USING THE DELAY

FUNCTION

Many agencies use a two-way radio system that has a period of several seconds between a query and a reply. To avoid missing a reply, you can program a 2– second delay into any channel or frequency.

When your scanner stops on any channel or frequency with a programmed delay, DLY appears and the scanner continues to monitor that frequency for an additional 2 seconds after the transmission stops before resuming 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 continues scanning.

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

DELAY.

•If the scanner is searching, press DELAY. DLY appears and the scanner automatically adds a 2-second delay to every transmission it stops on in that band.

To turn off the delay, press DELAY while the scanner is monitoring the channel or frequency. DLY disappears.

LOCKING OUT CHANNELS AND FREQUENCIES

You can increase the scanning or search speed by locking out individual channels or frequencies that have a continuous transmission, such as a weather channel (see the “Weather Channel Frequency

Chart” on Page 19) or birdie frequency (see “Birdie Frequencies” on Page 22).

Locking Out Channels

To lock out a channel while scanning, press

and releasewhen the scanner stops on the channel.

To lock out a channel manually, select the channel then press and release

RVW) until L/O appears.

To unlock a channel, manually select that channel again, then press L/O (L/O RVW). L/ O disappears from the display.

Notes:

•The scanner automatically locks out empty channels.

•You can still manually tune to locked-out channels.

Locking Out Frequencies

To lock out a frequency during a service bank, or a direct search, press

when the scanner stops on the frequency. The scanner locks out the frequency then continues searching. You can lock out frequencies in both direct search and service bank searches.

Note: You can lock out as many as 50 frequencies during a search. If you try to lock out more, FLo -FULLappears (see “Reviewing Locked-Out Frequencies” on Page 21and “Removing All Locked-Out Tags From Frequencies” on Page 21).
