Searching for Frequencies

During a tune search, the scanner tunes up or down
starting from a frequency you specify.
1. Press TUNE. The display alternates between PSE
and –t–.
2. If you want to change the starting frequency, enter a
new frequency and press ENT.
3. Press PSE to start tune search. –t– appears on the
display.

Service Bank Search

Your scanner contains groups of preset frequencies
called Service Banks. You can search for marine, fire/
police, aircraft, ham, FM, and weather transmissions even
if you do not know the specific frequencies that are used
in your area.
Then you can store the frequencies you find into the
scanner's channels (except for weather and marine
banks, which are already stored as channels). To start a
search, press the button of the Service Bank you would
like to search ( Marine, Fire/Police, Aircraft, Ham, FM, or
Weather).
Search Commands
• Press PSE to pause searching. Press PSE again to
resume.
• Press •/Delay to turn the two-second delay
feature on and off.
• Press L/O to lock-out a frequency (except
Weather band).
• To reverse the search direction at any time, press
 or .
• If necessary, you can select search groups using
the number keys.

Storing Found Frequencies

Once you find interesting frequencies during a Tune or
Service Bank search, you can store them in the scanner's
channel-storage banks.
1. Press ENT when you find a frequency. The bank
number and StorE appear.
2. To change banks, enter the new bank number.
3. Press ENT to store the frequency. The channel and
frequency flash twice. To cancel the operation, press
TUNE/CLEAR.
• The frequency is automatically stored in the first empty
channel of the selected bank.
• If the scanner displays -dUPL-, the frequency is already
stored in another channel. Press ENT if you want to
continue storing the frequency. Press TUNE/CLEAR
to cancel.
• If there are no empty channels in the bank, Ch-FULL
appears. You can select another bank or clear some
channels in the current bank (see "Clearing a Stored
Channel" on page 19).
• If the scanner displays -dUPL- or CH-FULL, you can
store another channel location by pressing PGM. The
channel number flashes and 000.0000 (or previous
frequency) appears. Press the desired channel number
then press ENT. Repeat if needed. Press ENT again
when an empty channel is found.

Birdie Frequencies

All scanners have birdie frequencies, which are signals
created inside a scanner that can cause interference.
To find the birdies in your scanner:
1. Disconnect the antenna, and make sure that no
other nearby radio or TV sets are turned on near the
scanner.
2. Search every frequency range from its lowest
frequency to the highest. Occasionally, the
searching will stop as if it has found a signal, often
without any sound. This is a birdie.
3. Make a list of all the birdies in your scanner for
future reference.
