ANUAL
ARTS™
(
Auto Range Transpond System
)
This system is designed to inform the operator when you
and another ARTS™-equipped transceivers and stations
are within communication range using the DCS Encoder/
Decoder.
During ARTS™ operation, when the radio receives an
incoming ARTS™ signal, a short beep will sound twice
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, causing a short triple beep to sound and
“
OUT SERV
” (“Out of Service”) will be indicated on the
display for 2 seconds. Moving back into communications
range as the ARTS™ signal transmission from another
transceiver or station is back in range, a short beep will
sound twice again and “
IN SERV
” (“In Service”) will be
indicated on the display for 2 seconds.
