Deleting a Nuisance Channel

If a channel continually generates unwanted calls or noise (termed a “nuisance” channel), you can temporarily remove the unwanted channel from the scan list.

This capability does not apply to the channel designated as the Selected Channel.

Procedure:

1When your radio “locks on to” an unwanted or nuisance channel, press the programmed Nuisance Channel Delete button until you hear a tone.

2Release the Nuisance Channel Delete button. The nuisance channel is deleted.

Deleting a “nuisance” channel is only possible through the programmed Nuisance Channel Delete button. This feature is not accessible through the menu.

Restoring a Nuisance Channel

Procedure:

To restore the deleted nuisance channel, do one of the following:

Turn the radio off and then power it on again, OR

Stop and restart a scan via the programmed Scan button or menu, OR

Change the channel via the Channel Selector Knob.

Vote Scan

Vote Scan provides you with wide area coverage in areas where there are multiple base stations transmitting identical information on different analog channels.

Your radio scans analog channels of multiple base stations and performs a voting process to select the strongest received signal. Once that is established, your radio unmutes to transmissions from that base station.

The LED blinks yellow and the vote scan icon appears on the status bar.

To respond to a transmission during a Vote Scan, follow the same procedures as Responding to a Transmission During a Scan on page 42.
