Precautions - Yamaha CC-90 Owner's Manual

PRECAUTIONS: READ THIS BEFORE OPERATING YOUR UNIT
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 unit 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 unit 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 cabinet assure proper ventilation of the unit.
If these openings are obstructed, the temperature inside the
cabinet will rise rapidly and eventually damage the circuits.
Therefore, avoid placing objects against these openings and do
not install the unit where the flow of air through the ventilation
openings could be impeded.
Always set the VOLUME control to "0" before starting the audio
source play: increase the volume gradually to an appropriate
level after the play has been started.
When not planning to use this unit 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 an appliance is not defeated.
Do not use force on switches, controls or connection wires. When
moving the unit, first disconnect the power plug and the wires
connected to other equipment. Never pull the wire itself.
Do not attempt to clean the unit 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 the unit 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 cassette deck's record/playback head assembly in this
unit. 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 cassette deck's record/playback heads used in this
unit 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 unit. Using this product with a higher voltage than that which
is specified is dangerous and may result in a fire or other type of
accident causing damage. YAMAHA will not be held responsible
for any damage resulting from use of this unit with a voltage other
than that which is specified.
The sound level at a given volume setting depends on a
combination of speaker efficiency, location and many other
factors. Care should be taken to avoid exposure to sudden high
levels of sound, which may occur when turning on the unit 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.
