This system is designed to inform you when you and
another ARTS
TM
-equipped station are within com-
munication range.
During ARTS
TM
operation, when the radio receives
an incoming ARTS
TM
signal, a short beep will sound,
and “
IN SERV
” (“In Service”) will be indicated on
the display for 2 seconds
. If you move out of range
for more than two minutes, your radio senses that no
signal has been received; a short triple-beep will
sound, and “
OUT SERV
” (“Out of Service”) will be
displayed on the display for 2 seconds
. If you sub-
sequently move back into communication range, as
soon as the other station transmits, a short beep will
sound and “
IN SERV
” will be indicated again on the
display for 2 seconds
: Except on Non-LCD version.
