Installing Batteries  
• Two AA alkaline batteries (not  
supplied) or one special-order  
rechargeable nickel-cadmium  
battery pack (not supplied)  
1. Slide the battery compartment  
cover in the direction of the  
arrow, then lift it open.  
• Standard AC power, using an  
AC adapter (not supplied)  
• A vehicle’s battery power, using  
a DC adapter (not supplied)  
USING BATTERIES  
2. Place two AA batteries or the  
special-order nickel cadmium  
battery pack in the compartment  
as indicated by the polarity sym-  
bols (+ and –) marked inside the  
compartment.  
You can power your CD player from  
two AA alkaline batteries, such as  
RadioShack Cat. No. 23-552, or one  
special-order rechargeable nickel-  
cadmium battery pack (Cat. No.  
RSU 11649035, available through  
your local RadioShack store). The  
CD player can recharge the special-  
order nickel-cadmium battery pack  
while it is in the CD player.

Cautions:  
Cautions:  
Use only batteries of the  
required size and type.  
• Always dispose of old batteries  
promptly and properly.  
Never mix fresh and old bat-  
teries, alkaline and nickel-  
cadmium batteries, or nickel-  
cadmium batteries of differ-  
ent capacities.  
• Never heat, disassemble, or  
throw batteries into a fire.  
• Never leave dead, old, or weak  
batteries in the CD player. Bat-  
teries can leak chemicals that  
corrode or damage electronic  
circuits.  
If you do not plan to use the  
CD player for a month or  
more, or you plan to power it  
only from an optional AC or  
DC adapter, remove and  
store the batteries.  
Charging a Nickel-  
Cadmium Battery Pack  
3. Close the battery compartment  
cover.  
The nickel-cadmium battery pack  
comes fully discharged. You can  
charge the special-order battery  
pack while it is in the battery com-  
partment using an AC adapter (such  
as Cat. No. 273-1664, not supplied)  
or DC adapter (such as Cat. No.  
273-1801, not supplied). See “Using  
AC Power” on Page 10 and “Using  
Vehicle Battery Power” on Page 11.  
When the batteries become weak,  
flashes, then the CD player  
automatically turns off. Replace al-  
kaline batteries or recharge the  
nickel-cadmium battery pack when  
this happens.

Follow these steps to recharge a  
nickel-cadmium battery pack while it  
is in the battery compartment.  
Notes:  
• It takes about 10 hours for the  
CD-3580 to charge a fully dis-  
charged nickel-cadmium battery  
pack.  
EXT DC 6V  
• You can play  
a
CD while  
recharging the battery pack;  
however, this could cause the  
battery pack to recharge more  
slowly.  
1. Set the tip polarity on the  
adapter to positive (+), and set  
the adapter’s voltage switch to  
6V.  
Charging Tips  
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.  
• Always keep the charging termi-  
nals clean. Use a cotton swab  
dipped in alcohol to clean the  
terminals.  
3. Plug the adapter’s other end  
into your vehicle’s cigarette  
lighter socket or a standard AC  
outlet.  
4. When the nickel-cadmium bat-  
tery pack fully charges, unplug  
the adapter, then disconnect the  
adapter from the CD player.  
• Under normal usage condi-  
tions, the nickel-cadmium bat-  
tery pack can be recharged  
about 500 times.

occasionally by playing the CD  
player until it no longer plays.  
Then fully recharge the battery

ity.  
recycling or disposal programs in  
your area. Some options that might  
be available are: municipal curb-side  
collection, drop-off boxes at retail-  
ers, recycling collection centers, and  
mail-back programs.  
• Avoid charging the battery pack  
in a hot environment (more than  
113°F) as this can permanently  
reduce the battery pack’s charg-  
ing capacity.  
USING AC POWER  
You can power the CD player from  
standard AC power using an AC  
adapter, such as Cat. No. 273-1664  
(not supplied).  
• Do not overcharge the battery  
pack. Overcharging can se-  
verely reduce a battery pack’s  
useful life.  
Cautions:  
You must use an AC adapter  
that supplies 6 volts and deliv-  
ers at least 550 milliamps. Its  
center tip must be set to posi-  
tive, and its plug must correctly  
fit the CD player’s EXT DC 6V  
jack. The recommended AC  
adapter meets these specifica-  
tions. Using an adapter that  
does not meet these specifica-  
tions could damage the CD  
player or the adapter.  
• 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 life, the battery pack  
must be recycled or disposed of  
properly. Contact your local, county,  
or state hazardous waste manage-  
ment authorities for information on

USING VEHICLE  
BATTERY POWER  
You can power your CD player from  
your vehicle’s battery using an op-  
tional DC adapter, such as Cat. No.  
273-1801.  
1. Attach the 4.0 mm outer diame-  
ter/1.7 mm inner diameter barrel  
plug to the adapter cord, match-  
ing the positive (+) on the plug  
with TIP on the cord.  
Cautions:  
• You must use a DC adapter that  
supplies 6 volts and delivers at  
least 550 milliamps. Its center  
tip must be set to positive, and  
its plug must correctly fit the CD  
player’s EXT DC 6V jack. The  
recommended adapter meets  
these specifications. Using an  
adapter that does not meet  
these specifications can dam-  
age the CD player or the  
2. Set the adapter’s voltage switch  
to 6V.  
3. Insert the adapter’s barrel plug  
into the CD player’s EXT DC 6V  
jack.

to 6V.  
3. Insert the adapter’s barrel plug  
into the CD player’s EXT DC 6V  
jack.  
• 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 dam-  
age, avoid leaving your CD

Traffic Safety  
Do not wear earphones while oper-  
ating a motor vehicle or riding a bicy-  
cle. This can create a traffic hazard  
and can 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  
CARING FOR THE CD-3580  
Your Optimus CD-3580 Portable Compact Disc Player is an example of supe-  
rior 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 can contain minerals that corrode the electronic cir-  
cuits.  
Handle the CD player gently and carefully. Dropping it can  
damage the circuit board and case, and can cause the player  
to work improperly.  
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  
CLEANER  
looking new. Do not use harsh chemicals, cleaning solvents,  
or strong detergents to clean the CD player.  
Use and store the CD player only in normal temperature envi-  
ronments. Temperature extremes can shorten the life of elec-  
tronic devices, damage batteries, and distort or melt plastic  
parts.

Use only fresh batteries of the required size and type. Always  
remove old or weak batteries. Batteries can leak chemicals  
that destroy electronic circuits.  
Modifying or tampering with the CD player’s internal components can cause a  
malfunction and might invalidate the CD player’s warranty and void your FCC  
authorization to operate it. If your CD player is not performing as it should,  
take it to your local RadioShack store for assistance.

• A scratch on the CD’s surface  
can make the CD skip or stop  
playing. If the CD gets  
scratched, use Scratch ’n Fix  
(RadioShack Cat. No. 42-127)  
to repair the scratch.  
CD CARE TIPS  
• If you move the player from a  
very cold room to a warmer one,  
moisture can condense on the  
pickup lens, preventing proper  
CD play. If this happens, wait 30  
minutes before resuming play.  
• Keep CDs dry. A water drop can  
act as a lens and affect the laser  
beam focus.  
• Do not place anything but a CD  
in the disc tray. This can dam-  
age the drive mechanism.  
LASER SAFETY  
• During play, a severe shock or  
jolt could make the CD’s rota-  
tion speed change suddenly  
and produce some noise. This  
is not a malfunction.  
This unit employs a laser. Only qual-  
ified service persons should remove  
the cover or attempt to service this  
device, due to possible eye injury.  
• Always handle a CD by the

information. To clean the CD,
