FEATURES
Your new PSR-255 50-Channel Portable Scanner gives you
direct access to over 26,000 exciting frequencies, including
police and fire departments, ambulance services, and ama-
teur radio services. You can select up to 50 channels to scan,
and you can change your selection at any time.
The secret to your scanner's ability to scan so many frequen-
cies is its custom-designed microprocessor - a tiny, built-in
computer.
Your scanner has these special features:
Ten Preprogrammed Search Bands - let you search for
transmissions within preset frequency ranges, so you can
find interesting frequencies more quickly.
Fifty Channels - let you store up to 50 of your favorite fre-
quencies for easy recall and scanning.
Duplicate Frequency Check - automatically warns you if
you try to store a frequency you've already stored, to help
you use the scanner's memory more efficiently.
Monitor Memory - lets you temporarily save a frequency
located during a direct search, so you can move it to chan-
nel storage later.
Channel Lockout - keeps channels you select from being
scanned.
Memory Backup - keeps the channel frequencies stored in
memory for about 1 hour during a power loss.
Two-Second Scan Delay - delays scanning for 2 seconds
before moving to another channel, so you can hear more
replies.
Key Lock - lets you lock the keys to help prevent acciden-
tally changing the scanner's programming.
Flexible Antenna with BNC Connector - provides excellent
reception. The BNC connector makes it easy to attach and
remove the antenna or a variety of optional antennas.
Liquid Crystal Display - clearly displays how the scanner is
set and makes it easy to change those settings.
Three Power Options - you can power the scanner from
internal batteries (not supplied - including non-rechargeable
batteries, rechargeable batteries, or a rechargeable scanner
battery pack) or external AC or DC power (using optional
adapters).

Your PSR-255 scanner can receive all of these frequencies:
h26-54 MHz
h68-88 MHz
h137-174 MHz
h380-512 MHz
For a list of the frequency ranges in the ten preprogrammed
search bands, see "Search Bands".
We recommend you record your scanner's serial number
here. This number is on the scanner's back panel.

PREPARATION
POWER SOURCES
You can power your scanner from any of four sources:
hInternal batteries (not supplied) with the provided battery
holder
hA rechargeable scanner battery pack (not supplied)
hStandard AC power (using an optional AC adapter)
hVehicle battery power (using an optional DC cigarette-
lighter adapter)
You can power your scanner from six AA batteries. For the
longest operation and best performance, we recommend
alkaline batteries. You can also power the scanner using a
rechargeable scanner battery pack or rechargeable nickel-
cadmium batteries, and recharge it as you use the scanner.
Caution: Do not mix old and new batteries, different types of
batteries (standard, alkaline, or rechargeable), or recharge-
able batteries of different capacities.
Notes:
hThe PWR jack lets you connect an external AC or DC
adapter to operate the scanner. Connecting an adapter
to PWR disconnects the internal batteries. You can use
the PWR jack with either non-rechargeable or recharge-
able nickel-cadmium batteries installed.
hThe CHG jack lets you connect an external AC or DC
adapter to operate the scanner. The internal batteries re-
main connected when you connect an adapter to CHG,
and get recharged when you connect a charger.
Warning: Never use the CHG jack with non-rechargeable
batteries! If you try to recharge non-rechargeable batteries,
they could get very hot and explode.
Battery Install
1. Press down on the battery compartment cover on the bot-
tom of the scanner and slide the cover in the direction to
remove it.

5
2. Slide the battery holder out of the battery compartment.
3. If you are installing individual batteries, insert six AA bat-
teries in the battery holder as indicated by the polarity
symbols (+ and –) marked on the battery holder.
4. Slide the battery holder or battery pack into the compart-
ment.
Caution: The battery holder or battery pack fits only one
way inside the battery compartment. Do not force it.
5. Replace the cover.
When battery power is low, BATT flashes and the scanner
beeps about every 3 seconds. Immediately replace all six
non-rechargeable batteries or recharge the rechargeable
batteries or battery pack.
Caution: Always dispose of old batteries promptly and prop-
erly. Do not bury or burn them.
Using Standard AC Power
To power the scanner from AC power, you need an AC
adapter.
Cautions:
hYou must use an AC adapter that supplies 9 volts and
delivers at least 200 milliamps. Its center tip must be set
to negative, and its barrel plug must correctly fit the
scanner's PWR/CHG jack. The recommended adapter
meets these specifications. Using an adapter that does
not meet these specifications could damage the scanner
or the adapter.
hWhen you finish using the AC adapter, disconnect it from
the AC outlet first. Then disconnect it from the scanner.
Plug the adapter's barrel plug into the scanner's PWR jack.
Then plug the adapter's power module into a standard AC
outlet.
Using Vehicle Battery Power
To power the scanner from your vehicle's cigarette-lighter
socket, you need a DC adapter.

