"CTCSS Bell"
CTCSS Bell operation is an extension of the
CTCSS encode/decode function described
above: incoming subaudible tones open the
squelch. However, it adds two features to make
this semi-private operation more convenient:
(1) The CTCSS Bell mode displays
the respective band's frequency display.
When you receive a matching CTCSS tone,
the LCD and keypad illuminate and this bell
blinks for a few moments to indicate you re-
ceived a call. So, by looking at the display you
can tell if a call came. You cannot tell, how-
ever, who called. That requires DTMF Paging,
described later.
If you are waiting for a call, it is sometimes
convenient to have the transceiver "ring" to
get your attention. The alert ringer can be set
to ring once, several times or can be disabled
completely (see page 56).
To activate the CTCSS Bell:

Now all incoming calls without a matching
CTCSS tone will be ignored by your receiver.
Any call received with the matching CTCSS tone
will cause the LCD and keypad to illuminate
(unless disabled),
to ring (if the ringer is enabled) as the squelch
opens while the caller transmits. Note that other
stations do not need to be using the CTCSS Bell
function to call you: they can use normal CTCSS
functions of their transceiver.
