Installation
Environment
Never place this product in an environment which
could alter its performance or reduce its service life.
Such environments usually include high levels of heat,
dust, moisture, and vibration.
ImportantSafetyInstructions
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water.
6. Clean only with dry cloth.
7. Do not block any ventilation openings. nstall in accor-
dance with the manufacturer’s instructions.
8. Do not install near any heat sources such as radia-
tors, heat registers, stoves, or other apparatus (in-
cluding amplifiers) that produce heat.
9. Do not defeat the safety purpose of the polarized or
grounding-type plug. A polarized plug has two
blades with one wider than the other. A grounding
type plug has two blades and a third grounding
prong. The wide blade or the third prong are pro-
vided for your safety. f the provided plug does not
fit into your outlet, consult an electrician for replace-
ment of the obsolete outlet.
10. Protect the power cord from being walked on or
pinched particularly at plugs, convenience recep-
tacles, and the point where they exit from the ap-
paratus.
11. Only use attachments/accessories specified by
the manufacturer.
12. Use only with the cart, stand, tripod,
bracket, or table specified by the
manufacturer, or sold with the ap-
paratus. When a cart is used, use
caution when moving the cart/ap-

paratus combination to avoid injury from tip-over.
13. Unplug this apparatus during lightning storms or
when unused for long periods of time.
14. Refer all servicing to qualified service personnel.
Servicing is required when the apparatus has been
damaged in any way, such as power-supply cord or
plug is damaged, liquid has been spilled or objects
have fallen into the apparatus, the apparatus has
been exposed to rain or moisture, does not operate
normally, or has been dropped.
- AVO D EXCESS VE HEAT, HUM D TY, DUST AND V -
BRAT ON
Keep the unit away from locations where it is likely to
be exposed to high temperatures or humidity-such as
near radiators, stoves, etc. Also avoid locations which
are subject to excessive dust accumulation, or to vi-
bration that could cause mechanical damage.
- AVO D PHYS CAL SHOCKS
Strong physical shocks to the unit may cause damage.
Handle the unit with care.
- DO NOT OPEN THE CASE OR ATTEMPT REPA RS
OR MOD F CAT ONS YOURSELF
This product contains no user-serviceable parts. Refer
all maintenance to qualified nter-M service personnel.
Opening the case and/or tampering with internal cir-
cuitry voids the warranty.
- ALWAYS POWER OFF BEFORE MAK NG CONNECT ONS
Always turn the AC mains OFF before connecting or
disconnecting cables. This is important to prevent dam-
age to the unit itself as well as other connected equip-
ment.
- HANDLE CABLES CAREFULLY
Always plug and unplug cables (including the AC
mains power cord) by gripping the connector, not the
cord.
- CLEAN W TH A SOFT DRY CLOTH
Never use solvents such as benzine or paint thinner to
clean the unit. Wipe clean with a soft, dry cloth.

AdditionalExplanation■■■
MP3 (MPEG AUDIO LAYE -3)
MP3 is one of music file formats that can contain music with
stereo sound quality similar to audio CD using a type of
MPEG which is compressive standards for audio and video.
About 3~5MB is sufficient if recording music for 3min~5min
as the compression ratio is average 1Mb per minute. n ad-
dition, 130 music or more can be contained in a CD for
songs or folk song if making music files with MP3 differently
from audio CD and MP3 has advantage in play time of 10
hours. MP3 has also advantage of compacting music into
about 1/12 size while maintaining sound quality of the CD
level as it can remove frequency range impossible for human
to identify. For example, capacity of 50MB or so can be
achieved if extracting music of a CD while maintaining sound
quality of CD as it is but its size can be largely reduced to
4~5MB if compressing and converting it to a MP3.
■■■
WMA (WINDOWS MEDIA AUDIO)
WMA is Microsoft’s multimedia compression method and is
technology to compress only music data from 'Window
Media Technologies'. t provides sound quality equivalent to
128Kbps format of MP3 with 64Kbps format lower than MP3.
n other word, the file size of 1.2 MP3 provides same sound
quality as MP3.
■■■
DIGITAL OUTPUT AND SPECIFICATIONS
Sound signal of a CD is recorded via digital-conversion and
digital sound signal is converted to analog signal by digital-
analog converter (DAC) within the usual player for output.
Conversely, electrical digital signals are substituted with op-
tical signal by coaxial cables, semiconductor or light emitting
diode (LED), etc and can be connected with other devices
with optical fiber cables. The device of the party which re-
ceived optical signals converts optical signals to electrical
signals for various treatments. Direct transmission of digital
data has advantage that there is less data error as it is not
affected by electrical noise than electrical signals.

Digital interface used in this product, which has format of
S/PD F (Sony/Philips/Digital/ nterface), complies with stan-
dard specifications called EC958.
MethodtotreatCompactDisc(CD)
This device is a player only for a CD.
Please use a CD with following mark:
■■■
Make the character surface where
music name, etc is described on if mount-
ing a CD on the disc tray of the DC player.
■■■
Open a case with holding the right end-
ing part of a case with the left hand and hold the both sides
with the right hand from below.
■■■
Take off the CD with lightly holding both sides with the right
hand while pressing the center of the case with right thumb.
■■■
Lightly wipe out the CD with a soft cloth if fingerprint or dirt is
stained on the signal recording surface. There is no sound slot
like general record in the CD. Wiping out dirt or fingerprint
stained with a smooth cloth if necessary is sufficient. There is
no obstacle to sound quality even if some dirt or fingerprint re-
mains.
■■■
Record spray, charge preventing agent, benzene and thinner,
etc should not be used. The surface of a CD may be damaged
by these chemical drugs as it is a plastic product.
■■■
Please keep the disc whose play is completed in a case. f the
disc is bent or damaged, sound may be broken or become im-
possible to play with the disc.
■■■
Avoid of leaving the disc at a place where direct light is shone
or which is disclosed to high temperature or a great of humidity.
Leaving it for a place where temperature is high may cause
deformation, etc.
■■■
Do not paste papers, etc to the character surface or write let-
ters on it.
