■
To assure the finest performance, please read this manual
carefully. Keep it in a safe place for future reference.
■
Choose the installation location of this system carefully.
Avoid placing it in direct sunlight or close to a source of
heat. Also avoid locations subject to vibration and
excessive dust, heat, cold or moisture. Keep it away from
sources of hum such as transformers and electric motors.
■
Do not operate this system upside-down. It may overheat,
possibly causing damage.
■
Never open the cabinet. If something drops into the set,
contact your dealer.
■
The openings on the main unit cover assure proper
ventilation of the main unit. If these openings are
obstructed, the temperature inside the unit will rise rapidly.
Therefore, avoid placing objects against these openings,
and install the main unit in a well-ventilated area to prevent
fire and damage.
■
Always set the VOLUME control to minimum before
starting an audio source play: increase the volume
gradually to an appropriate level after play has started.
■
When not planning to use this system for long periods of
time (ie., vacation, etc.), disconnect the AC power plug
from the wall outlet.
■
Grounding or polarization – Precautions should be taken so
that the grounding or polarization of this system is not
defeated.
■
Do not use force on switches, controls or connection wires.
When moving the main unit, first disconnect the power plug
and the wires connected to other equipment. Never pull the
wire itself.
■
If an external appliance (TV, radio, etc.) interferes with this
system operation, move the main unit away from such an
appliance.
■
Do not attempt to clean this system with chemical solvents;
this might damage the finish. Use a clean, dry cloth.
■
Be sure to read the “Troubleshooting” section regarding
common operating errors before concluding that this
system is faulty.
■
To prevent lightning damage, disconnect the AC power
plug and the antenna cable when there is an electrical
storm.
■
Do not plug the AC power plug to the wall socket before
you finish all connections.
■
Never allow metallic items (e.g. screwdrivers, tools, etc.) to
come near the tape deck’s record/playback head assembly.
Doing so may not only scratch or damage the head’s
mirror-smooth finish, it may change the magnetic
characteristics of the heads, causing a deterioration in
reproduction performance quality.
■
Although the tape deck’s record/playback heads are high
quality heads with outstanding reproduction characteristics,
they can become dirty through the use of old tapes or from
dust accumulation over time. This can have a serious effect
on reproduction quality. Clean the heads regularly with one
of the commonly available head cleaners or with cleaning
solutions.
■
The voltage to be used must be the same as that specified
on this system. Using this system with a higher voltage
than specified is dangerous and may result in a fire or other
types of accidents causing damage. YAMAHA will not be
held responsible for any damage resulting from use of this
system with a voltage other than specified.
■
The sound level at a given volume setting depends on
speaker location and other factors. Care should be taken to
avoid exposure to sudden high levels of sound, which may
occur when turning on this system with the volume control
setting at high, and to continuous high levels of sound.
■
Sudden temperature changes and storage or operation in
an extremely humid environment may cause condensation
inside the cabinet. Condensation can cause this system to
malfunction.
To eliminate condensation:
•
CD pickup/MD pickup
Leave the power on with no disc loaded until normal
play becomes possible (about 1 hour).
•
Tape head
Leave the power on with no tape loaded until normal
playback becomes possible (about 1 hour).
Note
If condensation forms on the tape head, dirt or dust
may accumulate during use.
•
Remote control
Wipe off condensation on the transmission window with
a soft cloth before operating this system.
■
To prevent a malfunction of this system:
•
Do not use any non standard shaped compact disc
(heart etc.) available on the market, because it may
damage this system.
•
Do not use a compact disc with tape, seals, or paste on
it, because damage to this system may result.
Precautions: Read this before operating your system
This system is not disconnected from the AC power
source as long as it is connected to the wall outlet, even if
this system itself is turned off. This state is called the
standby mode.
In this state, this system is designed to consume a certain
level of power.
