SPECIAL FEATURES
DELAY
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 a channel
or frequency with a programmed delay,
DLY appears and the
scanner continues to monitor that frequency for 2 seconds af-
ter 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 resumes 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 2-second delay in a channel or frequency, press
DELAY/ •
while the scanner is monitoring that channel or fre-
quency. DLY disappears.
LOCKING OUT CHANNELS OR
FREQUENCIES
You can increase the effective scanning or search speed by
locking out individual channels or frequencies that have a con-
tinuous transmission, such as a weather channel (see “Nation-
al Weather Frequencies” on Page 52) or a birdie frequency
(see “Birdie Frequencies” on Page 52).
Locking Out Channels
To lock out a channel during scanning, press L/O/L/O RVW
when the scanner stops on the channel.
To manually lock out a channel, select the channel then press
L/O/L/O RVW . L/O appears.
