ARTSTM (AUTOMATIC RANGE TRANSPONDER SYSTEM)

BASIC ARTSTM SETUP AND OPERATION

1.Set your radio and the other radio(s) to the same DCS code number, per the discussion on page 36.

2.Press the key, then press the key. You will observe

the “OUT RANGE” display on the LCD below the operating frequency. ARTSTM operation has now commenced.

3. Every 25 seconds, your radio will transmit a “polling” call to the other station. When that station responds with its own ARTSTM polling signal, the display will change to “IN RANGE” to confirm that the other station’s polling code was received in response to yours.

4.Press the key to exit ARTSTM operation and resume normal functioning of the transceiver.

2.Rotate the DIAL knob to select Set Mode Item 6: ARTS

INTERVAL.

3.Press the key briefly to enable adjustment of this Set

Mode Item.

5.Press the PTT switch briefly to save the new setting and

exit to normal operation.
