CHOOSING A POWER SOURCE

You can power your CD player from:

• Two AA alkaline batteries (not supplied) or one special-order rechargeable nickel-cadmium battery pack (not supplied)

• A vehicle’s battery power, using the supplied DC adapter

• Standard AC power, using an AC adapter (not supplied)

USING BATTERIES

You can power your CD player from two AA alkaline batteries, such as RadioShack Cat. No. 23-552, or one special-order rechargeable nickelcadmium battery pack (Cat. No. RSU 11649035, available through your local RadioShack store). The CD player can recharge the specialorder nickel-cadmium battery pack while it is installed.

Installing Batteries

1. Slide the battery compartment cover in the direction of the arrow, then lift it open.

2. Place two AA batteries or the special-order nickel cadmium battery pack in the compart m ent as indicated by the polari ty symbols (+ and –) marked inside the compartment.

42-506 9.fm Page 8 Thursday, Augu st 12, 1999 10:28 AM

Cautions:

• Use only fresh batteries of the required size and type.

• Never mix fresh and old batteries, alkaline and nickelcadmium batteries, or nickelcadmium batteries of different capaciti es.

• If you do not plan to use the CD player for a month or more, or you plan to power it only from an AC or DC adapter, remove and store the batteries.

3. Close the battery compartment cover.

When the batteries become weak,

flashes, then the CD player automatically turns off. Replace alkaline batteries or recharge the nickel-cadmium battery pack when this happens.

Cautions:

• Always dispose of old batteries promptly and properly.

• Never heat, disassemble, or throw b at te ries into a fir e .

• Never leave dead, old, or weak batteries in the CD player. Batteries can leak chemicals that corrode or damage electronic circuits.

Charging a NickelCadmiu m B attery Pac k

The nickel-cadmium battery pack comes fully discharged. You can charge the special-order battery pack while it is in the battery compartment using the supplied DC adapter or an AC adapter (such as Cat. No. 273-1664, not supplied). See “Using Vehicle Battery Power” on Page 10 and “Using AC Power” on Pa ge 12.

42-506 9.fm Page 9 Thursday, Augu st 12, 1999 10:28 AM

Follow these steps to recharge the nickel-cadmium battery pack while it is in the battery compartment.

1. Set the tip polarity on the adapter to positive (+), and set the adapter’s voltage switch to 6V.

2. Insert the adapter’s 4.0 mm outer diameter/1.7 mm inner diameter barrel plug into the CD player’s

EXT DC 6V

jack.

3. Plug the adapter’s other end into your vehicle’s cigarette lighter socket or a standard AC outlet.

4. When the nickel-cadmium battery pack fully charges, unplug the adapter, then disco nnect the adapter from the CD playe r.

Notes:

• It takes about 10 hours for the CD-3590 to charge a fully discharged nickel-cadmium battery pack.

• You can play a CD while recharging the battery pack; howeve r, this will caus e the bat tery pack to recharge more slowly.

Charging Tips

• Alw ay s keep the cha r ging termi nals clean. Use a cotton swab dipped in alcohol to clean the terminals.

42-506 9.fm Page 10 Thursday, August 12, 1999 10:28 AM

• Under normal usage conditions, the nickel-cadmium battery pack can be recharged about 500 times.

• Fully discharge the battery pack occasionally by playing the CD player until it no longer plays. Then fully recharge the battery pack. This helps restore the battery pack’s full charging capacity.

• Avoid charging the battery pack in a hot environment (more than 113°F) as this can permanently reduce the battery pack’ s charging capacity.

• Do not overcharge the battery pack. Overcharging can severely reduce a bat tery pack’s useful life.

• Do not short-circuit the battery pack’s terminals (+ and –).

Important: This portable CD player is capable of using a rechargeable nickel-cadmium battery pack. At the end of its useful l ife, the battery pack

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 curb-side collection, drop-off boxes at retailers, recycling collection centers, and mail-back programs.

USING VEHICLE BATTERY POWER

You can power your CD player from your vehicle’s battery using the supplied DC adapter.

Cautions:

• 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.
