Note: If you turned the key tone off (see “Turning the Key Tone On or Off” on Page 21), the scanner does not beep when you hold down S/S-LOCKOUT.

Removing Lockout from Channels

Follow these steps to remove the lock- out from a channel while scanning.

1.Press MANUAL to stop scanning.

2.Use the number keys to enter the channel number you want to delete the lockout from.

3.Press MANUAL.

4.Repeatedly press LOCKOUT until L/O disappears.

To remove the lockout from all channels while scanning, use the number keys to select the banks containing the skipped channels, press MANUAL, then hold down LOCKOUT until the scanner beeps twice.

Note: If you turned off the key tone (see “Turning the Key Tone On or Off” on Page 21), the scanner does not beep when you hold down LOCKOUT.

PRIORITY

The priority feature lets you scan through programmed channels and still not miss important or interesting calls on specific channels. You can program one stored channel in each bank as a priority channel (up to 10 total). As the scanner

scans, it checks the priority channels in each selected bank for activity every 2 seconds.

Notes:

•You can skip priority channels. If you skip all priority channels, the scan- ner displays P CH LOC OUt when you turn on the priority feature. See “Skipping Frequencies/Channels” on Page 19.

•The priority feature must be turned off to listen to monitor memories.

The scanner automatically designates the first channel in each bank as that bank’s priority channel. Follow these steps to program a different channel as the priority channel.

1.Press PROGRAM.

2.Use the number keys to enter the channel number you want to pro- gram as the priority channel, then press PRIORITY. P appears to the right of the channel number.

3.Repeat Steps 1 and 2 for each channel you want to program as a priority channel.

To review the priority channel numbers for all banks, press PROGRAM then re- peatedly press PRIORITY.

To turn on priority, press PRIORITY dur- ing scanning or when MAN appears. PRI appears, and the scanner checks the priority channel in each selected bank every 2 seconds. It stays on the channel if there is activity, and P ap- pears.
