This system is designed to inform you when you and
another ARTS™-equipped station are within commu-
nication range.
During ARTS™ operation, when the radio receives
the correct ARTS™ signal, a short beep will sound
and the “ ” (meaning “In Service”) notation will
be displayed on the sub-LCD
ø
. If you move out of
range for more than two minutes, your radio senses
that no signal has been received; three short beeps
will sound, and “ ” (“Out of Service”) will be dis-
played on the sub-LCD
ø
. If you subsequently move
back into range, as soon as the other station transmits,
a short beep will sound and “ ” will be displayed
again on the sub-LCD
ø
.

This system allows paging and selective calling, using
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 will sound. The three-digit
code of the station which paged you will be displayed
on your radio’s LCD.
