Auto-Range Transponder System (ARTS)

ARTS is an analog-only feature designed to inform

you when your radio is out-of-range of other ARTS-

equipped radios.

ARTS-equipped radios transmit or receive signals

periodically to confirm that they are within range of

each other. Your dealer can program your radio to

transmit or receive the ARTS signal.

Your radio provides indications of states as follows:

• First-Time Alert – A tone sounds.

• ARTS-in-Range Alert – A tone sounds, if

programmed.

• ARTS-Out-of-Range Alert – A tone sounds, the

LED rapidly blinks red.

Over-the-Air-Programming (OTAP)

Your radio can be updated by your dealer remotely,

via OTAP, without needing to be physically

connected. Additionally, some settings can also be

configured via OTAP.

While undergoing OTAP, the LED blinks green.

Note: When the radio is receiving high volume data,

the High Volume Data icon appears and channel is

busy. A PTT button press at this time may cause a

negative tone to sound.

Once the programming is complete, a tone sounds,

and your radio restarts (powers off and on again).

Utilities

Setting the Squelch Level

You can adjust your radio's squelch level to filter out

unwanted calls with low signal strength or channels

that have a higher than normal background noise.

Normal Squelch is the default. Tight Squelch filters

out (unwanted) calls and/or background noise;

however, calls from remote locations may also be

filtered out.

Press the programmed Squelch button.
