Hold — prevents accidentally chang-
ing the CD player’s control settings
and conserves battery life by locking
most controls when you turn off the
CD player.
The CD player’s advanced technology
makes it simple to operate. But, be
sure you read this Owner’s Manual
completely so you can take advantage
of all its advanced features.
Three Power Sources — let you
power your CD player from two stan-
dard or rechargeable nickel-cadmium
AA batteries, standard AC power (with
an optional AC adapter), or your vehi-
cle’s battery (with an optional DC
adapter).
We recommend you record the CD
player’s serial number here. The num-
ber is in the battery compartment.

POWER SOURCES
You can power your CD player from:
• Two AA batteries
Cautions:
• Use only fresh batteries of the re-
quired size and recommended
type.
• Standard AC power, using an AC
adapter
• Do not mix old and new batteries,
different types of batteries (stan-
dard, alkaline, or rechargeable),
or rechargeable batteries of differ-
ent capacities.
• A vehicle’s battery power, using a
DC adapter
USING BATTERIES
All types of nickel-cadmium batteries
come fully discharged. Be sure to fully
charge the batteries before you use
them the first time.
You can power your CD player from
battery power using:
• Two AA alkaline batteries (such
as RadioShack Cat. No. 23-552)
Charging Tips
• Two special AA rechargeable
nickel-cadmium batteries (RSU
No. 11672508, available through
your local RadioShack store).
• It takes about 14 hours to charge
fully discharged nickel-cadmium
batteries in the CD player while it
is not being used to play CDs.
You can charge these batteries
while they are in the battery com-
partment using an AC or DC
adapter. (See “Using AC Power”
on Page 7 or “Using Vehicle Bat-
tery Power” on Page 8.)
• When the nickel-cadmium batter-
ies fully charge, unplug the
adapter from the AC outlet or cig-
arette-lighter socket, then discon-
nect the adapter from the CD
player.
• Two standard AA rechargeable
nickel-cadmium batteries (such
as Cat. No. 23-125).
• You can play a CD while recharg-
ing the special nickel-cadmium
batteries; however, this will cause
the batteries to recharge more
slowly.
Your CD player does not recharge
standard AA rechargeable batter-
ies inside its battery compartment,
but you can charge them with an
external battery charger (Cat. No.
23-133).
• Always keep the charging termi-
nals on the rechargeable batteries
clean. Use a cotton swab dipped
in alcohol to clean the terminals.
• Under normal usage conditions,
nickel-cadmium batteries can be
recharged about 500 times.

42-5073.fm Page 6 Thursday, August 12, 1999 11:08 AM
• Fully discharge the batteries occa-
sionally by playing the CD player
until it no longer plays. Then fully
recharge the batteries. This helps
restore the batteries’ full charging
capacity.
Installing Batteries
• Avoid charging the batteries in a
hot environment (above 113°F) as
this can permanently reduce the
batteries’ charging capacity.
1. Press down on the battery com-
partment cover and slide it away
from the CD player, then lift the
cover.
Caution: Do not overcharge the bat-
teries. Overcharging can significantly
reduce the batteries’ useful life.
2. Place two AA batteries in the com-
partment as indicated by the po-
larity symbols (+ and –) marked
inside.
Important: This CD player is capable
of using rechargeable nickel-cadmium
batteries. At the end of the batteries’
useful life, they must be recycled or
disposed of properly. Contact your lo-
cal, county, or state hazardous waste
management authorities for informa-
tion on recycling or disposal programs
in your area. Some options that might
be available are: municipal curb-side
collection, drop-off boxes at retailers
such as your local RadioShack store,
recycling collection centers, and mail-
back programs.
3. Close the battery compartment
cover.
Replace or recharge the batteries
when
flashes on the display, the
sound distorts, or the volume weak-
ens.
Cautions:
• Always dispose of old batteries
promptly and properly; do not burn
or bury them.
• If you do not plan to use the CD
player for a month or more, re-
move and store the batteries.
• Never leave dead, old, or weak
batteries in the CD player. Batter-
ies can leak chemicals that cor-
rode or damage electronic
circuits.

Follow these steps to use an AC
adapter.
USING AC POWER
You can power the CD player from a
standard AC outlet using an AC
adapter, such as Cat. No. 273-1664.
Cautions:
• You must use an AC adapter that
supplies 6 volts, and delivers at
least 400 milliamps (CD-3620) or
500 milliamps (CD-3640). Its cen-
ter tip must be set to positive, and
its barrel plug must correctly fit the

these specifications. Using an
adapter that does not meet these
specifications could damage the
CD player or the adapter.
3. Insert the adapter’s barrel plug
DC IN 6V
into the CD player’s
jack.
4. Plug the other end of the adapter
into a standard AC outlet.
• When you finish using the AC
adapter, disconnect it from the AC
outlet first, then unplug it from the
CD player.
• Battery power disconnects when
you connect an AC adapter to the
CD player unless you are using
special
rechargeable
nickel-
cadmium batteries (see “Using
Batteries” on Page 5). If you plan
to use the CD player with AC
power for an extended period of
time (8 hours or more), remove
the special nickel-cadmium batter-
ies to prevent overcharging.

