FEATURES
Your Optimus CDG Karaoke System is
one of the most versatile karaoke sys-
tems available. It lets you be the “star”
as you sing along with your favorite re-
cordings on a CD, a CDG (a compact
disc with a graphic track), a cassette
tape, or a video tape, and hear your
voice with the music through the power-
ful built-in speaker.
Your karaoke system’s features include:
Front Loading CD/CDG Player — lets
you play regular or karaoke CDs, or spe-
cial CDGs so you can experience digital
images — the latest in karaoke fun!
Plus, the player’s 16 bit D/A converter
(digital-to-analog conversion circuitry
which accurately reproduces all sound
levels with virtually no distortion) and 8
times oversampling produce high quality
sound.
The karaoke system’s CDG capability is
the latest advancement in karaoke tech-
nology. It lets you connect the karaoke
system to a TV or monitor and read the
lyrics of your favorite tunes as they scroll
by in front of a still video graphic, such
as a picture or drawing related to the
music.
Dual-Cassette Decks — let you play
two cassette tapes in a row, dub from
one tape to another, or sing with one
tape while recording on the other.
8-Watt Per Channel Amp— lets you
singalong and listen through the
karaoke system’s 5-inch woofer and 2-
inch tweeter.
You can sing along without video graph-
ics using special karaoke audio cassette
tapes (such as the one we have includ-
ed to get you started) that let you bal-
ance the volume of the original singer’s
voice and the music tracks. Or, you can
sing along with a regular prerecorded
cassette tape or CD (not supplied).
Adjustable Echo Control — lets you
add an echo to the sound for a concert
hall effect.
Tape Speed Control — lets you adjust
the tape speed to match your voice
pitch.
You can also connect another audio
source to the karaoke system, such as a
stereo VCR, and play a karaoke video
cassette (not supplied).
Supplied Karaoke CDG and Audio
Tape—letsyousingalongwiththemusic
and adjust the volume of the prerecorded
voice and music.
Note: Additional karaoke CDs, audio
cassettes, and video cassettes are
available by special order through your
local RadioShack store.

CONNECTIONS
Caution: To avoid electrical shock, do
not connect the system to AC power un-
til all other connections are complete.
If you are connecting only one micro-
phone, plug it into MIC 1. If you are add-
ing a second microphone, plug it into
MIC 2.
CONNECTING
MICROPHONES
The system has two microphone jacks
so you can use the supplied microphone
to sing along to your favorite recordings,
and connect an additional microphone
(not supplied) for duets or lead and
background vocals.
For the best performance, the additional
microphone should be a unidirectional
600-ohm dynamic microphone with a 1/4-
inch (6.35-mm) plug and an ON/OFF
switch. Your local RadioShack store has
a wide selection of microphones.
The system has a built-in microphone
holder on the right side of the system.
To use the holder, pull it down from the
side of the system, and place the micro-
phone in the holder’s grip.
Before you connect a microphone, al-
ways turn MIC VOL 1 to MIN on MIC 1,
(and MIC VOL 2 if you are connecting an
additional microphone).
7
32-1166.fm Page 8 Wednesday, November 17, 1999 4:51 PM
Note: If your audio source does not
have AUX OUT R and L jacks, but has
only a headphone or line out jack (such
as on a portable tape or CD player), use
a shielded Y-adapter cord with phono
jacks on each end (such as Cat. No. 42-
2475). Connect the single-plug end to
the audio source’s headphone or line
out jack, and connect the other end’s
two phono plugs to the system’s AUX IN
R and L jacks.
CONNECTING OTHER
AUDIO COMPONENTS
You can connect an external audio
source or component to the karaoke
system, so you can sing along with other
audio formats or videos, or hear the
karaoke’s sound from another speaker
or a PA system. To make the connec-
tion, you need optional audio patch ca-
bles (such as Cat. No. 42-2352).
Connecting an External Audio
Component for Output
Connecting an External Audio
Source for Input
You can broadcast the karaoke sys-
tem’s sound through an external audio
component such as a PA system ampli-
fier. Connect the external audio compo-
nent’s audio input jacks to the karaoke
system’s AUX OUT R and L jacks.
You can connect another audio source,
such as a stereo VCR or another CD
player, so you can sing along with the
audio source’s sound. Connect the
source’s stereo audio output jacks to the
system’s AUX IN R and L jacks.
Connecting an External
Speaker
You can connect an external 8 to15-watt
stereo speaker with 4-8 ohm impedance
to the system for a stereo effect. Plug
the speaker’s phono plug into 4-8 OHM
SPEAKER / RIGHT CHANNEL on the sys-
tem.
8
32-1166.fm Page 9 Wednesday, November 17, 1999 4:51 PM
CONNECTING TO A TV
CONNECTING POWER
You can connect the CD/CDG karaoke
system to a TV or monitor and see the
words and images produced by a spe-
cial karaoke video cassette or CD/CDG.
Plug one end of the supplied cable into
VIDEO OUT and the other end into your
TV’s video in jack.
When you have made all other connec-
tions, plug your system’s power cord
into a standard AC outlet.
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.
Note: For TVs that do not have an au-
dio/video input jack, use a video RF
modulator (such as Cat. No. 15-1283).
Connect the RF modulator to VIDEO
OUT and to the TV’s 75-Ohm VHF input
terminal, following the instructions in the
modulator’s owner’s manual.

