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
“
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.

on your radio’s LCD.
