• If a signal containing your Selcall Ident
is received on any channel – Open
or Quiet – both scanning and QUIET
modes will be cancelled and the
receiver will stay on that channel.
In addition, the alarm will beep to
alert you to the call and the callers
Ident or ALPHA Name will be
displayed. The channel will now be
open for normal transmission
and reception.
TIP: To ensure reliable Selcall detection
when scanning in the Open Scan mode, it is
recommended that you restrict the number of
channels in the Scan group to 10 or less.
GROUP CALLING
The TX6200’s Selcall system includes a
Group Call function which allows you to
call up to 10 radios simultaneously. This
can be useful in an emergency situation
where you may need to transmit a
message to a number of radios in
your group.
The Group Call function works by
allowing you to enter a special ‘group
code’ into the last digit position of the
Selcall Ident you are sending. The ‘group
code’ appears as an ‘A’ when displayed
in the radio. When this ‘group code’ is
received, it substitutes for any other
number in the last digit position. As long
as the first 4 digits of the Selcall you
are sending match those of the radios
you are calling, their Selcall alarm will
be activated as if their full 5 digit Selcall
Idents had been received.
To achieve this, the 10 radios you are
calling must be programmed with
sequentially numbered Selcall Idents.
e.g. 12030, 12031--> 12039
• Transmitting the Selcall Ident 12031
will only activate the alarm in the radio
with the Selcall Ident of 12031.
• Transmitting 1203A will activate the
alarms in all radios with Idents 12030
through 12039 (a total of 10 radios).
If the radios in your fleet do not have
sequentially numbered Selcall Idents and
you want to make use of this function,
you can arrange for your dealer to
re-program the Selcall Idents in your radios.
Programming and sending group
calls
The process for entering a Group call
Ident is the same as entering a normal
Selcall Ident.
1. Press the CALL key to select the
‘CALL TO’ mode. ‘CALL TO’ is
displayed along with the last sent or
received Selcall Ident. If the radio is
in the ALPHA mode, briefly press the
Monitor key to return to the
Ident display.
2. Enter the required Selcall Ident
as follows:
a. Briefly press the F key. The right-hand
digit of the Selcall Ident will flash.
b. Press the or channel keys to
select ‘A’ in the flashing digit position.
This is the special code that will create
the Group Call.
c. Briefly press the F key again to select
the next digit position.
d. Press the or channel keys to
select the required number in the next
flashing digit position.
e. Repeat steps (c) and (d) to enter all 5
digits as required. When completed,
the first 4 digits of the Ident you have
entered will match all the radios in the
group. The last digit will be set to ‘A’.
Once the Ident has been entered you
have 20 seconds to send it otherwise the
‘CALL TO’ mode will be cancelled and
the Ident you entered will be lost.
