MANUALLY SELECTING A CHANNEL

You can continuously monitor a specific channel without scanning. This is useful if you hear an emergency broadcast on a channel and want to hear all the de- tails (even though there might be peri- ods of silence) or if you want to monitor only a specific channel or a locked-out channel.

Follow these steps to manually select a channel.

1.Press MANUAL.

2.Use the number keys to enter the desired channel number, then press

MANUAL again.

Notes:

•If your scanner is scanning and stops at the desired channel, simply press MANUAL to manually select the channel.

•If you repeatedly press MANUAL, the scanner steps through the chan- nels.
