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.
Decibel
Level Example
30 Quiet library, soft whispers
40 Living room, refrigerator, bedroom away from traffic
50 Light traffic, normal conversation, quiet office
60 Air conditioner at 20 feet, sewing machine
70 Vacuum cleaner, hair dryer, noisy restaurant
80 Average city traffic, garbage disposals, alarm clock at two feet
THE FOLLOWING NOISES CAN BE DANGEROUS UNDER CONSTANT
EXPOSURE:
90 Subway, motorcycle, truck traffic, lawn mower
100 Garbage truck, chain saw, pneumatic drill
120 Rock band concert in front of speakers, thunderclap
140 Gunshot blast, jet engine
180 Rocket launching pad

CD OPERATION (CONTINUED)
If the CD player is subject to vibration
during playback, the bars will
disappear one by one. During the
vibration, the music should continue to
play the signals stored in the memory
until the CD player can read the music
data properly from the disc. At this
time, the indicator will probably show
fewer bars indicating the music signals
stored in memory are low.
5
If all the bars disappear and the CD
player is subject to immediate vibration,
the unit may skip.
6
If no more vibration occurs, the
music signals are once again stored
into the memory and the indicator
returns to full. When the memory is
full, the top bar will blink and the
disc rotation speed will drop to save
power consumption.

CARE AND MAINTENANCE
Caring for Compact Discs
• Treat the compact disc carefully. Handle the
compact disc only by its edges. Never allow your
fingers 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 compact disc skips or gets stuck on a section of the 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.
• This unit is designed to play only compact discs bearing the
identification logo as shown here. Other compact 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 fire or shock hazard, disconnect your unit from the AC power
source when cleaning.
•The finish 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.
