ARTS (Auto Range Transpond System)
This system is designed to inform you when you and another ARTS-
equipped station are within communication 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 minutes, your radio senses
that no signal has been received, a ringing beeper will sound, and “OUT
OF SERVICE” will scroll on the LCD. If you subsequently 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, using DTMF tone se-
quences.
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).
The three-digit code of the station which paged you will be displayed on
your radio’s LCD.
