than other channels in the scan list. The priority channel will also

be checked for activity while the radio is receiving on a non-

priority channel.

Once the receive signal ends, the radio may be programmed to

wait a period of time before resuming scan. When the scan hang

timer has expired, scanning will resume. This scan hang timer

will also be started whenever the radio has ceased transmitting

on a channel. Your dealer or communications coordinator will

customize the scan options for your particular situation; the

following paragraphs detail the available options.

Busy Channel Scan

If no priority channel has been assigned by your dealer or

communications coordinator, all channels in your scan list will be

checked for activity, with no preference given to any channel. If

activity is detected on a channel the radio will stop on that

channel. While the radio is stopped on a channel it may be

temporarily deleted from the scan list by pressing a programmed

Scan Skip or Monitor function button. This is the nuisance

channel delete function. When the radio is turned off, all

channels removed from the scan list using nuisance channel

delete will be restored.

Priority Channel Scan

If a priority channel (or two) has been assigned by your dealer or

communications coordinator, the priority channel will be checked

more often than the other channels in the scan list. If activity is

detected on a channel the radio will stop on that channel. While

stopped on a non-priority channel, the radio will continue to

check for activity on the priority channel. This is called priority

channel lookback, and the receive audio from the non-priority

channel will be briefly interrupted while priority lookback occurs.

While the radio is stopped on a non-priority channel it may be

deleted from the scan list by pressing a programmed Scan Skip

or Monitor function button. This is the nuisance channel delete

function. The priority channel can not be deleted from the scan

list. When the radio is turned off, all channels removed from the

scan list using nuisance channel delete will be restored.
