an 'A' when displayed in the radio. When this group code
is received, it substitutes for any other number in the last
digit positions. As long as the first digits of the Selcall you
are sending match those of the radios you are calling, their
Selcall alarms will be activated as if their full 5 digit Selcall
Idents had been received.
To achieve this, the radios you are calling must be
programmed with sequentially numbered Selcall Idents.
e.g. For groups of 10 radios, the Selcall Idents might be:
12030, 12031, 12032, 12033 . . --> , 12039.
Transmitting the Selcall Ident 12031 will only activate the
alarm in the radio with the Selcall Ident of 12031.
• however, transmitting 1203A will activate the alarms in
all radios with Idents 12030 through 12039 (a total of
10 radios).
Similarly, if there were 1000 radios in the group, simply
insert A into the last THREE digit positions of the Selcall
code you are sending. This will substitute for any numbers in
the last THREE digit positions.
i.e. Transmitting 12AAA would activate all radios with
Selcall Idents of 12000 thru 12999.
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 retailer to re-program your radios.
Programming and Sending Group Calls

calls as follows:
1. Briefly press the CaLL key. 'Call To' will appear on

4. Rotate the Channel Selector knob to alter the
right hand flashing digit. Set this digit to 'A'. Now briefly
press the Channel Selector knob to move to the next
digit. If you are calling groups of up to 1000 radios, set
T X 3 6 0 0 S ERI ES
this third digit to 'A' too, otherwise select the required

Ident is displayed.
MC522BC-
hand flashing digit. Set this digit to 'A'. Now briefly press
the A key to move to the next digit. If you are calling

To Send the Selcall Ident:
With the required Selcall Ident displayed in the 'CALL To'
mode, press and hold the CaLL key to transmit the Selcall
code. The 'TX' indicator will appear on the display as the
Selcall code is sent.
Note: you must send the Selcall code within 20 seconds
of the last key press otherwise the Call To mode will be
cancelled and the code will be lost.
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 was
as a standard Selcall Ident.
Simply follow the instructions for storing Selcall Idents in
memory as described earlier in this manual.
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
Name appears on the display in the usual way.
