INTRODUCTION
Your new 200 Channel VHF/Air/UHF Handheld Scanner
lets you scan conventional transmissions, and is
preprogrammed with search banks for convenience. By
pressing a one touch search key, you can quickly search
those frequencies most commonly used by public ser-
vice and other agencies without tedious and complicated
programming
This scanner gives you direct access to over 25,000 ex-
citing frequencies, including those used by aircraft and
amateur radio services, and you can change your selec-
tion at any time.
Your scanner also has these special features:
Liquid-Crystal Display—makes it easy to view and
change programming information. The display backlight
also makes the scanner easy to read in low-light situa-
tions.
One-Touch Search Banks—let you search preset fre-
quencies in separate band 1–4, and ham bands, to make
it easy to locate specific types of calls.
Priority Channel—lets you program a channel as the pri-
ority channel. As the scanner scans, it checks the priority
channel every 2 seconds so you do not miss transmis-
sions on that channel.
Tune—lets you tune for new and unlisted frequencies
starting from a specified frequency.
Ten Channel-Storage Banks—you can store 20 chan-
nels in each bank (200 total channels), letting you group
channels so you can more easily identify calls.
High Speed Search and High Speed Scan—lets you
set the scanner to search at up to 50 steps per second (in
frequency bands with 5 kHz steps) and scan at up to 25
channels per second, to help you quickly find interesting
broadcasts.
Lockout Function—lets you set your scanner to skip over
specified channels or frequencies when scanning or
searching.
Memory Backup—keeps the channel frequencies stored
in memory for about an hour in the event of a power loss.
Scan Delay—delays scanning for about 2 seconds be-
fore moving to another channel, so you can hear more
replies that are transmitted on the same channel.

Duplicate Channel Alert—warns you when the frequency
you are storing already exists in memory.
Key Lock—lets you lock the scanner’s keys to prevent
accidentally changing the scanner’s programming.
Three Power Options—you can power the scanner from
internal (rechargeable or non-rechargeable batteries) or
external AC or DC power (using an optional AC or DC
adapter).
Your PSR-282 scanner can receive these bands:
66–88 MHz 118–136.9916 MHz
137–174 MHz 380–512 MHz

PREPARATION
You can power your scanner from any of three sources:
Note: Connecting an AC or DC adapter to the scanner
disconnects internal batteries when you use the supplied
non-rechargeable battery holder (black), but it does not
disconnect internal batteries when you use the supplied
rechargeable battery holder (yellow).
• internal non-rechargeable batteries or rechargeable
batteries (not supplied—see “Installing Batteries”).
• standard AC power (with an optional AC adapter—
see “Using AC Power” on Page 6).
• Vehicle power (with an optional DC adapter—see “Us-
ing Vehicle Battery Power” on Page 6).
Installing Batteries
Your scanner uses four AA batteries (not supplied) for
power. You can use either the supplied non-rechargeable
battery holder (black), or the supplied rechargeable bat-
tery holder (yellow) to install the batteries.
Warning: Never install non-rechargeable batteries in the
rechargeable yellow battery holder. Non-rechargeable
batteries can get hot or explode if you try to recharge
them.
If you install the rechargeable battery holder, you can
operate the scanner and recharge the rechargeable bat-
teries at the same time. See “Charging Rechargeable
Batteries” on Page 5.
Warning:
• The battery holder fits only one way. Do not force it.
• Use only fresh batteries of the required size and rec-
ommended type.
• Do not mix old and new batteries, different types of
batteries (standard, alkaline, or rechargeable), or re-
chargeable batteries of different capacities.
Follow these steps to install batteries.
1. Press in on the battery compartment cover on the back
of the scanner and slide the cover down to remove it.
2. Pull the battery holder out of the battery compartment.

