE ARE NO SIGNALS ON
THE PRIORITY CHANNEL. During this time, the
receiver will continue to check the priority
channel for signals every 2 seconds, resulting in
a series of breaks in the reception of the locked
channel. If no further signals are heard after 5
seconds, the radio will resume scanning.
If a signal appears on the priority channel at
this time, the receiver will switch straight to
the priority channel and will give 3 short
beeps to warn you that the channel you are
listening to has changed. It will then stay on
the Priority channel for as long as it remains
busy. However, if no further signals are heard
after 5 seconds, the radio will resume
scanning.
If a signal appears on any channel (group or
Priority), and the receiver ‘locks’ onto it, you
can pick up the microphone and talk on that
channel.
• If the ‘locked’ channel is the Priority
channel, the scan function will pause
indefinitely and the radio will remain on
that channel. When you have finished with
the Priority channel, press the
SkIP
button
on the microphone to resume scanning.
• If the ‘locked’ channel is a ‘group’ channel,
transmitting on that channel enables the
‘Call Waiting’ mode. You can now
communicate on the channel in the usual
way and the receiver will continue to
check the Priority channel for signals
every 2 seconds. If a signal appears on
the Priority channel, the receiver will give
you 3 short beeps to warn you that the
Priority channel is
now busy,
but will not
switch over
. Instead it will remain on the
‘group’ channel, giving you the option of
staying where you are or
manually
switching over to the Priority channel.
During this time, the lower section of the
display will flash as a visual reminder that
the Priority channel is busy. If the Priority
channel remains busy, the radio will repeat
the 3 beeps at 15 second intervals.
Once you have finished your conversation
on the ‘group’ channel, simply wait a few
seconds. Normal scanning will then
resume automatically.
To switch to the Priority channel while in
the ‘Call Waiting’ mode, briefly press the
Channel selector
PRI
knob. Scan will be
cancelled.
NOTE:
If the PTT switch is pressed
while
scanning
, it will be ignored and a low beep will
be heard.
Appending 4 or 5 digit Idents to your
Selcall Signal
When your TX4200 transmits a Selcall to
another TX4200, it attaches it’s own Ident to the
end of the signal. This allows the other radio to
display your Ident so they will know who it was
who called (see “Transmitting a Selcall Ident”
