POWER SOURCES
You can power your CD player from:
• Two AA batteries
• Standard AC power, using an AC adapter
• A vehicle’s battery power, using a DC adapter
USING BATTERIES
You can power your CD player from battery power using:
Two AA alk aline batteri es

special
Two nickel-cadmium batteries
No. 11672508, available through your local RadioShack store).
You can charge these batteries while they are in th e battery com­partment using an AC or DC adapter. (See “Using AC Power” on Page 7 or “Using Vehicle Bat­tery Power” on Page 8.)
Two standard AA rechar nickel-cadmium batteries
as Cat. No. 23-125). Your CD player does not recharge
standard AA rechargeable batter­ies inside its battery compartment, but you can charge them with an external battery charger (Cat. No. 23-133).

Cautions:
• Use only fresh ba tteries of the re­quired size and recommended type.
• Do not mix old and new batteries, different types of batteries (stan­dard, alkaline, or rechargeable), or rechargeable batteries of differ­ent capacities.

Page 6
• 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 (above 113°F) as this can permanently reduce the batteries’ charging capacity.
Caution: Do not overcharge the bat­teries. Overcharging can significantly reduce the batteries’ useful life.
Important: Th is CD player is c apable of using rechargeable 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 d isposal program s 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.
Installing Batteries
1. Press down on the battery com­partment cover and slide it away from the CD player, then lift the cover.
2. Place two AA batteries in the com­partment as indicated by the po­larity symbols (+ and –) marked inside.
3. Close the battery compartment cover.
Replace or recharge the batteries when flashes on the display, the sound distorts, or the volume weak­ens.
Cautions:
• Always dispose of old batteries promptly and properly; do not burn or bury them.
• If you do no t plan to use the CD player for a month or more, re­move and store the batteries.
• Never leave dead, old, or weak batteries in the CD player. Batter­ies can leak chemicals that cor­rode or damage electronic circuits.

USING AC POWER
You can power the CD play er 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 cen­ter tip must be set to positive, and its barrel pl u g must co rre ctly fit th e CD player’s recommended adapter meets these specifications. Using an adapter that does no t meet these specifications could damage the CD player or the adapter .
• When you finish using the AC adapter, disconnect it from the AC outlet first, then unplug it from the CD player.

USING VEHICLE BATTERY POWER
You can power your CD player from your vehicle’s battery using a DC adapter, such as Cat. No. 273-1801.
Cautions:
• You must use a DC adapter that supplies 6 volts and delivers at least 500 milliam ps. Its center tip must be set to positive, and its barrel plug must correctly fit the CD player’s recommended adapter meets these specifications. Using an adapter that does no t meet these specifications can damage the CD player or the adapter.
• Disconnect the adapter from the cigarette-lighter socket when you are not using it, to prevent the ve­hicle’s battery from being drained.
• Always disconnect the adapter from the cigarette-lighter socket before you unplug it from the CD player.
• If you park your vehicle in the sun, temperatures inside can easily reach levels that could damage your CD player and your CDs. To prevent heat damage, avoid leav­ing your CD player or CDs in your vehicle.

Listening Safely
To protect your hearing, follow these guidelines when you use earphones.
• 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 whil e operat­ing 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 lis­tening at normal volume levels, they still can present a traffic hazard.

CARE AND MAINTENANCE
Your Optimus CD-3620/CD-3640 Portable Compac t 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 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 t he required size and t ype. Old bat teries 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.

CD CARE TIPS
• Do not place anything but a CD in the disc tray. Doing so can dam­age the drive mechanism.
• During playback, a severe shock or jolt could make the CD’s rota­tion speed change suddenly and produce some noise. This is not a malfunc tio n.
• Always handle a CD by the edg es 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 la­ser beam from correctly reading the digital information. To clean the CD, use a CD cleaner kit (Cat. No. 42-226).
• 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.
• Keep CDs dry. A water drop can act as a lens and affect the las er beam focus.
FCC INFORMATION
This equipment complies with the lim­its for a Class B digital device as spec­ified in Part 15 of limits provide reasonable protection against radio and TV interference in a residential area. However, your CD player might cause TV or radio inter­ference even when it is operating properly. To eliminate interference, you can try one or more of the follow­ing corrective measures:
• 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.
