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 release

L/O (L/O RVW)

when the scanner

stops on the channel.

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

L/O (L/O

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

L/O (L/O RVW)

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

-FULL

appears (see

“Reviewing Locked-Out Frequencies” on
Page 21and “Removing All Locked-Out Tags
From Frequencies” on Page 21).
