Batteries
If you connect the supplied DC adapt er (see “Using Vehicle B attery Power”
on Page 8) or an AC adapter (see
“Using AC Power” on Page 8) 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 8 to recharge t he b at ter ie s
in the CD player. Other adapters
could damage your CD player or
the 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

Important: Your CD player is capable
of using nickel-cadmium batteries. At
the end of the batteries’ useful life,
they must be recycled or dispos ed 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.

Listening Safely
To protect your hearing, follow these
guidelines when you use earphones
or headphones.
• Set the volume to the l owest 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 highvolume 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 wear earphones or headphones while operating a motor vehicle or riding a bicycle. This can create
a traffic hazard and co uld be illegal in
some areas.
10
Even though some earphones and
headphones let you hear some outside sounds when listening at normal
volume levels, they still can present a
traffic hazard .

DIGITAL ANTI-SHOCK
SYSTEM (DAS
Your CD player contains special circuits to overcome sound skipping
problems caused by shock or vibration. This means you can carry the CD
player anywhere you go or use it in
your vehicle. When you turn on the
anti-shock system, the CD player continuously saves 3 seconds (42-5075)
or 10 seconds (42-5076) of music in
memory. During a shock or vibration
that would normally make a track skip

CARE AND MAINTENANCE
Your Optimus CD-3680/CD-369 0 Portable Compact Disc Player wi th Digital AntiShock is an example of superior design and craftsman ship. 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 e nvironments. Temperature extrem es can shorten t he life of electronic devices, damage batteries, and distort or melt plastic parts.
Keep the CD player away from dust 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 th e CD player to work improperly.
Use only fresh batteries of the required size and 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 detergents to clean the CD player.
Modifying or tampering with the CD player’s internal components can caus e a m alfunction and might invalidate your CD player’s warranty and void your FCC authorization to operate it. If your CD p layer is not performing as it should, take it to your
local RadioShack store for assistance.

REPLACING THE DC
ADAPTER’S FUSE
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 rep lace it with a
3-amp, 5 × 20 mm, fast-acting fuse
such as Cat. No. 270-1054 (no t supplied).

tip back onto the body.
CD CARE TIPS
Even though a CD is very durable, you
should handle it with care.
• 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 RadioShack store sells a
suitable CD cleaner kit.
• Do not write on either s ide 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.
• 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.
