ARTS
This system is designed to inform you when you and
another ARTS-equipped station are within communi-
cation range.
During ARTS operation, when the radio receives the
correct ARTS signal, a short beep will sound and the
"In" (meaning "In Service") notation will be displayed
on the sub-LCD . 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" ("Out of Service") will be displayed on the
sub-LCD . If you subsequently move back into range,
as soon as the other station transmits, a short beep
will sound and "In" will be displayed again on the
sub-LCD .
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.
In the 16-key and 4-key versions, the three-digit code
of the station which paged you will appear on your
radio's LCD.
