• Transmitting the Selcall Ident 12031 will only activate the
alarm in the radio with the Selcall Ident of 12331.
• Transmitting 1233A will activate the alarms in all radios
with Idents 12330 through 12339 (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

with the last sent or received Selcall Ident.
2. Enter the required Selcall ident as follows:
(a) Press and hold the F (function) key until the radio

send it otherwise the CALL TO mode will be cancelled and
the Ident you entered will be lost.
Note: Where your TX4600 allows it, programming group

to select 'A' for the last two digits (e.g. 123AA). for 1000
radios you will need to select 'A' for last three digits (e.g.
12AAA).
e.g.
100 Radios Ident Sent: 123AA Idents called: 12300 -> 12399
1000 Radios Ident Sent: 12AAA Idents called: 12000 -> 12999

Selcall except that the alarm sound is a LOW tone beep
instead of the normal high tone beep. The Callers Ident or
ALPhA Name appears on the display in the usual way.