Note: Connecting headphones automat-
ically disconnects the speakers.
Your local Radioshack store sells a wide
selection of headphones.
TAPE SPEED — To slow down or
speed up the pace of the music as you
sing along, turn TAPE SPEED toward
LOW or HIGH. For normal tape speed,
leave it set to the middle position.
LISTENING SAFELY
To protect your hearing, follow these
guidelines when you use headphones.
ECHO — You can adjust ECHO to add
an echo effect to your voice while you
sing. Turn and hold ECHO toward LOW
or HIGH for the desired effect and re-
lease.
• Set the volume to the lowest setting
before you begin listening. After you
begin listening, adjust the volume to
a comfortable level.
• Do not listen at extremely high vol-
ume levels. Extended high-volume
listening can lead to permanent
hearing loss.
TONE CONTROL — You can use TONE
CONTROL to customize the sound you
hear through the speaker. Turn TONE
CONTROL toward LOW for a low and
deep sound or HIGH for a high and
sharp sound.
• Once you set the volume, do not
increase it. Over time, your ears
adapt to the volume level, so a vol-
ume level that does not cause dis-
comfort might still damage your
hearing.

Although a CD/CDG is very durable, you
should handle it with care. We recom-
mend the following precautions:
7. Programmed play automatically
stops at the end of the last pro-
grammed track. To stop the CD/
CDG player at any time during pro-
grammed play, press STOP. The CD/
CDG’s total number of tracks and
playing time appear.
• Keep the CD/CDG in its protective
case or sleeve when you are not
playing it.
• Keep the CD/CDG clean. Your local
RadioShack store sells a suitable
CD cleaner kit.
• Do not write on either side of the
CD/CDG, particularly the non-label
side.
Reviewing/Replacing a
Programmed Sequence
• Do not store CD/CDGs in high-tem-
perature, high-humidity locations.
They might warp.
While play is stopped, repeatedly press
MEMORY to review the programmed se-
quence.
• Keep CD/CDGs dry. A water drop
can act as a lens and affect the laser
beam’s focus.
To replace a programmed track, press
MEMORY until the position number of the
track you want to replace appears. Then
repeat Steps 3 and 4 to select and store
the new track.
• Always handle a CD/CDG by the
edges to avoid fingerprints. Finger-
prints and scratches on the CD/
CDG’s surface can prevent the laser
beam from correctly reading the dig-
ital information.
Erasing a Programmed
Sequence
• If a CD/CDG skips during play, it
might be scratched. Your local
RadioShack store sells a Scratch’n
Fix kit (Cat. No. 42-127) that might
stop the skip. Also, see “Trouble-
shooting” on Page 24.
You can do any of the following to erase
a programmed sequence:
• Press STOP and MEMORY at the
same time when the CD/CDG player
stops.
• Press OPEN/CLOSE before or after
programmed play.

