SPECIAL FEATURES

DELAY

Many agencies use a two-way radio system that might have a period of 2 or more seconds between a query and a reply. To keep from missing a reply, you can pro- gram a 2-second delay into any channel or frequency. The scanner continues to monitor the frequency for 2 seconds after the transmission stops before resuming scanning or searching.

To program a 2-second delay:

If the scanner is scanning channel-storage banks and stops on an active channel where you want to store a delay, quickly press DLY before it continues scanning again. DLY appears.

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

If the scanner is scanning service banks, press DLY while the scanner is scanning. DLY appears and the scanner automatically adds a 2-second delay to every transmission it stops on in that band.

To turn off the 2-second delay, press DLY while the scan- ner is monitoring the channel or scanning the service banks. DLY disappears from the display.
