Dear Customer  
Selecting fine audio equipment such as the unit you’ve just purchased is only the start of your musical  
enjoyment. Now it’s time to consider how you can maximize the fun and excitement your equipment offers.  
This manufacturer and the Electronic Industries Association’s Consumer Electronics Group want you to get  
the most out of your equipment by playing it at a safe level. One that lets the sound come through loud and  
clear without annoying blaring or distortion and, most importantly, without affecting your sensitive hearing.  
Sound can be deceiving. Over time your hearing “comfort level” adapts to higher volumes of sound. So what  
sounds “normal” can actually be loud and harmful to your hearing. Guard against this by setting your  
equipment at a safe level BEFORE your hearing adapts.  
To establish a safe level:  
• Start your volume control at a low setting.  
• Slowly increase the sound until you can hear it comfortably and clearly, and without distortion.  
Once you have established a comfortable sound level:  
• Set the dial and leave it there.  
Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all, we want  
you listening for a lifetime.  
We Want You Listening For A Lifetime  
Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since hearing damage  
from loud noise is often undetectable until it is too late, this manufacturer and the Electronic Industries  
Association’s Consumer Electronics Group recommend you avoid prolonged exposure to excessive noise.  
This list of sound levels is included for your protection.

To protect your product from a lightning storm, or when it is left  
unattended and unused for long periods of time, unplug it from the wall  
outlet and disconnect the antenna or cable system. This will prevent  
damage to the product due to lightning and power-line surges.  
14. POWER LINES  
This reminder is provided to call the CATV system installer's attention  
to Article 820-40 of the NEC that provides guidelines for proper  
grounding and, in particular, specifies that the cable ground shall be  
connected to the grounding system of the building, as close to the point  
of cable entry as practical.  
An outside antenna system should not be located in the vicinity of  
overhead power lines or other electric light or power circuits, or where it  
can fall into such power lines or circuits. When installing an outside  
antenna system, extreme care should be taken to keep from touching  
such power lines or circuits as contact with them might be fatal.

GRAPHICS  
Many newer TV sets have a set of Video and Stereo Audio jacks on the front panel for quick and  
easy connections without having to turn the TV set to gain access to the jacks on the back panel. If your TV  
set has such front panel A/V jacks, we suggest that you use those jacks to connect your portable Karaoke.  
After connecting the Video Out jack on this portable Karaoke to the Video In jack on your TV with the  
included video cable, you have the following three choices:  
1. Listen to the sound from the built-in speakers in this portable Karaoke system. In this case, no external  
audio connections are required.  
2. If your TV has stereo audio input jacks, you can connect the Audio Out jacks on the back of this unit to  
the Audio In jacks on your TV. The stereo audio connection cable is included. In this case, the lyrics from  
the CD+G disc will appear on your TV screen and the sound from the disc will be heard from your TV  
speakers.

IMPORTANT: This feature only  
works with multiplex CDs.  
NOTE: The Program and Repeat features on a CD+G CD operate the same as with standard CD.  
INFORMATION ABOUT CD+G KARAOKE DISCS:  
CD+G Karaoke discs are designed specifically for playback in special CD players that include a CD+G decoder, such as  
this unit. These discs contain the lyrics to each song and the lyrics will appear on your TV screen, line by line, as the disc  
is playing. Usually the words on the screen will change color in time with the music to help you sing along at the proper  
tempo, even if you do not know the song.  
Most CD+G Karaoke discs have all of the songs recorded twice, first with music only, and then with music and vocal  
together. For example, if you purchase a CD+G disc containing four songs, tracks one through four will have the music  
only without vocals, and tracks five through eight will have the same four songs recorded with music on the left channel  
and the vocal tracks on the right channel.  
If you wish to sing along “solo” without any other vocals, you should select tracks one through four (for example). If you  
wish to sing a “duet” or be part of a group, select tracks five through eight (for example) that contain both the music and  
vocals.  
NOTE: Make sure the BALANCE control is set to the center position so you can hear both the vocal and music tracks at  
an equal level.  
MICROPHONE FEEDBACK:  
“Feedback” is a howling or screeching sound that occurs when the microphone comes too close to the speaker(s). To  
avoid microphone feedback, keep the microphone as far away from the speakers as the microphone cable will allow. If  
you must bring the microphone close to the speakers, such as when you are changing a disc or adjusting one of the  
other controls on the front of the unit, set the microphone ON/OFF switch to the OFF position.

CARE AND MAINTENANCE  
SAFEGUARD AGAINST ACCIDENTAL ERASURE  
When a new recording is made, any program  
material previously recorded is automatically  
erased and only the new recording remains. To  
safeguard valuable recordings from being erased  
accidentally, the cassette and the deck are  
equipped with a special device.  
On the back of the cassette there is an erase  
prevention tab on each side. To prevent  
accidental erasing, break out these tabs with a  
screwdriver. If only one side of the tape is to be  
protected, break out the tab on the left side with  
the side desired facing you.  
To record on a tape in which the tab has been  
broken, place a piece of adhesive tape over that  
area.  
NOTE: When a tab is broken out, the record  
button cannot be depressed.  
CASSETTE TAPE RECOMMENDATIONS  
Standard tape lengths have 15 (C-30), 30 (C-60) and 45 (C-90) minutes of recording time on each side.  
Longer length tapes of 60 (C-120) minutes of recording time on each side are not recommended. Use only  
high quality tapes. If a problem develops, check the unit rst with another cassette to determine if the  
problem is with the cassette, and not with the unit.  
If there is any slack in the cassette, it should be removed before inserting the cassette. Place a pencil in one  
of the hubs and rotate it clockwise until all slack is taken up.

CARE AND MAINTENANCE (CONTINUED)  
Caring for Compact Discs  
• Treat the compact disc carefully. Handle the compact disc  
only by its edges. Never allow your ngers to come in contact  
with the shiny, unprinted side of the compact disc.  
• Do not attach adhesive tape, stickers, etc. to the compact  
disc label.  
• Clean the compact disc periodically with a soft, lint-free,  
dry cloth. Never use detergents or abrasive cleaners to  
clean the compact disc. If necessary, use a CD cleaning kit.  
• If a disc skips or gets stuck on a section of the compact disc, it is probably dirty or damaged (scratched).  
• When cleaning the compact disc, wipe in straight lines from the center of the compact disc to the outer  
edge of the compact disc. Never wipe in circular motions.  
Z
• This unit is designed to play only compact discs bearing the identification logo as shown here.  
Other discs may not conform to the CD standard and may not play properly.  
• Compact Discs should be stored in their cases after each use to avoid damage.  
• Do not expose compact discs to direct sunlight, high humidity, high temperatures, or dust, etc. Prolonged  
exposure or extreme temperatures can warp the compact disc.  
• Do not stick or write anything on either side of the compact disc. Sharp writing instruments, or the ink may  
damage the surface.  
Cleaning the unit  
• To prevent re or shock hazard, disconnect your unit from the AC power source when cleaning.  
• The nish on your unit may be cleaned with a dust cloth and cared for as other furniture. Use caution  
when cleaning and wiping the plastic parts.  
• Mild soap and a damp cloth may be used on the front panel.  
• Periodic cleaning of the tape heads, capstan and pinch roller is necessary to maintain good sound  
reproduction. Clean them after every 100 hours of use or less if playback has deteriorated. Use a cotton  
swab moistened with head cleaning solution or isopropyl alcohol, then wipe dry with another swab.  
NOTE: Never use metal objects on or near the tape heads. Do not allow any cleaning material to fall into the  
tape assembly.
