USING THE 2-SECOND 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 or frequencies. Then, when the scan- ner stops on the channel or frequen- cy, DELAY appears and the scanner continues to monitor the channel/fre- quency for 2 seconds after the trans- mission stops before it resumes scanning or searching.

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 DELAY before it starts to scan again. DELAY appears.

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

•If the scanner is searching, press DELAY during the search. DELAY appears and the scan- ner automatically adds a 2-sec- ond delay to every transmission it stops on.

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

LOCKING OUT

CHANNELS

You can set your scanner to scan more efficiently by locking out chan- nels you do not want to monitor. This is handy for locking out channels where you stored a frequency with a continuous transmission, such as a weather channel.

To lock out a channel, press MANU- AL, enter the desired channel num- ber, press MANUAL or PGM to select the channel, then press L/O/SEARCH SKIP so LOCKOUT appears.

Note: You can still manually select locked out channels.
