The following feature has been added to the ADCOM GCD 200/300 compact
disc player subsequent to the printing of the owner's manual.
ADCOM'S Sound Window Frequency Contour Selector
Our research indicated that the sound quality of many vocal and instrumental
CDs could be greatly Improved by introducing corrective frequency contouring
to compensate for the unnatural sonic energy balance in many CDs.
A three-position switch provides a choice of playback response curves which
can be used to improve the spectral balance of those CDs that need it.
As a result, such CDs can emulate the muslcallty of the finest analog
recordings while maintaining the low noise and dynamic range advantages
of digital technology.
The three-position selector is located on the rear panel of your compact
disc player.
Mid Position
In the mid position the Sound Window Frequency Contour Selector is
not in the audio circuit.
Upper Position
In the up position, the Sound Window Frequency Contour selector
attenuates the frequencies immediately above the range of the human
voice. This position can be used with any recordings that, due to close
microphone techniques, have a hardness or edge.
Lower Position
In the lower position, the Sound Window Frequency Contour selector
attenuates the iErequencles Just above the upper end of most musical
instruments. This position will help to relieve the harshness and glare
found in many instrumental recordings.

until it locks into place with a "click".
If the batteries are used incorrectly, there is a
danger of the internal fluid leaking or the bat
teries bursting.
Do not use new and old batteries together.
Do not use different kinds of batteries together.
Batteries consist of rechargeable and nonrechargeable types. Verify the type of battery by reading the
caution label on the battery.
If you are not going to use the remote control unit for
a long period, remove the batteries.
Do not heat, disassemble, or short circuit dry bat
teries, or throw them into a fire.
MAINTENANCE
■ Treat disc surfaces carefully
Handle the discs so that fingerprints and dust do not
adhere to the surfaces of the discs. To clean-off, use a
soft cloth. Do not use a rough cloth since this will mark
the disc.
■ Clean cabinet and panels when dirty
Clean off dirt on the surfaces with a dry cloth. Never
use thinners, benzene or alcohol since these will
damage the surface finish.

PRECAUTIONS FOR USE
• Discs which can be played on this _n compact
player have the following mark on
them
digital AUOtO
• During playback, if the player is subjected to a sud
den shock or jolt, some noise may be produced.
This is not a malfunction.
• If the player is operated while you are receiving an
FM/AM radio broadcast, you may hear noise on the
radio broadcast. In this case, turn the CD player's
power switch off.
• If other audio components or their connecting cords
are installed near this player, you may hear a hum
ming sound. In this event, try changing the location
of the other components or their wiring.
• Whenever moving the player, be sure to first remove
the disc from it. if the player is moved with a disc
loaded, the disc may be damaged.
• The gcd-200/gcd-300 has a wide dynamic range. As
a result, if you turn your amplifier's volume up too
high during soft (low volume) parts of a program,
your speakers may be damaged when the dynamic
range of a sudden loud passage is produced.
Do not move the player suddenly from a very cold
room into a warm room. When a chilled player is
moved suddenly to a warm location, moisture con
densation may form on the pickup lens, preventing
proper operation. In this case, wait 30 minutes
before resuming play.
Do not place foreign objects in the disc drawer and
attempt to operate the drawer control (Open/Close)
function. It may cause damage to the mechanism.
Do not store discs in high-temperature, highhumidity locations. The discs may develop warps
and become unplayable. Also, discs with moisture
on them may be unplayable. Wipe any moisture off
with a soft, dry cloth, and be sure discs are fully dry
before using.
If the unit is installed in a confined location, heat
dissipation will be poor and malfunctions may
occur. Also, do not install the unit on top of
amplifiers or other components liable to become hot.
