CHOOSING A POWER SOURCE
You can power your CD player from:
• Internal battery power (using two
AA alkaline or rechargeable
nickel-cadmium batteries, not supplied)
• Standard AC power (using an
optional AC adapter, not supplied)
• Vehicle battery power (using an
optional DC adapter, not supplied)
USING BATTERIES
You can power your CD player from
two AA batteries. For the best resul ts,
we recommend alkaline batteries,
such as Radio Shack Cat. No. 23-552/
557. Or, you can use rechargeable
nickel-cadmium batteries, such as Cat.
No. 23-125, and charge them in the
CD player with the supplied battery
adapter.
2. Insert two AA batteries into the
battery compartment according to
the polarity symbols (+ and –) in
the compartment.
(illus)
Notes:
• Use only fresh batteries of the
required size and type.
• Never mix fresh and old, alka-
line and nickel-cadmium batteries, or nickel-cadmium batteries
of different capacities.
• To help you remove the batter-
ies later, place them across the
ribbon.
Installing Batteries
1. Slide off the battery compartment
cover in the direction of the arrow.

3. Replace the cover.
Notes:
• Replace the batteries when
appears on the display, the sound
distorts, or the volume weakens.
• Always dispose of old batteries
promptly and properly .
• Never leave dead, old, or weak
batteries in the CD player. They
can leak chemicals and corrode or
damage electronic circuits.

42-505 6.fm Page 5 Thursday, Au gust 12, 1999 9:25 AM
• If you do not plan to use the CD
player from battery power for a
month or more, remove and sto re
the batteries. They might leak
chemicals and corrode or damage
electronic circuits.
Charging Nickel-Cadmium
Batteries
Nickel-cadmium batteries come fully
discharged. You can charge the batteries while they are in the battery compartment using the supplied battery
adapter and an optional AC adapter
(such as Cat. No. 273-1663, not supplied), or you can use an optional external battery charger (such as Cat.
No. 23-133, not supplied).

Charging Tips
• Fully discharge the batteries occasionally by playing the CD player
until it no longer plays. Then fully
recharge the batteries. This helps
restore the batteries’ full charging
capacity.
• Avoid charging the batteries in a
hot environment (higher than
113°F). Doing so can permanently
reduce the batteries’ charging
capacity.
• Do not overcharge batteries.
Overcharging can severely reduce
the batteries’ useful life.
Important:
of using nickel-cadmium batteries. At
the end of the batteries’ useful life, they
must be recycled or disposed of pro perly. 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 curb-side collection,
drop-off boxes at retailers, recycling
collection centers, and mail-back programs.

USING AC POWER
You can power your CD player with
standard AC power using a 6-volt AC
adapter such as Cat. No. 273-1663.
Caution:

delivers at least 600 milliamps. Its
center tip is set to positive, and its plug
correctly fits the CD player’s
jack. Using a n adapter that does not
meet these specifications could seriously damage the CD player or the
adapter.
To connect to AC power, insert the AC
adapter’s barrel plug into the CD player’s

• 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 wear headphones while operating a motor vehicle or riding a bicycle.
This can create a traffic ha zard and is
illegal in s ome areas.
Even though some headphones are
designed to let you hear some outside
sounds when listening at normal volume levels, they still present a traffic
hazard.

CD PLAYER TIPS
• CDs that can be played on this
player have this mark on them:
LOGO
CARING FOR COMPACT
DISCS
Even though CDs are very durable,
treat them with care.
• Do not write on either side of a
CD, particularly the non-label
side. (Signals are read from the
non-label side.)
• Do not store CDs in high-temperature, high-humidity locations. The
CDs might warp.
• Keep the CD dry. A water drop
can act as a lens and affect the
laser beam’s focus.
• Always kee p the CD in its prot ective case or sleeve when it is not
in use.
• Always handle a CD by the edges
to avoid fingerprints or scratches
on the playing surface which can
prevent the laser beam from correctly reading the digital information or create a “skipping” sound.
• If you move the player from a very
cold room to a warmer one, moisture can condense on the pickup
lens, preventing proper disc play.
If this happens, wait 30 minutes
before resuming play.
• Do not place foreign objects in the
disc tray. This can damage the
drive mechanism.
14
• To remove fingerprints and clean
the CD surface, use a CD cleaner
kit (such as Cat. No. 42-226).
• To repair scratches on the CD surface, use a CD scratch repair kit
(such as “Scratch ’n Fix”, Cat. No.
42-127).

CARE AND MAINTENANCE
Your CD-3445 Portable Compact Disc Player is an example of superior design and
craftsmanship. The following suggestions will help you care for the 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.
Handle the CD player gently and carefully. Dropping it can damage
the circuit board and case, and can cause the player to work improperly.
Use and store the CD player only in normal temperature environments. 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.
Wipe the CD player with a damp cloth occasionally to keep it looking
CLEANER
new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the CD player.
Use only fresh batteries of the required size and type. Always remove
old or weak batteries. They can leak chemicals that destroy electronic
circuits.
Modifying or tampering with the CD player’s internal components can caus e a m alfunction and might invalidate the CD player’s w arranty and void your FCC aut horization to operate it. If your CD p layer is not performing as it should, take it to your
local Radio Shack store for assistance.
