FEATURES
Your Optimus Stereo Dual-Cassette
Karaoke Center lets you be the “star”
as you sing along with your favorite
recordings and hear your voice with
the music through the system’s speak-
er. You can sing along with regular
cassette tapes, or with special
karaoke cassette tapes (such as the
supplied tape) that let you balance the
volume of the recording’s voice, your
voice, and the music.
The system’s compact design and
convenient carrying handle let you
take it almost anywhere. You can also
connect another audio source (such
as a stereo VCR or a CD player) to the
system and sing along. If you connect
a stereo VCR and play a karaoke mu-
sic video cassette, the cassette shows
the lyrics on a TV and lets you adjust
the volume of the original singer’s
voice and the recording’s music.
Note: Additional karaoke cassette
tapes, as well as karaoke video cas-
settes, are available through Ra-
dioShack Unlimited. See your local
RadioShack store for ordering infor-
mation.

MAKING THE CONNECTIONS
CONNECTING POWER
Caution: To prevent damage to your
system, be sure to set AC/DC inside
the battery compartment to AC when
using AC power or to DC when using
internal batteries or DC power.
Using AC Power
You can power the system from a
standard AC outlet using the supplied
power cord.
Caution: The supplied power cord
has a polarized plug that fits into the
outlet only one way. If the plug does
not fit properly, turn it over and try
again. Do not force it.
1. Press the battery compartment
tabs in the direction of the arrows
and lift off the cover.
2. Remove the power cord from the
lower shelf in the battery compart-
ment and plug it into a standard
AC outlet.
3. Replace the cover, making sure
the cord is routed through the
cover’s slot.
Installing Batteries
You can power your system using
eight D batteries (not supplied). For
the best performance and longest life,
we recommend alkaline batteries,
such as RadioShack Cat. No. 23-550.
Cautions:
• Always use fresh batteries of the
required size and recommended
type.
• Do not mix old and new batteries,
different types of batteries (stan-
dard, alkaline, or rechargeable),
or rechargeable batteries of differ-
ent capacities.
Follow these steps to install batteries.
1. Press the battery compartment
tabs in the direction of the arrows
and lift off the cover.
32-1161.fm Page 5 Monday, August 9, 1999 2:49 PM

2. Insert the batteries in the compart-
ment on top of the attached rib-
bon, as indicated by the polarity
symbols (+ and –) marked inside.
3. Replace the cover.
If you are using the system with bat-
tery power and the sound becomes
weak or distorted, replace the batter-
ies. Pull up on the ribbon to remove
the batteries.
Cautions:
• If you do not plan to use the sys-
tem with batteries for a week or
more, or if you plan to use only an
AC or DC adapter, remove the
batteries. Batteries can leak
chemicals that can destroy elec-
tronic parts.
• Dispose of old batteries promptly
and properly. Do not burn or bury
them.
Using DC Power
You can also power the system from
your vehicle’s battery with a DC
adapter (such as Cat. No. 270-1562,
not supplied).
Cautions:
• The adapter must supply 12 volts
and at least 3 amps, its center tip
must be set to positive, and its
plug must correctly fit the DC 12 V
jack. The recommended adapter
meets these requirements. Using
an adapter that does not meet
these requirements could damage
the system or the adapter.
• To avoid electrical shock and
damage to the system and vehi-
cle, always unplug the adapter
from the cigarette-lighter socket
before unplugging it from the sys-
tem.
1. Insert the adapter’s 5.5 mm outer
diameter/2.5 mm inner diameter
barrel plug into the adapter’s cord.
2. Insert the plug into the DC 12 V
jack on the back of the system.
3. Then plug the large end of the DC
adapter cord into your vehicle’s
cigarette-lighter socket.

CONNECTING AN
EXTERNAL AUDIO
SOURCE FOR INPUT
To connect another audio source
(such as a stereo VCR or CD player)
so you can sing along with the audio
source’s sound, connect the audio
source’s stereo audio output jacks to
the system’s AUX IN R and Ljacks.
Note: If the external audio source
does not have AUX OUT jacks, but
has only a headphone output jack
(such as one you might find on a por-
table tape or CD player), use a shield-
ed Y-adapter cord, such as Cat. No.
42-2475. Connect the single-plug end
to the audio source’s headphone jack,
and connect the other end’s two
phono plugs to the system’s AUX IN R
and L jacks.
CONNECTING AN AUDIO
COMPONENT FOR
OUTPUT
To connect an audio component (such
as a PA system amplifier) so you can
hear the system’s sound through it,
plug the audio component into the
AUX OUT jacks.
CONNECTING AN
EXTERNAL SPEAKER
To connect an external stereo speaker
(with 4 ohms and 20-watt impedance),
plug the speaker into the system’s R.
CHAN OUTPUT jack.
Caution: To avoid damage to the sys-
tem, adapter, and vehicle, do not use
a DC adapter while an external speak-
er is connected to your karaoke cen-
ter.

