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
on a specific channel, you can pro-
gram a 2-second delay into any chan-
nel, or on frequencies during a
frequency search. The scanner con-
tinues to monitor the frequency for 2
seconds after the transmission stops
before resuming scanning.
To program a 2-second delay:
• If the scanner is scanning and
stops on an active channel,
quickly press 
DELAY before it con-
tinues scanning again.
• If the desired channel is not
selected, manually select the
channel, then press 
DELAY.
• If the scanner is searching, press
DELAY while the scanner is
searching. 
DLY appears on the
display and the scanner automati-
cally adds a 2-second delay to
every transmission it stops on.
To turn off the 2-second delay, press
DELAY while the scanner is monitoring
the channel or while the scanner is
searching. 
DLY disappears from the
display.
PRIORITY
The priority feature lets you scan
through channels and still not miss im-
portant or interesting calls on specific
channels. You can program one
stored channel in each bank as a pri-
ority channel (up to 10 stored chan-
nels). As the scanner scans the
banks, it checks the priority channels
every 2 seconds for activity.
Notes:
• You cannot use the priority and
data skip features at the same
time.
• You cannot use the priority and
count features at the same time.
• You can lock out priority channels.
If you lock out all priority channels,
the display shows 
LOC OUt when
you turn on the priority feature.
• The priority feature must be
turned off to listen to monitor
memories.
• The scanner checks the lowest-
numbered priority channels first. If
it detects a transmission on a pri-
ority channel, it stays on that
channel and does not check the
other priority channels until the
transmission ends.

USING THE COUNT 
FEATURE
The scanner can count the number of
times it has detected a transmission
on each channel since you turned on
the scanner or cleared the count.
1. While the scanner is scanning,
press 
MANUAL.
2. Press 
COUNT. The scanner dis-
plays 
COUNT, the current channel
number, and the count number.
3. Repeatedly press 
MANUAL to dis-
play each channel and the num-
ber of times the scanner detected
a transmission on that channel.
Note:

CHAN is on the display,
you can use the rotary tuner
instead of pressing 
MANUAL to
display the channel count.
While you view the count for a chan-
nel, you can zero the count by press-
ing 
CLEAR.
To turn off the count display, press
COUNT until COUNT disappears.
USING CTCSS
CTCSS is frequently used when two
different services or groups use the
same frequencies, but are relatively
close together. Each group sets their
transmitters to different CTCSS fre-
quencies, and sets their receivers to
only let them hear transmissions that
include the correct CTCSS frequency.This helps to avoid radio interference
between the groups.
You can use the CTCSS feature to
lock out undesired transmissions and
monitor only those which transmit a
specific CTCSS tone.
Note: 
You must install a CTCSS tone
board before you can use this feature.
