If the current group channel has RF interference, you can coordinate a group channel change.

• Press TONE/SCN, the current channel and CHCX appears. Use U or V to select your target channel. Check whether the selected channel is vacant, then press D-CALL. Your radio chirps for about 10 seconds while it sends out the channel change signal. As each radio receives the channel change signal, it chirps once; then it changes to the new channel.

To ensure all radios make it to the new channel, we recommend you:

• Operate the radio in an open environment to allow the radio the best range.

• Optimize range during the channel change signal by raising the radio over your head for extra height.

• Do a “roll call” on the new channel to make sure no radio was left behind. If you missed someone, return to the previous channel and issue the signal again.

Your radio has 22 channels and 142 quiet codes. To talk to others, you must be on the same channel and quiet code if it is activated.

To select a channel and quiet code:

1. Repeatedly press U or V to select a channel (1-

22).

2. Press TONE/SCN. The quiet code number ﬂ ashes.

3. Repeatedly press U or V to select a quiet code (oFF or 1 - 142).

4. Press TONE/SCN again.

• Quiet codes limit authorized users and reduce interference.

NOTES

• Code oFF indicates that you have no quiet code selected. Your radio can receive a signal regardless of other radio settings.
