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.
If you intend to use the device in an area other than in the one you
purchased, the included power cord may not be compatible. Please check
with your Yamaha dealer.
• 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.
• 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.
• When transporting or moving the device, do not hold the display.
Improper transportation can result in injury or damage to the device itself.
• Before moving the device, remove all connected cables.
• When setting up the product, 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.
• Avoid setting all equalizer controls and faders to their maximum.
Depending on the condition of the connected devices, doing so may cause
feedback and may damage the speakers.
• 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 top and 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.
