Note:
not the batteries you install are rechargables, and turns on t he chargi ng c ircuit
or disconnects the batteries accordingly.
USING BATTERIES
You can power your CD pla yer from t wo
AA alkaline batteries (such as RadioShack Cat. No. 23-552) or two rechargeable AA nickel-cadmium batteries (such as Cat. No. 23-125).
Cautions
• Always use fresh, or freshly
:

size and recommended type.
Follow these steps to install the batteries.
1. Press down on the b attery compartment cover and slide it in the direction of the arrow on the cover, then
lift the cover.
Caution:
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.
Note
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).
The battery compartment

When flashes on the display, the
sound distorts, or the volume weakens,
replace or recharge the batteries.
Page 7
42-508 0.fm Page 7 Thursday, August 12, 1999 1:25 PM
Cautions:
• If you will not be using the CD player
with battery power for more than a
month, or if y ou pl an t o use only AC
or DC power, remove the batteries.
• Dispose of old batteries promptly
and properly.
Recharging Nickel-Cadmium
Batteries
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 compartment.
Cautions:
• Use only the supplied DC adapter or
an AC adapter that meets the specifications in “Using AC Power” on
Page 9 to recharge the batteries in
the CD player. Other adapters could
damage your CD player or th e batteries.
• Do not use the CD player or open
the CD compartment cover while
you are charging nickel-cadmium
batteries.
Follow these steps to charge nickelcadmium batteries in the CD player.
1. Connect an AC adapter or the supplied DC adapter to your CD player

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 properly. Contact your local, county, or state
hazardous waste management authorities for information on recycling or disposal programs in your area. Some
options that might be available are: municipal curbside collection, drop-off boxes at retailers such as your local
RadioShack store, recycling collection
centers, and mail-back programs.

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 milli amp s. Its cen ter tip mu st be
set to positive, and its plug must correctly fit the CD player’s
jack. The recommended adapter
meets these specifications. Using
an adapter that does not meet these
specifications could damage the CD
player or the adapter.
• When you finish using the AC
adapter, unplug it from the AC outlet
first, then disconnect it from the CD
player.
DC IN 6V
Follow these steps to connect the CD
player to AC power.
1. Insert the AC adapter’s 4.0 mm
outer diameter/1.7 mm inne r diameter barrel plug into the adapter’s
cord, setting TIP to + (positive).
2. Set the AC adapter ’s voltage s witch

Listening Safely
To protect your hearing, follow these
guidelines when you use earphones or
headphones.
• Set the volu me to the lo west setting
before you begin li stening. A fter you
begin listening, adjust the volume to
a comfortable level.
• Do not li sten 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
Your local RadioShack carries a wide
variety of earphones and headphones to
use with your CD player.
10
Do not wear earphones or headphones
while operating a motor vehicle or riding
a bicycle. This can c reate a traffic hazard and could be illegal in some areas.
Even though some earphones and
headphones let you hear some outside
sounds when listening at norm al volume
levels, they still can present a traffic hazard.

CARE AND MAINTENANCE
Your Optimus CD-3790 Portable Compact Disc Player is an example of superior design and craftsmanship. The following suggestions will help you care for your CD player 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, damage batteries, and distort or melt plastic parts.
Keep the CD player away from dus t and dirt, which can cause premature wear of parts.
Handle the CD player gently and carefully. Dropping it can damage circuit boards and cases and can cause the CD player to work improperly.
Use only fresh batteries of the required size and recommende d type.
Batteries can leak chemicals that damage your CD player’s el ectronic
parts.
Wipe the CD player with a damp cloth occasionally to keep it looking
new. Do not use h arsh chemicals, cleaning sol vents, or strong detergents to clean the CD player.
Modifying or tampering with the CD player’s internal componen ts can cause a malfunction and might invalidate your CD player’s warranty and void your FCC authorization to operate it. If your CD player i s not performi ng as it should, take it to your local
RadioShack store for assistance.

mm, fast-acting fuse such as Cat. No.
270-1054 (not supplied).

CD CARE TIPS
Even though a CD is very durable, you
should handle it with care.
• Keep the CD inside th e CD player o r
in its protective case or sleeve when
you are no t play ing i t.
• Handle a CD by its edges to avoid
fingerprints that can p revent the CD
player’s laser beam from acc urately
reading the CD. Your local RadioShack store sells a suitable CD
cleaner kit.
• Do not write on either side of the
CD, particularly the non-label side.
(Signals are read from t he non-labe l
side.)
• Keep the CD dry. A water drop can
act as a lens and affect the laser
beam’s focus.
• Never use chemicals such as record
cleaning sprays, anti-static sprays
or fluids, benzene or thinner to clean
CDs. These chemicals will permanently damage the plastic surface of
the CD.
• 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.
