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:
Power supply/Power cord
• 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
• 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.
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:
Power supply/Power cord
• 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.
Location
• 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.
