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.
• Use only the supplied 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
• 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.
• Turn the unit ON or OFF using only the front-panel POWER switch. Turning the unit ON or
OFF by plugging or unplugging the power cord, using a switch on a power tap, a breaker
switch, or similar external means can result in damage.
Location
• Before moving the device, remove all connected cables.
• If this device is to be mounted in an EIA-standard rack, leave the back of the rack open and
make sure that it is at least 10 cm away from walls or surfaces. Under these conditions two
of these devices can be rack-mounted directly on top of each other. Inadequate ventilation
can result in overheating, possibly causing damage to the device(s), 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 10 cm behind and
10 cm 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.