CONNECTIONS
You can listen to your CD player by
connecting optional stereo earphones
or amplified speakers to the player’s
PHONES jack, or by connecting a
home audio or car stereo system to
the player’s LINE OUT jack.
Listening Safely
To protect your hearing, follow these
guidelines when you use earphones.
• Set the volume to the lowest set-
ting before you begin listening. Af-
ter you begin listening, adjust the
volume to a comfortable level.
You can mount your CD player in your
car using a mounting bracket. Your lo-
cal RadioShack store has a complete
line of mounting kits.
• Do not listen at extremely high
volume levels. Extended high-
volume listening can lead to per-
manent hearing loss.
CONNECTING
EARPHONES
• 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.
For private listening, plug a pair of ste-
reo earphones with a 1/8-inch plug (not
supplied) into the CD player’s
PHONES jack.
Traffic Safety
Do not wear earphones while operat-
ing a motor vehicle or riding a bicycle.
This can create a traffic hazard and
could be illegal in some areas.
Even though some earphones let you
hear some outside sounds when lis-
tening at normal volume levels, they
still can present a traffic hazard.

DIGITAL ANTI-SHOCK
SYSTEM (DAS2)
(CD-3640 ONLY)
Your CD-3640 contains special cir-
cuits to overcome sound skipping
problems caused by shock or vibra-
tion. 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 con-
tinuously saves the next few seconds
of music in memory. During a shock or
vibration that would normally make a
track skip or pause, the CD player
plays directly from memory.
5. When the last track finishes play-
ing, the display alternately shows
the total number of tracks and to-
tal playing time of the CD for
about 2 minutes, then the CD
player automatically turns off. To
stop play and turn off the CD
player sooner, press STOP/CLEAR
twice.
To turn on the anti-shock system, set
DAS on the left side of the CD player
to IN. If the CD player is playing a CD,
the sound briefly stops and DAS ap-
pears.
Notes:
• E-Bass turns off when the CD
player is turned off.
• If you press STOP during play,
the CD player exits INTRO,
RANDOM, and REPEAT play.

CARE AND MAINTENANCE
Your Optimus CD-3620/CD-3640 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 environ-
ments. Temperature extremes can shorten the life of electronic de-
vices, damage 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
circuit boards and cases and can cause the CD player to work im-
properly.
Use only fresh batteries of the required size and type. Old 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 authori-
zation to operate it. If your CD player is not performing as it should, take it to your
local RadioShack store for assistance.

CD CARE TIPS
FCC INFORMATION
• Do not place anything but a CD in
the disc tray. Doing so can dam-
age the drive mechanism.
This equipment complies with the lim-
its for a Class B digital device as spec-
ified in Part 15 of FCC Rules. These
limits provide reasonable protection
against radio and TV interference in a
residential area. However, your CD
player might cause TV or radio inter-
ference even when it is operating
properly. To eliminate interference,
you can try one or more of the follow-
ing corrective measures:
• During playback, a severe shock
or jolt could make the CD’s rota-
tion speed change suddenly and
produce some noise. This is not a
malfunction.
• Always handle a CD by the edges
and keep it in its protective case
or sleeve when it is not in use.
Fingerprints and scratches on the
CD’s surface can prevent the la-
ser beam from correctly reading
the digital information. To clean
the CD, use a CD cleaner kit (Cat.
No. 42-226).
• Increase the distance between the
CD player and the radio or TV.
• Use outlets on different electrical
circuits for the CD player and the
radio or TV.
• Consult your local RadioShack
store if the problem still exists.
• A scratch on the CD’s surface can
make the CD skip or stop playing.
If the CD gets scratched, use
Scratch ’n Fix (Cat. No. 42-127) to
repair the scratch.
LASER SAFETY
This unit employs a laser. Only quali-
fied service persons should remove
the cover or attempt to service this de-
vice, due to possible eye injury.
• Keep CDs dry. A water drop can
act as a lens and affect the laser
beam focus.
Warning: The use of controls or ad-
justments or the performance of pro-
cedures other than specified herein
can result in hazardous exposure to
laser light.

other than those provided by a RadioShack Authorized Service Facility; (c) consumables such as
fuses or batteries; (d) cosmetic damage; (e) transportation, shipping or insurance costs; or (f) costs
