POWERING THE CD PLAYER
You can power your CD player from any
of these sources:
Follow these steps to install the batter-
ies.
• two AA alkaline batteries (not sup-
plied)
• two rechargeable AA nickel-
cadmium batteries (not supplied)
• vehicle battery power using the sup-
plied DC adapter
• standard AC power using an AC
adapter (not supplied)
1. Press down on the battery compart-
ment cover and slide it in the direc-
tion of the arrow on the cover, then
lift the cover.
Note: The CD player senses whether or
not the batteries you install are rechar-
gables, and turns on the charging circuit
or disconnects the batteries accordingly.
Caution: The battery compartment
cover is attached to the CD player.
Do not try to remove it.
2. Put two AA alkaline batteries or two
AA nickel-cadmium batteries in the
battery compartment, as indicated
by the polarity symbols (+ and –)
marked inside.
USING BATTERIES
You can power your CD player from two
AA alkaline batteries (such as Ra-
dioShack Cat. No. 23-552) or two re-
chargeable AA nickel-cadmium bat-
teries (such as Cat. No. 23-125).
Note: Before you use the CD player
with nickel-cadmium batteries, you
need to charge them, either in an
external battery charger (such as
Cat. No. 23-134) or in the CD player
(see “Recharging Nickel-Cadmium
Batteries” on Page 7).
Cautions:
• Always use fresh, or freshly
charged, batteries of the required
size and recommended type.
• Do not mix old and new batteries,
different types of batteries (stan-
dard, alkaline, or rechargeable
nickel-cadmium), or rechargeable
batteries of different capacities.
3. Close the battery compartment
cover.
When
flashes on the display, the
sound distorts, or the volume weakens,
replace or recharge the batteries.
6
42-5080.fm Page 7 Thursday, August 12, 1999 1:25 PM
Cautions:
Follow these steps to charge nickel-
cadmium batteries in the CD player.
• If you will not be using the CD player
with battery power for more than a
month, or if you plan to use only AC
or DC power, remove the batteries.
1. Connect an AC adapter or the sup-
plied DC adapter to your CD player
(see “Using AC Power” on Page 9
or “Using Vehicle Battery Power” on
Page 8).
• Dispose of old batteries promptly
and properly.
2. With rechargeable batteries in-
stalled and the CD compartment

CHG flashes on the display. Then
CHG CHG CHG appears and the CD
player starts to recharge the batter-
ies.
If you connect the supplied DC adapter
(see “Using Vehicle Battery Power” on
Page 8) or an AC adapter (see “Using
AC Power” on Page 9) to the CD player,
you can set the CD player to charge
nickel-cadmium batteries while they are
inside the CD player’s battery compart-
ment.
It takes about 3 hours to charge
new or fully discharged nickel-
cadmium batteries. Subsequent
charges take 2–3 hours.
Cautions:
• Use only the supplied DC adapter or
an AC adapter that meets the speci-
fications in “Using AC Power” on
Page 9 to recharge the batteries in
the CD player. Other adapters could
damage your CD player or the bat-
teries.
Note: During recharging, the auto
power on/off feature is disabled.
3. When the batteries are fully
charged, the CD player automati-
cally stops charging them and turns
off. Disconnect the AC or DC
adapter.
• Do not use the CD player or open
the CD compartment cover while
you are charging nickel-cadmium
batteries.
• Nickel-cadmium batteries charge
more efficiently if the temperature is
above 40°F (4.5°C) and below 90°F
(32°C).

42-5080.fm Page 8 Thursday, August 12, 1999 1:25 PM
Important: Your CD player is capable of
using nickel-cadmium batteries. At the
end of the batteries’ useful life, they
must be recycled or disposed of proper-
ly. Contact your local, county, or state
hazardous waste management authori-
ties for information on recycling or dis-
posal programs in your area. Some
options that might be available are: mu-
nicipal curbside collection, drop-off box-
es at retailers such as your local
RadioShack store, recycling collection
centers, and mail-back programs.
Follow these steps to connect the CD
player to your vehicle’s battery power.
1. Insert the DC adapter’s barrel plug
DC IN 6V
into the CD player’s
jack.
2. Make sure the DC adapter’s tip is
screwed in tightly, then plug the DC
adapter’s other end into your vehi-
cle’s cigarette-lighter socket.
USING VEHICLE BATTERY
POWER
Note: If the CD player does not operate
when you use the DC adapter, unplug
the cord from the cigarette-lighter socket
and clean any ashes or debris from the
socket.
You can power the CD player from your
vehicle’s battery power with the supplied
DC adapter.
Cautions:
• The supplied DC adapter supplies 6
volts and delivers at least 500 milli-
amps. Its center tip is set to positive,
and its plug correctly fits the CD
DC IN 6V
player’s
jack. Using a DC
adapter that does not meet these
specifications could damage the CD
player or the DC adapter.
• When you finish using the CD
player, always unplug the DC
adapter from the cigarette-lighter
socket before you disconnect it from
your CD player.

