About Your Scanner
Understanding Banks
Service Banks
The scanner is preprogrammed with all the 
frequencies allocated to the weather, ham, marine, 
aircraft, police, and fire services.
Channel-Storage Banks
To make it easier to identify and select the channels 
you want to listen to, the 100 channels are divided 
into 10 channel-storage banks. Each bank has 10 
channels. Use each channel-storage bank to group 
frequencies, such as those for the police 
department, fire department, ambulance services, or 
aircraft.
For example, the police department might use four 
frequencies in your town while the fire department 
uses an additional four. You could program the four 
police frequencies starting with Channel 1 (the first 
channel in bank 1), and program the fire department 
frequencies starting with Channel 11 (the first 
channel in bank 2).

Operation
Operation
Turning On The Scanner and 
Setting Squelch
Note: Make sure the scanners antenna is 
connected before you turn it on.
1. Turn Squelch fully counterclockwise.
2. Press and hold   for about 2 seconds to turn 
the scanner on, then turn Vo l u m e clockwise until 
you hear a hissing sound.
3. If the scanner is scanning, press Hold to stop 
scanning, then turn Squelch clockwise until the 
hissing stops.
Storing Known Frequencies 
Into Channels
1. Press Hold. Then enter the channel number 
where you want to store a frequency, then press 
Func and Pgm. The channel number appears.
2. Use the number keys and   to enter the 
frequency (including the decimal point) you want 
to store.
3. Press E to store the frequency into the channel.
Notes:
• If you entered an invalid frequency in Step 2, 
Error appears and the scanner beeps three 
times. Enter a valid frequency.
• The scanner automatically rounds the entered 
number to the nearest valid frequency.
For example, if you enter 151.473 (MHz), your 
scanner accepts it as 151.475.
• When you enter a frequency into a channel, the 
scanner automatically turns on the delay 
function and DLY appears. When delay is turned 
on, the scanner automatically pauses scanning

Operation
2 seconds after the end of a transmission before 
scanning proceeds to the next channel. To turn 
the function off or on, press Func + Dly.
• If you enter a frequency that has already been 
entered elsewhere, the scanner sounds an error 
tone and displays the channel that was 
duplicated. If you entered the frequency by mis-
take, press   then enter the correct frequency. 
To enter the frequency anyway, press E to 
accept.
4. To program the next channel in sequence, press 
E then repeat Steps 2 and 3.
Searching For and Temporarily 
Storing Active Frequencies
If you do not have a reference to frequencies in your 
area, use a search (except weather service search) 
to find a transmission.
Note: When the scanner starts searching, it auto-
matically turns on the delay function. To turn delay 
on or off, press Func + Dly.
Service Search
You can search for weather, ham, marine, aircraft, 
police, or fire transmissions without knowing the 
specific frequencies used in your area. The scanner 
is preprogrammed with all the frequencies allocated 
to these services. To use this feature, press Func 
and Svc. SRCH appears and the scanner searches 
starting with the weather service bank. To select a 
different service bank, repeatedly press Func and 
Svc. Service mode appears on the display.
When the scanner stops on a transmission, press 
Hold to stop searching and listen to the 
transmission. Hold appears. In this mode, you can

Operation
press Func +   or Func +   to step through the 
frequencies.
To release the hold and continue searching, press 
Hold. Or, if you did not press Hold, simply press 
Func +   or Func +   to continue searching.
Note: Because there are many different frequencies 
allocated to fire and police departments, it can take 
several minutes to search all the service frequencies.
Storing Frequencies into Channels 
During Service Search
You can store frequencies you found during service 
search or service search hold mode into channels.
1. Press Func and Pgm during service search or 
service search hold mode. The frequency and 
the lowest blank channel alternately appear.
2. Press E to store the frequency into the blank 
channel. If you want to select another channel, 
press Func +   or Func +   before you press 
E. You can also use the 0-9 key to select the 
bank.
If you entered a frequency that has already been 
entered elsewhere, the scanner sounds an error 
tone and displays the channel that was duplicated. 
If you entered the frequency by mistake, press   
then enter the correct frequency. To enter the 
frequency anyway, press E to accept.
Scanning the Stored Channels
To begin scanning channels, press Scan. 
The scanner scans through all non-locked channels 
in the activated banks. (See “Locking Out Channels” 
on Page 48 and “Turning Channel-Storage Banks 
On and Off” on Page 47). When the scanner finds a

Operation
transmission, it stops on it. When the transmission 
ends, the scanner resumes scanning.
Notes:
• If you have not stored frequencies into any 
channels, the scanner does not scan.
• If the scanner picks up unwanted partial, or very 
weak transmissions, turn Squelch clockwise to 
decrease the scanners sensitivity to these 
signals. To listen to a weak or distant station, 
turn Squelch counterclockwise.
• To ensure proper scanning, adjust Squelch until 
the audio mutes.
Manually Selecting a Channel
You can continuously monitor a single channel 
without scanning. This is useful if you hear an 
emergency broadcast on a channel and do not want 
to miss any details - even though there might be 
periods of silence - or if you want to monitor a 
specific channel.
To manually select a channel, press Hold, enter the 
channel number then press Hold again.
Or, during scanning, if the radio stops at a channel 
you want to listen to, press Hold once. (Repeatedly 
pressing Hold at this time causes the scanner to 
step through the channels.) Press Scan to resume 
automatic scanning.

Special Features
Close CallTM RF Capture Technology
Your scanners Close Call feature lets you set the 
scanner so it detects then displays the frequency of 
a nearby strong radio transmission. Close Call RF 
capture works great for finding frequencies at 
venues such as malls and sporting events. You can 
set the scanner so Close Call detection works in the 
background while you are scanning other 
frequencies, turn off normal scanning while Close 
Call is working, or turn off the Close Call feature and 
use the scanner normally. You can set the scanner 
so it alerts you when the Close Call feature detects a 
frequency. You can also set the frequency band 
where you want the scanner to look for 
transmissions.
Unlike searching, which requires the scanner to tune 
to a frequency to check for a transmission, Close 
Call RF capture directly detects the presence of a 
strong, nearby signal and instantly tunes to the 
source’s frequency.
Notes: 
• Close Call RF capture works well for locating the 
source of strong local transmissions such as 
mobile and handheld two-way radios in areas 
with no other strong transmission sources. 
However, if you are in an area with many 
transmission sources (such as pager radio
transmitters, multi-use radio towers, traffic 
control devices, etc.), Close Call RF capture 
might not find the transmission you are 
searching for, or it might find a transmission 
other than the one you are searching for.
• Close Call RF capture cannot detect satellite 
dishes or any transmitter with a frequency above 
or below the frequency ranges listed under 
“Setting the Close Call Options” on Page 38.

Special Features
• Close Call works better with some types of 
transmissions than others. It might not correctly 
display frequency information for transmitters 
using a highly directive antenna (such as an 
amateur radio beam antenna), if there are many 
transmitters operating at the same time in the 
same area, or if the transmitter is a broadcast 
television station.
