Group Calling - GME GA9800 Instruction Manual

Receiving Signals while Scanning in the QUIET Mode
• If a normal signal is received on an open channel, scanning will pause while the channel
is busy and will resume scanning 5 seconds after the channel becomes clear. (If you were
scanning in Group Scan mode, the radio may switch between the open channel and the
Priority channel - this is normal).
• If a normal signal is received on a Quiet channel but your Selcall Ident is not detected, the
signal will be ignored and scanning will continue.
• 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, 12032, 10233 . . --> , 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.
