Talk Back
You can respond to any calls received during the scan process by pressing the PTT.
Priority Channel Scan
Enable you to constantly monitor & keep an update on the activities on the most commonly used
channel so that messages will not be missed. Check with your dealer for details.
When scanning remains on a non-priority channel, the radio continues to monitor activities on
the priority channel, and jumps to the priority channel if activity is detected.

Busy Channel Lockout (BCL)

Avoid interference with the users using the same channel by preventing transmission if another
talk group is already on the air. The radio will generate a continuous tone upon PTT press if a
transmission is not allowed. Release the PTT to cancel the tone.
See Glossary for definition of BCL.

Low Battery Alert

For extra convenience, LED flashes red and a low-pitched tone sounds at every ten seconds to
alert users to recharge the battery should the battery level run low.

Voice Operated Transmit (VOX)

You can transmit hands free with the use of optional accessories. The radio will automatically
begin transmitting when you speak, and terminate transmitting when you stop talking. See