Erasing a Cassette Tape
TAPE CARE TIPS
If you no longer want a recording, you
can record over it or erase it.
Preventing Accidental Erasure
Most cassette tapes have two erase-
protection tabs — one for each side. To
protect a recording from accidentally be-
ing recorded over or erased, use a
screwdriver to remove one or both of the
cassette tape’s erase-protection tabs.
To erase a previously recorded section
of a tape, simply record over it.
To erase the entire cassette tape, record
silence by setting FUNCTION SELECTOR
to TAPE and recording with no tape in
TAPE 2.
You can quickly erase both sides of a
cassette tape using a bulk tape eraser
(such as Cat. No. 44-232), available at
your local RadioShack store.
If you want to record on a tape side after
you have removed the erase-protection
tab, place a piece of strong plastic tape
over that side’s erase-protection hole.
Cleaning the Tape-Handling
Parts
Dirt, dust or particles of the tape's coat-
ing can accumulate on the tape heads
and other parts that the tape touches.
This can greatly reduce the performance
of the cassette player. After every 20
hours of tape player operation, use a
cassette deck cleaning kit (Cat. No. 44-
1202) or follow these steps to clean the
tape-handling parts.
Cut off excess plastic tape
Notes:
1. Disconnect the AC power cord.
• Be sure you cover only the hole that
was originally covered by the erase-
protection tab.
2. Open the cassette compartment
doors on TAPE 1 and TAPE 2.
3. Press PLAY

4. Use a cotton swab dipped in dena-
tured 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 com-
partment doors. Then reconnect AC
power.
Your local RadioShack store sells a full
line of cassette deck cleaning supplies.
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 re-
wind 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 ob-
jects near the cassette.

RECORDING A CASSETTE TAPE
You can become a recording star! The
RECORDING YOUR VOICE
WITH MUSIC
system lets you record your voice on a
blank or reusable tape as you sing along
with a special karaoke cassette tape,
video tape, CD/CDG or other audio
source. You can also record from an ex-
ternal audio source, or dub from one
cassette tape to another.
Follow these steps to record your voice
along with music from a tape in TAPE 2,
a CD/CDG, or an audio source connect-
ed to the system’s AUX IN jacks.
1. Load a blank tape, or one that you
want to record over, into TAPE 1,
with the side you want to record on
facing out, and the full reel to the
left.
Recording Tips:
• Tape quality greatly affects the qual-
ity of the recording. We recommend
RadioShack Supertape Extended
Range or Low-Noise Type 1 tape.
We do not recommend long-play
cassette tapes, such as C-120s,
because they are thin and can easily
tangle in the cassette mechanism.
For low-noise, wide-range record-
ings, use normal-bias tape.
2. Follow Steps 1–11 in “Singing with a
CD/CDG or a Cassette Tape” on
Page 10 or Steps 1–6 in “With
Another Audio Source” on Page 11.
3. Press RECORD

CARE AND MAINTENANCE
Your Optimus CDG Karaoke System is an example of superior design and crafts-
manship. The following suggestions will help you care for your karaoke system so
you can enjoy it for years.
Keep the karaoke system dry. If it gets wet, wipe it dry immediately.
Liquids might contain minerals that can corrode the electronic circuits.
Use and store the karaoke system only in normal temperature environ-
ments. Temperature extremes can shorten the life of electronic devic-
es and distort or melt plastic parts.
Keep the karaoke system away from dust and dirt, which can cause
premature wear of parts.
Handle the karaoke system gently and carefully. Dropping it can dam-
age circuit boards and cases and can cause the karaoke system to
work improperly.
Wipe the karaoke system with a damp cloth occasionally to keep it
looking new. Do not use harsh chemicals, cleaning solvents, or strong
detergents to clean the karaoke system.
Modifying or tampering with the karaoke system’s internal components can cause
a malfunction and might invalidate its warranty. If your karaoke system is not per-
forming as it should, take it to your local RadioShack store for assistance.
