SPECIAL FEATURES

DELAY

Many agencies use a two-way radio system that might have a pause of several seconds between a query and a reply. To avoid missing a reply, you can program a 2-second delay into any of your scanner’s channels. Then, when the scanner stops on the channel, DELAY appears and the scanner continues to monitor the channel for 2 seconds after the transmission stops before it re- sumes scanning.

You can program a 2-second delay in any of these ways:

•If the scanner is scanning and stops on an active channel, quickly press DLY before it starts to scan again.

•If the desired channel is not selected, manually select the channel then press DLY.

•If the scanner is searching, press DLY during the search.

DELAY appears and the scanner automatically adds a 2- second delay to every transmission it stops on.

To turn off the delay, press DLY when DELAY is displayed.

LOCKING OUT A CHANNEL

You can scan existing channels faster by locking out a channel that has a continuous transmission, such as a weather channel.

To lock out a channel, select the channel then press L-OUT. L/O appears.