CARE AND MAINTENANCE
To enjoy your Optimus Stereo Dual-
Cassette Karaoke Center for a long
time:
• Keep the system dry. If it gets wet,
wipe it dry immediately.
• Use and store the system only in
normal temperature environ-
ments.
• Handle the system gently and
carefully. Don't drop it.
• Keep the system away from dust
and dirt.
• Wipe the system with a damp
cloth occasionally to keep it look-
ing new.
Modifying or tampering with the sys-
tem's internal components can cause
a malfunction and invalidate its war-
ranty. If your system is not performing
as it should, take it to your local Ra-
dioShack store for assistance.
TAPE TIPS
Erasing a Cassette Tape
If you no longer want a recording, you
can record over or erase it.
To erase a previously recorded sec-
tion of a tape, simply record over it. To
erase the entire cassette tape, let the
tape record to the end.
You can quickly erase both sides of a
cassette tape using a bulk tape eraser
(such as Cat. No. 44-232).
Preventing Accidental
Erasure
Cassette tapes have two erase-
protection tabs — one for each side.
To protect a recording from being ac-
cidentally recorded over or erased,
use a screwdriver to remove one or
both of the cassette tape’s erase-
protection tabs.
If you want to record on a tape after
you have removed the erase-
protection tab, place a piece of strong
plastic tape over that side’s erase-
protection hole. Be sure you cover
only the hole originally covered by the
erase-protection tab.
Note: Removing the erase-protection
tabs does not prevent a bulk eraser
from erasing a cassette tape.
32-1161.fm Page 17 Monday, August 9, 1999 2:49 PM

18
Restoring Tape Tension and
Sound Quality
After you play a cassette tape several
times, the tape might become tightly
wound on the reels. This can cause
playback sound quality to deteriorate.
To restore the sound quality, fast-
forward the tape from the beginning to
the end of one side, then completely
rewind it. Then loosen the tape reels
by gently tapping each side of the cas-
sette’s outer shell on a flat surface.
Caution: Be careful not to damage
the cassette when tapping it. Do not
touch the exposed tape or allow any
sharp objects near the cassette.
Cleaning the Tape-Handling
Parts
Dirt, dust, or particles of the tape’s
coating can accumulate on the tape
heads and other parts that the tape
touches. This can greatly reduce the
performance of the cassette player.
Use the following cleaning procedure
after every 20 hours of tape player op-
eration.
1. Remove the batteries, and discon-
nect the AC power cord or DC
adapter.
2. Press STOP/EJECT on TAPE 1
and TAPE 2 to open the cassette
compartment doors.
3. Press PLAY on TAPE 1 and TAPE
2 to expose the tape-handling
parts.
4. Use a cotton swab dipped in
denatured alcohol or tape head
cleaning solution to clean the
record/play heads, pinch rollers,
capstans, tape guides, and erase
heads.
5. When you finish cleaning, press
STOP/EJECT on TAPE 1 and
TAPE 2 and close the cassette
compartment doors. Then recon-
nect power.
Your local RadioShack store sells a
complete line of cassette deck clean-
ing supplies.

ARE LIMITED IN DURATION TO THE DURATION OF THE WRITTEN LIMITED WARRANTIES
CONTAINED HEREIN. EXCEPT AS PROVIDED HEREIN, RadioShack SHALL HAVE NO LIABIL-

Some states do not allow the limitations on how long an implied warranty lasts or the exclusion of in-
cidental or consequential damages, so the above limitations or exclusions may not apply to you.
In the event of a product defect during the warranty period, take the product and the RadioShack

less otherwise provided by law: (a) correct the defect by product repair without charge for parts and
labor; (b) replace the product with one of the same or similar design; or (c) refund the purchase
price. All replaced parts and products, and products on which a refund is made, become the prop-
erty of RadioShack. New or reconditioned parts and products may be used in the performance of
warranty service. Repaired or replaced parts and products are warranted for the remainder of the
original warranty period. You will be charged for repair or replacement of the product made after the
expiration of the warranty period.
This warranty does not cover: (a) damage or failure caused by or attributable to acts of God, abuse,
accident, misuse, improper or abnormal usage, failure to follow instructions, improper installation or
maintenance, alteration, lightning or other incidence of excess voltage or current; (b) any repairs
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
of product removal, installation, set-up service adjustment or reinstallation.
