STORING GROUP CALL IDENTS

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 .

Selcalls . If your Selcall Ident is received while your TX4400
is in the PAGE mode it will automatically transfer the

be used either while monitoring a single channel or while
scanning in open scan or group scan mode .
To receive the Paging call, the other UHF radio must be
fitted with a CCIR compatible Selcall .
Note:
To allow your TX4400 to operate in the PAGE mode
when your vehicle is unattended, your radio must be
wired so that it has a continuous 13 .8 Volt power source
even when the vehicle's ignition is switched off (see
