ANUAL

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 it 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, 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 RANGE

IN RANGE

” as opposed to the out of

range display “OUT RANGE

OUT RANGE

” in which ARTS

operation be-

gins.

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, 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 RANGE

OUT RANGE

.” If you move back into range, your radio will again beep, and the display

will change back to the “IN RANGE

IN RANGE

” 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.