6
Cautions:
hYou must use a DC adapter that supplies 9 volts and de-
livers at least 200 milliamps. Its center tip must be set to
negative, and its plug must correctly fit the scanner's PWR/
CHG jack. The recommended adapter meets these speci-
fications. Using an adapter that does not meet these speci-
fications could damage the scanner or the adapter.
hTo protect your vehicle's electrical system, always plug
the adapter into the scanner before you plug it into your
vehicle's cigarette-lighter socket. Always unplug the
adapter from the vehicle's cigarette-lighter socket before
you unplug it from the scanner.
Plug the adapter's barrel plug into the scanner's PWR jack.
Then plug the adapter's power module into your vehicle's
cigarette-lighter socket.
Charging a Rechargeable Battery Pack/
Rechargeable Batteries
Your scanner has a built-in charging circuit that lets you
charge a rechargeable battery pack or rechargeable nickel-
cadmium batteries while it is in the scanner. To charge it,
simply connect an AC or DC adapter to the scanner's CHG
jack.
It takes about 14-16 hours to recharge a battery pack (re-
chargeable batteries) that is fully discharged. You can oper-
ate the scanner while recharging the battery pack (recharge-
able batteries), but charging takes longer.
Note: A rechargeable battery pack (rechargeable batteries)
lasts longer if you let it fully discharge once a month. To do
this, simply use the scanner until BATT flashes and the scan-
ner beeps about every 3 seconds. Then fully charge it.
Important! At the end of a rechargeable battery pack or bat-
teries useful life, it must be recycled or disposed of properly.
Contact your local, county, or state hazardous waste man-
agement authorities for information on recycling or disposal
programs in your area. Some options that might be avail-
able are: municipal curb-side collection, drop-off boxes a
retailers such as your local store, recycling collection cen-
ters, and mailback programs.

CONNECTING THE ANTENNA
Follow these steps to attach the supplied flexible antenna to
your scanner.
1 Align the slots around the scanner's connector with the
tabs on the ANT jack.
2. Press the antenna down over the jack and turn the
antenna's base clockwise until it locks into place.
Connecting an Optional Antenna
The ANT jack on the top of the scanner makes it easy to use
the scanner with a variety of antennas. Instead of the sup-
plied antenna, you can attach a different one, such as an
external mobile antenna or outdoor base station antenna.
Follow the installation instructions supplied with the antenna,
route the antenna cable to the scanner, then connect it to the
ANT jack.
Warning: Use extreme caution when installing or removing
an outdoor base station antenna. If the antenna starts to fall,
let it go! It could contact overhead power lines, if the an-
tenna touches a power line, contact with the antenna, mast,
cable or guy wires can cause electrocution and death! Call
the power company to remove the antenna. Do not attempt
to do so yourself.
USING THE BELT CLIP
You can use the belt clip for hands-free carrying when you
are on the go. Simply slide the belt clip over your belt or
waistband.
CONNECTING AN EARPHONE/
HEADPHONES
For private listening, you can plug an earphone or mono
headphones with a 3.5 mm plug into the PHONE jack on top
of your scanner. This disconnects the internal speaker.
Caution: To protect your hearing, follow these guidelines
when you use an earphone or headphones:

8
hDo not listen at extremely high volume levels. Ex-
tended high-volume listening can lead to perma-
nent hearing loss.
hOnce you set the volume, do not increase it. Over
time, your ears adapt to the volume level, so a vol-
ume level that does not cause discomfort might still
damage your hearing.
Warning: Do not use an earphone or headphones with
your scanner when operating a motor vehicle or riding
a bicycle, in or near traffic. Doing so can create a traf-
fic hazard and could be illegal in some areas.
CONNECTING AN EXTENSION
SPEAKER
In a noisy area, an extension speaker or an amplified
speaker might provide more comfortable listening.
Plug the speaker cable's 3.5 mm plug into your
scanner's PHONE jack.
