FEATURES
Your Optimus Dual-Cassette Karaoke
System lets you be the “star” as you s ing
along with your favorite recordings and
hear your voice wi th the music through
the speaker. You can sing along with
special karaoke audio cassette tapes
(such as the one we have included to
get you started) that let yo u balance t he
volume of the original singer’s voice and

You can also connect another audio
source, such as a CD player or stereo
VCR, to the karaoke system.
If you connect a stereo VCR to the
karaoke system and play a karaoke video cassette (not included), the video
cassette shows the lyrics on a TV, and
the system lets you adjust the volume of
the prerecorded original singer’s voice
and music as you sing along.

types of audio/video components, su ch
as a stereo VCR, CD player, or PA system to your karaoke system. These connections might require additional
supplies, which are available from your
local RadioShack store.
CONNECTING POWER
You can power your karaoke system using any of the following power sources.
• AC power
• Eight D ba tteries
• Vehicle battery power
Using AC Power
The supplied power cord stored inside
the battery compartment lets you pow er

outlet.
2. While pressing both tabs on the battery compartment cover in the direction of the arrow, pull the cover
down to remove it.
3. Unroll the power cord from its storage area in the battery compartment, then plug it into a standard AC
outlet.
4. Replace the battery compartment
cover.
Caution

only one way. If the plug does not fit
properly, turn it over and try again. Do
not fo r c e i t .
1. Set
: The supplied power cord has a
DC/AC
on the back of the
karaoke system to
AC
.
Installing Batteries
You can power the karaoke system with
eight D batteries (not supplied). For the
best performance, we recommend alkaline batteries, such as RadioShack Cat.
No. 23-650.
Cautions:
• Use only fresh batteries of the
required size and recommended
type.
5
32-116 2.fm Page 6 Monda y, August 9, 1999 3:01 PM
• Do not mix old and new batteries,
different types of batteries (standard, alkaline, or rechargeable), or
rechargeable batteries of different
capacities.
Follow these steps to install batteries.
1. Set
DC/AC
on the back of the
karaoke system to
DC
.
2. While pressing both tabs on the battery compartment cover in the direction of the arrow, pull the cover
down to remove it.
3. Move the power cord from its storage area in the battery compartment.
4. Install the batteries in the compartment and on top of the attached ribbon, as indicated by the polarity
symbols (+ and –) marked inside.
5. Replace the battery compartment
cover. (Keep the power cord out of
the way of normal traffic while using
battery power.)
If the karaoke system’s sound becom es
weak or distorted, replace the batteries.
Cautions
:
• Always remove old or weak b atteries. Batteries can leak chemicals
that can destroy electronic parts.
• If you do not plan to use the karaoke
system with batteries for several
days, or if you plan to use o nly the
supplied power cord or a DC
adapter, remove the batteries.
• Dispose of old batteries promptly
and properly. Do not burn or bury

AUDIO COMPONENTS
You can connect an external audio
source or component to the karaoke
system, so you can sing along with other
audio formats like CDs or videos, or
hear the karaoke’s sound from other
speakers like a PA system. To make the
connection you need optional audio
patch cables (such as Cat. No. 42-
2352).
Connecting an External Audio
Source for Input

player) by connecting its audio output
jacks to the system’s
IN L
jacks.
AUX IN R
and
AUX
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 portable tape or CD player), use a shielded Y-adapter cord such
as Cat. No. 42-2475. Connect the single-plug end to the audio source’s headphone jack, and c onnect t he o the r end’s
two phono plugs t o the system’s
AUX IN L
