3.Press MON/CLEAR and enter the number of the monitor memory that contains the frequency you want to store.

4.Press E. The scanner stores the frequency into the selected channel.

SCANNING THE STORED

CHANNELS

To begin scanning channels, press SCAN. The scanner scans through all non-locked channels in the activated banks. (See “Locking Out Channels” on Page 34 and “Turning Channel-Storage Banks On and Off” on Page 33). When the scanner finds a transmission, it stops on it. When the transmission ends, the scanner resumes scanning.

Notes:

If you have not stored frequencies into any chan- nels, the scanner does not scan.

If the scanner picks up unwanted, partial, or very weak transmissions, turn SQUELCH clockwise to decrease the scanner's sensitivity to these signals. If you want to listen to a weak or distant station, turn SQUELCH counterclockwise.

If SQUELCH is adjusted so you always hear a hiss- ing sound, the scanner does not scan properly.

To scan in the trunk tracking mode, see “Scanning a Trunked Bank” on Page 43.

MANUALLY SELECTING A

CHANNEL

You can continuously monitor a single channel without scanning. This is useful if you hear an emergency broadcast on a channel and do not want to miss any details — even though there might be periods of silence

— or if you want to monitor a specific channel.

Follow these steps to manually select a channel.

1.Press MAN.

2.Enter the channel number.

3.Press MAN again.