USING AC POWER
You can power the CD player from a
standard AC outlet using an optional AC
adapter such as Cat. No. 273-1664.
Cautions:
• You must use an AC adapter that
supplies 6 volts and delivers at least
500 milliamps. Its center tip must be

CONNECTIONS
You can listen to your CD player by con-
necting earphones/headphones or am-
plified speakers to the player’s PHONES
jack, or by connecting a home audio or
autosound system to the CD player’s
LINE OUT jack.
Listening Safely
To protect your hearing, follow these
guidelines when you use earphones or
headphones.
• Set the volume to the lowest setting
before you begin listening. After you
begin listening, adjust the volume to
a comfortable level.
Note: If the jacks on your equipment do
not match the plugs on the supplied Y-
cable, check with your local RadioShack
store for the proper cable adapter.
• Do not listen at extremely high vol-
ume levels. Extended high-volume
listening can lead to permanent
hearing loss.
CONNECTING
EARPHONES/
HEADPHONES
• Once 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 dis-
comfort might still damage your
hearing.
For private listening, you can plug a pair
of stereo earphones or headphones with
1
a /8-inch plug (not supplied) into the
PHONES jack on the CD player.
Traffic Safety
Do not wear earphones or headphones
while operating a motor vehicle or riding
a bicycle. This can create a traffic haz-
ard and could be illegal in some areas.
Even though some earphones and
headphones let you hear some outside
sounds when listening at normal volume
levels, they still can present a traffic haz-
ard.
Your local RadioShack carries a wide
variety of earphones and headphones to
use with your CD player.

sign and craftsmanship. The following suggestions will help you care for your CD play-
er so you can enjoy it for years.
Keep the CD player dry. If it gets wet, wipe it dry immediately. Liquids
might contain minerals that can corrode the electronic circuits.
Use and store the CD player only in normal temperature environments.
Temperature extremes can shorten the life of electronic devices, dam-
age batteries, and distort or melt plastic parts.
Keep the CD player away from dust and dirt, which can cause prema-
ture wear of parts.
Handle the CD player gently and carefully. Dropping it can damage cir-
cuit boards and cases and can cause the CD player to work improperly.
Use only fresh batteries of the required size and recommended type.
Batteries can leak chemicals that damage your CD player’s electronic
parts.
Wipe the CD player with a damp cloth occasionally to keep it looking
new. Do not use harsh chemicals, cleaning solvents, or strong deter-
gents to clean the CD player.
Modifying or tampering with the CD player’s internal components can cause a mal-
function and might invalidate your CD player’s warranty and void your FCC authoriza-
tion to operate it. If your CD player is not performing as it should, take it to your local
RadioShack store for assistance.

REPLACING THE DC
ADAPTER’S FUSE
CD CARE TIPS
Even though a CD is very durable, you
should handle it with care.
If the CD player stops operating, check
the fuse in the DC adapter’s cigarette-
lighter plug. If it has blown, follow these
steps to replace it with a 3-amp, 5 × 20
mm, fast-acting fuse such as Cat. No.
270-1054 (not supplied).
• Keep the CD inside the CD player or
in its protective case or sleeve when
you are not playing it.
• Handle a CD by its edges to avoid
fingerprints that can prevent the CD
player’s laser beam from accurately
reading the CD. Your local Ra-
dioShack store sells a suitable CD
cleaner kit.
Caution: Using a fuse that does not
meet these ratings can damage your CD
player or the vehicle’s electrical system.
1. Carefully unscrew the tip of the ciga-
rette-lighter plug.
• Do not write on either side of the
CD, particularly the non-label side.
(Signals are read from the non-label
side.)
• Keep the CD dry. A water drop can
act as a lens and affect the laser
beam’s focus.
2. Remove the old fuse and replace it
with the new fuse.
• Never use chemicals such as record
cleaning sprays, anti-static sprays
or fluids, benzene or thinner to clean
CDs. These chemicals will perma-
nently damage the plastic surface of
the CD.
3. Screw the cigarette-lighter plug’s tip
back onto the body.
• If a CD skips when you try to play
it, the CD might be scratched. Your
local RadioShack store sells a
Scratch ’n Fix kit (Cat. No. 42-127)
that might stop the skip. Also see
“Troubleshooting” on Page 19.