3. If you are using non-rechargeable batteries, place them
into the black holder, as indicated by the polarity sym-
bols (+ and –) marked on the holder. Or, if you are
using rechargeable batteries, place them into the yel-
low holder, as indicated by the polarity symbols (+
and –) marked on the holder.
4. Place the battery holder into the battery compartment.
5. Replace the cover.
When Bappears and the scanner beeps or the scanner
stops operating properly, replace or recharge the batter-
ies.
Warning: Dispose of old batteries promptly and prop-
erly. Do not burn or bury them.
Caution: If you do not plan to use the scanner with bat-
teries for a month or more, remove the batteries. Batter-
ies can leak chemicals that can destroy electronic parts.
If the scanner stops working properly after connecting it
to power, try resetting it. See “Resetting the Scanner” on
Page 23.
Note: You must charge rechargeable batteries before you
use them the first time. See “Charging Rechargeable
Batteries.”
Charging Rechargeable Batteries
Your scanner has a built-in charging circuit that lets you
charge nickel-metal hydride (Ni-MH) or nickel cadmium
(Ni-CD) rechargeable batteries (not supplied) while they
are in the scanner. To charge rechargeable batteries, you
need to use a 9V AC adapter or 10V DC adapter with
4.7mm outer/1.7mm inner plug.
Cautions:
• You must use an adapter that supplies 9V DC and de-
livers at least 300mA. Its center tip must be set to posi-
tive and its plug must fit the scanner’s PWR DC 9V
jack. Using an adapter that does not meet these speci-
fications could damage the scanner or the adapter.
• Always connect the AC adapter to the scanner before
you connect it to AC power. When you finish, discon-
nect the adapter from AC power before you discon-
nect it from the scanner.
Note: It takes about 15 hours to recharge fully discharged
1500mAh Ni-MH rechargeable batteries. You can oper-
ate the scanner while recharging the rechargeable bat-
teries, but charging takes longer.
Manual01.p65 2003/03/11, 15:46Page 5 AdobePageMaker6.5J/Win
6
Connect 4.7mm outer/1.7mm inner plug to the scanner’s
PWR DC 9V jack.
Note: When you charge Ni-CD batteries, pay attention
not to over charge. Overcharging shortens battery life.
The scanner can also charge Ni-Cd batteries. 600mAh
batteries require 6 hours and 850 mAh batteries require
8 hours to charge.
Rechargeable batteries last longer and deliver more
power if you let them fully discharge once a month. To do
this, use the scanner until B appears. Then fully charge
the rechargeable batteries.
Using AC Power
You can power the scanner using a 9V, 300mA AC adapter
with 4.7mm outer/1.7mm inner plug.
Cautions:
• You must use an adapter that supplies 9V DC and de-
livers at least 300 mA. Its center tip must be set to
positive and its plug must fit the scanner’s PWR DC
9V jack. Using an adapter that does not meet these
specifications could damage the scanner or the
adapter.
• Always connect the AC adapter to the scanner before
you connect it to AC power. When you finish, discon-
nect the adapter from AC power before you discon-
nect it from the scanner.
To power the scanner using an AC adapter, insert the
plug (4.7mm outer/1.7mm inner plug) into the scanner’s
PWR DC 9V jack. Then connect the other end of the
adapter to a standard AC outlet.
Using Vehicle Battery Power
You can also power the scanner from a vehicle’s 12V
power source (such as a cigarette-lighter socket) using a
9V, 300mA adapter with 4.7mm outer/1.7mm inner plug.
Caution: Always connect the DC adapter to the scanner
before you connect it to the power source. When you
finish, disconnect the adapter from the power source
before you disconnect it from the scanner.
To power the scanner using a DC adapter, set the
adapter’s voltage switch to 9V. Next, insert the plug
(4.7mm outer/1.7mm inner plug) into the scanner’s PWR
DC 9V jack. Plug the other end of the DC adapter into
your vehicle’s cigarette-lighter socket.

Note: If you use a cigarette-lighter power cable and your
vehicle’s engine is running, you might hear electrical noise
from the engine while scanning. This is normal.
Connecting the Supplied Antenna
To attach the supplied flexible antenna to the ANT jack
on top of your scanner, align the slots around the
antenna’s connector with the tabs on the ANT jack. Press
the antenna down over the jack and turn the antenna’s
base clockwise until it locks into place.
Connecting an Outdoor Antenna
The antenna connector on your scanner makes it easy to
use the scanner with a variety of antennas, such as an
external mobile antenna or outdoor base station antenna.
Always use 50 Ohm coaxial cable, such as RG-58 or RG-
8, to connect an outdoor antenna. For lengths over 50
feet, use RG-8 low-loss dielectric coaxial cable. If the an-
tenna cable’s connector does not have a BNC connec-
tor, you will also need a BNC adapter.
Follow the installation instructions supplied with the an-
tenna, route the antenna cable to the scanner, then con-
nect it to the ANT jack.
Connecting an Earphone/Headphones
For private listening, you can plug a 3.5 mm mini-plug
earphone or headphones (not supplied), into jack on
the top of the scanner. This automatically disconnects
the internal speaker.
Listening Safely
To protect your hearing, follow these guidelines when you
use an earphone or headphones.
• Set the volume to the lowest setting before you begin
listening. After you begin listening, adjust the volume
to a comfortable level.
• Do not listen at extremely high volume levels. Extended
high-volume listening can lead to permanent hearing
loss.
• Once you set the volume, do not increase it. Over time,
your ears adapt to the volume level, so a volume level
that does not cause discomfort might still damage your
hearing.

Traffic Safety
Do not use an earphone or headphones with your scan-
ner when operating a motor vehicle or riding a bicycle in
or near traffic. Doing so can create a traffic hazard and
could be illegal in some areas.
If you use an earphone or headphones with your scan-
ner while riding a bicycle, be very careful. Do not listen to
a continuous broadcast. Even though some earphones/
headphones let you hear some outside sounds when lis-
tening at normal volume levels, they still can present a
traffic hazard.
Connecting an Extension Speaker
In a noisy area, an amplified extension speaker (not sup-
plied), might provide more comfortable listening. Plug
the speaker cable’s 3.5 mm mini-plug into jack.
Note: You must use an amplified speaker with this scan-
ner. Non-amplified speakers do not provide sufficient
volume for comfortable listening.
Using the Belt Clip
You can use the belt clip attached to the back of the scan-
ner for hands-free carrying when you are on the go. Slide
the belt clip over your belt or waistband.

ABOUT YOUR SCANNER
Once you understand a few simple terms used in this
manual and familiarize yourself with your scanner’s fea-
tures, you can put the scanner to work for you. You sim-
ply determine the type of communications you want to
receive, then set the scanner to scan them.
A frequency is the receiving signal location (expressed in
kHz or MHz). To find active frequencies, you can use the
search function.
You can also search the One Touch Search Banks, which
are preset groups of frequencies categorized by type of
service.
When you find a frequency, you can store it into a pro-
grammable memory location called a channel, which is
grouped with other channels in a channel-storage bank.
You can then scan the channel-storage banks to see if
there is activity on the frequencies stored there. Each time
the scanner finds an active frequency, it stays on that
channel until the transmission ends.
