To achieve this, the 10 radios you are calling must be
programmed with sequentially numbered SelCall Idents.
e.g. 14530, 14531, 14532, 14533.. -->, 14539
Transmitting the SelCall Ident 14531 will only activate the
alarm in the radio with the SelCall Ident of 14531. However
transmitting 1453A will activate the alarms in all radios with
Idents 14530 through 14539 (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 will
need to re-program the SelCall Idents in your radios.
Sending a Group Call Ident
1. Press the
CALL
button.
is displayed along with the
last sent or received SelCall Ident. If an ALPHA label is
displayed you will need to press
then
to
switch to Numeric Mode.
2. Press and hold the
LEVEL
key until the radio beeps. The
right-hand digit of the SelCall Ident will flash.
3. Press the
or
keys to select ‘A’ in the flashing digit
position. This is the special code that will create the Group Call.
4. Briefly press the
LEVEL
key again to select the next digit position.
5. Continue entering the other 4 digits as required. The
SelCall number is now ready to send.
6. Press and hold the
CALL
button. A long beep will be heard
and the radio will transmit the SelCall Ident.
Programming group calls for 100 radios (when this is enabled
in your radio) is identical except that you will need to select ‘A’
for the last 2 digits (eg. 123AA). For 1000 radios you will need
to select ‘A’ for last 3 digits (eg. 12AAA).
e.g.:
Sending Ident 145AA will call 100 radios with Idents
14500 -> 14599
Sending Ident 14AAA will call 1000 radios with Idents
14000 -> 14999
You can also arrange to send SelCalls to every tenth radio by
setting the second digit to A.
e.g.
Sending Ident 145A5 will call radios 14505, 14515, 14525,
14535.. --> 14595
Call acknowledge in Group mode
There is no call acknowledge when sending group calls. This is
to prevent all the radios in your group from trying to respond
to your SelCall transmission at the same time.
Storing Group Call Idents
Group Call Idents can be stored in memory in the same way
as a standard SelCall Ident.
Receiving Group Calls
Receiving a Group Call is identical to receiving a normal
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.
