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)
• Standard AC power, using an
AC adapter (not supplied)
• A vehicle’s battery power, using
a DC 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 in the CD player.
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.
7
Page 8
42-506 7.fm Page 8 Thursday, Augu st 12, 1999 10:10 AM
Cautions:
• Use only 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 optional 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 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 Page11.

Follow these steps to recharge a
nickel-cadmium battery pack while it
is in the battery compartment.
EXT DC 6V
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-3580 to charge a fully discharged nickel-cadmium battery
pack.
• You can play a CD while
recharging the battery pack;
however, this could cause the
battery 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.
• Under normal usage conditions, the nickel-cadmium battery pack can be recharged
about 500 times.
9
Page 10
42-506 7.fm Page 10 Thursday, August 12, 1999 10:10 AM
• 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 battery 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 AC POWER
You can power the CD player from
standard AC power using an AC
adapter, such as Cat. No. 273-1664
(not supplied).
Cautions:
• You must use an AC 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
jack. The recommended AC
adapter meets these specifications. Using an adapter that
does not meet these specifications could damage the CD
player or the adapter.
EXT DC 6V
10
Page 11
42-506 7.fm Page 11 Thursday, August 12, 1999 10:10 AM

• 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 while operating 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 som e outside sounds when
listening at normal volume levels,
they stil l can present a traffic hazar d.

CARE AND MAINTENANCE
CARING FOR THE CD-3580
Your Optimus CD-3580 Portable Com pact 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 immedi ately.
Liquids can contain minerals that 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.
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 deterge nts to clean the CD player.
Use and store the CD player only in normal temper ature environments. Temperature extremes can shorten the life of electronic devices, damage batteries, and distort or melt plastic
parts.
27

42-506 7.fm Page 28 Thursday, August 12, 1999 10:10 AM
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.

CD CARE TIPS
• If you move the player from a
very cold r oom to a warmer one,
moisture can condense on the
pickup lens, preventing proper
CD play. If this happens, wait 30
minutes before resuming play.
• Do not place anything but a CD
in the disc tray. This can damage the drive mechanis m.
• During play, a severe shock or
jolt could make the CD’s rotation 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 laser beam
from correctly reading the digital
information. To clean the CD,
use a CD cleaner kit (RadioShack 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
(RadioShack Cat. No. 42-127)
to repair the scratch.
• Keep CDs dry. A water drop can
act as a lens and affect the laser
beam focus.
