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:
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 all 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 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 to
provide better airflow. In such a situation, these devices can be stacked on top of
each other if necessary. Also, if this device is to be mounted with devices that
tend to generate heat, such as power amplifiers made by another manufacturer,
be sure to keep an adequate gap between this device and the heat-generating
devices, or install ventilation panels or forced ventilation fans to prevent high
temperatures from developing inside this device.
Inadequate ventilation can result in overheating, possibly causing damage to the
device(s), or even fire.
PRECAUTIONS
• Do not expose the device to rain, use it near water or in damp or wet conditions,
• 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
• If this device should be dropped or damaged, immediately turn off the power
• Do not use the device in a confined, poorly-ventilated location. If this device is
• Do not expose the device to excessive dust or vibrations, or extreme cold or heat
• Do not place the device in an unstable position where it might accidentally fall
• Do not block the vents. This device has ventilation holes at the front/rear to
• Do not use the device in the vicinity of a TV, radio, stereo equipment, mobile
