Locking Out Channels

You can increase the effective scanning speed by locking out individual channels that have a continuous transmission, such as a weather chan- nel. To lock out a channel, manually select the channel and press L- OUT/S/S so L appears on the display.

Notes:

You can still manually select locked out channels.

You cannot lock out all channels.

To remove the lock-out from a channel, manually select the channel and press L-OUT/S/Sso L disappears from the display.

To remove the lock-out from all channels, press MANUAL, then press and hold L-OUT/S/Suntil the scanner beeps twice (about 3 seconds).

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 si- lence — or if you want to monitor a specific channel.

Follow these steps to manually select a channel.

1.Press MANUAL.

2.Enter the channel number.

3.Press MANUAL again.

Or, if your scanner is scanning and stops at the desired channel, press MANUAL one time. (Pressing MANUAL additional times causes your scanner to step through the channels.)

To resume automatic scanning, press SCAN. Your scanner then scans through all non-locked channels.
