Arts (Automatic Range Transponder System) - Yaesu VX-3R Operating Manual

ARTS™
( A
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 use-
ful 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 acti-
vated, 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 IN RNG" as opposed to the out of range display "OUT
IN RNG IN RNG
IN RNG
RNG" in which ARTS™ operation begins.

Whether you talk or not, the polling every 15 or 25 seconds will
continue until you de-activate ARTS™. You can program your radio to transmit your callsign
every 10 minutes, via CW, 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
"OUT RNG OUT RNG." If you move back into range, your radio will again beep, and the display will
OUT RNG OUT RNG OUT RNG
change back to the "IN RNG
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 re-
sume normal operation. This is a safety feature designed to prevent accidental loss of
contact due to channel change, etc.
