Handling of compact discs
CA UTI ON
1 - Introduction
The GA-100CD has been designed for the playback
of CD-DA (standard audio) format discs. In addition
to ordinary 5-inch and 3-inch CDs, it can also play
properly recorded CD-R and CD-RW discs.
Always place CDs in the tray with their labeled sides
•
facing upward.
To remove a disc from its case, press down on the
•
center of the disc holder, then lift the disc out, hold
ing it carefully by the edges.
Avoid getting fingerprints on the signal side (the
•
non-label side). Grime and dust may cause skipping,
so keep discs clean and store them in their cases
when not being played. To clean the signal side of a
disc, wipe gently with a soft dry cloth from the cen
ter towards the outside edge.
•
Keep discs away from direct sunlight, and places of
high heat and humidity. If left in such places, warp
ing could result.
Do not affix any labels or stickers to the label side of
•
the disc. Do not write on the disc with ballpoint pens.
Do not use cracked discs.
•
Only use circular compact discs. Avoid using non-
-
-
•
circular promotional discs, etc.
The GA-100CD cannot play CD-R/RW discs that are
•
not finalized.
Several record companies have released music discs
•
that use Copy Control and other copy-protection
systems in an effort to prevent piracy. Since some
of these discs do not comply with the CD specifica
tions, the
After opening the CD player cover, if the CD is still
•
spinning, wait until it has stopped before removing it.
GA-100CD may not be able to play them.
-
-
Do not use any record spray, anti-static solutions,
•
benzene, paint thinner or other chemical agents to
clean CDs as they could damage the delicate playing
surface. This may cause CDs to become unplayable.
Discs should be returned to their cases after use to
•
avoid serious scratches that could cause the laser
pickup to “skip.”
Beware of condensation
If the unit (or a compact disc) is moved from a cold to a
warm place, or used after a sudden temperature change,
there is a danger of condensation; vapor in the air could
condense on the internal mechanism, making correct
Precautions for placement and use
Do not place the unit in the following types of places.
Placement in such locations may cause malfunction or
reduce sound quality.
•
Unstable places or places with frequent vibrations
•
Near windows or in direct sunlight
•
Near heating devices or other extremely hot places
•
Extremely cold places
•
Damp or poorly ventilated places
Placing this amp near another power amplifier or
another device with a large transformer can cause hum.
Using commercially available CD stabilizers or
printable recordable discs with this player will
damage the mechanism and cause it to malfunction.
Never use a disc that has had a stabilizer mounted to
it. The residual adhesive may cause the disc to stick
to the turntable of the GA-100CD. If it sticks to the
turntable, you will need a technician to get it out.
operation impossible. To prevent this, or if this occurs,
let the player sit for one or two hours at the new room
temperature before using.
Adjust the distance and angle between the devices if
this occurs.
Operation of the GA-100CD near a television or radio
may cause color distortion on the television screen
or noise in the radio signal. If this occurs, move the
GA-100CD farther away.
Use of mobile phones and other wireless devices near
the GA-100CD may cause the amp to produce noise
during use or when calls are made or received. If this
occurs, turn off the device or move it away from the
GA-100CD.
