ARTS

UTOMATIC
Operation
The ARTS feature uses DCS signaling to inform both par-
ties when you and another ARTS-equipped station are
within communications range. This may be particularly
useful during Search-and Rescue situations, where is im-
portant 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 sec-
ond. If the other radio is in range, the beeper will sound (if
enabled) and the display will show "In Service" as op-
posed to the out of range display "Out Service" in which
ARTS operation begins.
Whether you talk or not, the polling every 15 or 25 sec-
onds will continue until you de-activate ARTS. 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 re-
vert to "Out Service." If you move back into range, your
radio will again beep, and the display will change back to
the "In Service" indication.
During ARTS operation, your operating frequency will con-
tinue 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.
