55FT-2900E O PERATING M ANUALThe ARTS™ feature uses DCS signaling to inform both parties when you and anotherARTS™-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 othermembers of your group.Both stations must set up their DCS codes to the same code number, then activate theirARTS™ 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 RNGIN RNGIN RNGIN RNGIN RNG” as opposed to the out of range display “OUTRNGOUTRNGOUTRNGOUTRNGOUTRNG”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 callsignvia 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 sensethat no signal has been received, three beeps will sound, and the display will revert to“OUTRNGOUTRNGOUTRNGOUTRNGOUTRNG.” If you move back into range, your radio will again beep, and the display willchange back to the “IN RNGIN RNGIN RNGIN RNGIN RNG” indication.During ARTS™ operation, your operating frequency will continue to be displayed, but nochanges may be made to it or other settings; you must terminate ARTS ™ in order to resumenormal operation. This is a safety feature designed to prevent accidental loss of contact dueto channel change, etc.Basic ARTS™ Setup and Operation1. Assign the ARTS™ feature to the microphone’s programmable button ([P1], [P2], [P3],or [P4]), per the discussion on page 65.2. Set your radio and the other radio(s) to the same DCS code number, per the discussionon page 25.3. Press the assigned microphone’s programmable button momentarily. You will observethe “OUTRNGOUTRNGOUTRNGOUTRNGOUTRNG” display on the LCD. ARTS™ operationhas now commenced.4. Every 25 seconds, your radio will transmit a “polling” callto the other station. When that station responds with its ownARTS™ polling signal, the display will change to“IN RNGIN RNGIN RNGIN RNGIN RNG” to confirm that the other station’s polling codewas received in response to yours.ARTS™ (AUTOMATIC R ANGE TRANSPONDER SYSTEM)
