ARTS™ (Automatic Range Transponder System)
The ARTS™ feature uses DCS signaling to inform both parties when you and another
ARTS™-equipped station are within communications range. This may be particularly
useful during Search-and Rescue situations, where is important to stay in contact with
other members of your group.
Both stations must set up their DCS codes to the same code number, then activate their
ARTS™ feature using the command appropriate for their radio. Alert ringers may be
activated, if desired.
Whenever you push the
PTT switch, or every 25 (or
15) seconds after ARTS™ is activated, your radio will
transmit a signal which includes a (subaudible) DCS
signal for about 1 second. If the other radio is in range,
the beeper will sound (if enabled) and the display will
show “
IN RNG
” as opposed to the out of range display
“
OUTRNG
” in which ARTS™ operation begins.
Whether you talk or not, the polling every 15 or 25 seconds will continue until you de-
activate ARTS™. Every 10 minutes, moreover, you can have your radio transmit your
callsign via CW, so as to comply with identification requirements. When ARTS™ is
de-activated, DCS will also be deactivated (if you were not using it previously in non-
ARTS™ operation).
If you move out of range for more than one minute (four pollings), your radio will sense
that no signal has been received, three beeps will sound, and the display will revert to
“
OUTRNG
”. If you move back into range, your radio will again beep, and the display will
change back to the “
IN RNG
” indication.
During ARTS
™
operation, your operating frequency will continue to be displayed, but
no changes may be made to it or other settings; you must terminate ARTS
™
in order to
resume normal operation. This is a safety feature designed to prevent accidental loss of
contact due to channel change, etc.
Basic ARTS
™
Setup and Operation
1. Assign the ARTS™ feature to the microphone’s programmable button ([ P1
], [
P2
], [
P3
],
or [
P4
]), per the discussion on page 56.
2. Set your radio and the other radio(s) to the same DCS code number, per the discus-
sion on page 23.
3. Press the assigned microphone’s programmable
button momentarily. You will observe the “
OUTRNG
”
display on the LCD. ARTS™ operation has now
commenced.
4. Every 25 seconds, your radio will transmit a “polling”
call to the other station. When that station responds
with its own ARTS™ polling signal, the display will
change to “
IN RNG
” to confirm that the other station’s
polling code was received in response to yours.
5. Press the assigned microphone’s programmable button momentarily to exit ARTS™
operation and resume normal functioning of the transceiver.
