VIBRATION

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 vibration that could cause mechanical damage.

- AVOID PHYSICAL SHOCKS

Strong physi cal shocks to the unit may cause
damage. Handle the unit with care.

- DO NOT OPEN THE CASE OR ATTEMPT REPAIRS

OR MODIFICATIONS YOURSELF
This product contains no user-serviceable parts.
Refer all maintenance to qualified Inter-M service
personnel. Opening the case and/or tampering with
internal circuitry voids the warranty.

AdditionalExplanation

MP3 (MPEG AUDIO LAYER-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. In addition,  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'. It provides sound quality equivalent
to 128Kbps format of MP3 with 64Kbps format lower than
MP3. In 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 digital­analog converter (DAC) within the usual player for output.
Conversely, electrical digital signals are substituted with
optical 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 received 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

8

PAM-MPM4 (CD MP3 TUNER Module)

it is not affected by electrical noise than electrical signals.
Digital interface used in this product, which has format of
S/PDIF (Sony/Philips/Digital/Interface), complies with
standard specifications called IEC958.

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
mounting a CD on the disc tray of the DC
player.

■■

Open a case with holding the right ending 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
remains.

■■

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. If
the disc is bent or damaged, sound may be broken or
become impossible 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
letters on it.
