PRECAUTIONS
PLEASE READ CAREFULLY BEFORE PROCEEDING
* Please keep this manual in a safe place for future reference.
WARNING
Always follow the basic precautions listed below to avoid the possibility of serious injury or even death from
electrical shock, short-circuiting, damages, fire or other hazards. These precautions include, but are not limited
to, the following:
• Only use the voltage specified as correct for the device. The required
voltage is printed on the name plate of the device.
•Do not place the power cord near heat sources such as heaters or radiators,
and do not excessively bend or otherwise damage the cord, place heavy
objects on it, or place it in a position where anyone could walk on, trip over,
or roll anything over it.
• Be sure to connect to an appropriate outlet with a protective grounding
connection. Improper grounding can result in electrical shock.
• Do not open the device or attempt to disassemble the internal parts or
modify them in any way. The device contains no user-serviceable parts. If it
should appear to be malfunctioning, discontinue use immediately and have
it inspected by qualified Yamaha service personnel.
• Do not expose the device to rain, use it near water or in damp or wet
conditions, or place containers on it containing liquids which might spill
into any openings. If any liquid such as water seeps into the device, turn off
the power immediately and unplug the power cord from the AC outlet. Then
have the device inspected by qualified Yamaha service personnel.
• Never insert or remove an electric plug with wet hands.
• If the power cord or plug becomes frayed or damaged, or if there is a
sudden loss of sound during use of the device, or if any unusual smells or
smoke should appear to be caused by it, immediately turn off the power
switch, disconnect the electric plug from the outlet, and have the device
inspected by qualified Yamaha service personnel.
• If this device should be dropped or damaged, immediately turn off the
power switch, disconnect the electric plug from the outlet, and have the
device inspected by qualified Yamaha service personnel.
CAUTION
Always follow the basic precautions listed below to avoid the possibility of physical injury to you or others, or
damage to the device or other property. These precautions include, but are not limited to, the following:
• Remove the electric plug from the outlet when the device is not to be used
for extended periods of time, or during electrical storms.
• When removing the electric plug from the device or an outlet, always hold
the plug itself and not the cord. Pulling by the cord can damage it.
• Before moving the device, remove all connected cables.
• When setting up the device, make sure that the AC outlet you are using is
easily accessible. If some trouble or malfunction occurs, immediately turn
off the power switch and disconnect the plug from the outlet. Even when the
power switch is turned off, electricity is still flowing to the product at the
minimum level. When you are not using the product for a long time, make
sure to unplug the power cord from the wall AC outlet.
• If the device is mounted in an EIA standard rack, carefully read the section
“Precautions when rack-mounting the unit” on page 6. Inadequate
ventilation can result in overheating, possibly causing damage to the
device(s), malfunction, or even fire.
• Do not use the device in a confined, poorly-ventilated location. If this
device is to be used in a small space other than an EIA-standard rack, make
sure that there is adequate space between the device and surrounding walls
or other devices: at least 10cm at the sides, 15cm behind and 40cm above.
Inadequate ventilation can result in overheating, possibly causing damage
to the device(s), or even fire.
• Do not expose the device to excessive dust or vibrations, or extreme cold
or heat (such as in direct sunlight, near a heater, or in a car during the day)
to prevent the possibility of panel disfiguration or damage to the internal
components.
•Do not place the device in an unstable position where it might accidentally
fall over.
• Do not block the vents. This device has ventilation holes at the front/rear to
prevent the internal temperature from becoming too high. In particular, do
not place the device on its side or upside down. Inadequate ventilation can
result in overheating, possibly causing damage to the device(s), or even fire.
• Do not use the device in the vicinity of a TV, radio, stereo equipment,
mobile phone, or other electric devices. Doing so may result in noise, both
in the device itself and in the TV or radio next to it.
• Before connecting the device to other devices, turn off the power for all
devices. Before turning the power on or off for all devices, set all volume
levels to minimum.
• Use only speaker cables for connecting speakers to the speaker jacks. Use
of other types of cables may result in fire.
• Do not place the device in a location where it may come into contact with
corrosive gases or salt air. Doing so may result in malfunction.
• Inspect the cooling fan air filter and clean it periodically (see the reference
manual (PDF file)). Dust and dirt can seriously degrade the effectiveness of
the cooling fan and result in malfunction or fire.
• Remove the power plug from the AC outlet when cleaning the device.
• When turning on the AC power in your audio system, always turn on the
device LAST, to avoid speaker damage. When turning the power off, the
device should be turned off FIRST for the same reason.
