PERATION
ARTS (Auto Range Transpond System)
This system is designed to inform you when you and
another ARTS-equipped station are within commu-
nication range.
During ARTS operation, your radio automatically
transmits for about 1 second every 25 seconds (the
interval is programmed by the Dealer) in an attempt
to shake hands with the other station.
If you move out of range for more than two min-
utes, your radio senses that no signal has been re-
ceived, a ringing beeper will sound, and "OUT OF
SERVICE" will scroll on the LCD. If you subse-
quently move back into range, as soon as the other
station transmits, your beeper will sound, and "IN
SERVICE" will scroll on the LCD.
DTMF Paging System
This system allows paging and selective calling, us-
ing DTMF tone sequences.
When your radio is paged by a station bearing a tone
sequence which matches yours, your radio's squelch
will open and the alert ringer will sound (unless you
have disabled it, as described previously).
The three-digit code of the station which paged you
will be displayed on your radio's LCD.
