3. Press and hold in the PTT switch for five seconds to find out the persons who are activating the EAI
feature. The lost operator’s radio will beep loudly, and its transmitter will respond repetitively. You may
now begin direction-finding efforts.
4. You may select the ATT (Front End Attenuator) level among “ATT 1 (10 dB),” “ATT 2 (50 dB),” and “ATT
OFF” by pressing the [BAND] key to reduce the signal. The ATT is often useful in helping you locate the
missing person’s radio, as peaks in weaker signals are more easily observed.

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, 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
“OUT 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
™
.
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 “OUT RNG.” 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. Set your radio and the other radio(s) to the same DCS code number, per the discussion on page ??.
