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.
• Use only the included power cord.
• 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.
• 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.
• 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.
• If you use the metal socket on the subwoofer for mounting of a satellite
speaker, use a pole no longer than 90cm (35.4") with an outer diameter of
35mm (1-3/8"). Use of any other size pole may cause the device to fall, and
result in injury or damage to the internal components.
• When transporting or moving the device, always use two or more people.
Attempting to lift the device by yourself may damage your back, result in
other injury, or cause damage to the device itself.
• Before moving the device, remove all connected cables.
• 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 here is adequate space between the device and surrounding walls or
other devices: at least 30cm at the sides, 30cm behind and 30cm above.
Inadequate ventilation can result in overheating, possibly causing damage to
the device(s), or even fire.
• Do not use the speaker’s handles for suspended installation. Doing so can
result in damage or injury.
• 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.
• 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.
