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
• 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.
• 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. 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.
• Check the electric plug periodically and remove any dirt or
dust which may have accumulated on it.
• Be sure to connect to an appropriate outlet with a protective
grounding connection. Improper grounding can result in
electrical shock, damage to the device(s), or even ﬁre.
Do not open
• This device contains no user-serviceable parts. Do not
open the device or attempt to disassemble the internal
parts or modify them in any way. 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 on it any containers (such as vases,
bottles or glasses) containing liquids which might spill into any
openings. If any liquid such as water seeps into the device,
turn off the power immediately and unplug the power cord from
the AC outlet. Then have the device inspected by qualiﬁed
Yamaha service personnel.
• Never insert or remove an electric plug with wet hands.
• Do not put burning items, such as candles, on the unit. A
burning item may fall over and cause a ﬁre.
If you notice any abnormality
• When one of the following problems occur, immediately turn off
the power switch and disconnect the electric plug from the outlet.
Then have the device inspected by Yamaha service personnel.
– The power cord or plug becomes frayed or damaged.
– It emits unusual smells or smoke.
– Some object has been dropped into the instrument.
– There is a sudden loss of sound during use of the device.
• 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.
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
• 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.
• Remove the electric plug from the outlet when the device is not to
be used for extended periods of time, or during electrical storms.
• 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/
bottom/sides 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.
• When attempting to dissipate heat on the device, when
– Do not cover it with any cloth.
– Do not install it on a carpet or rug.
– Make sure the top surface faces up; do not install on its
sides or upside down.
– Do not use the device in a conﬁned, poorly-ventilated
Inadequate ventilation can result in overheating, possibly
causing damage to the device(s), or even ﬁre.
Make sure that there is adequate space around the device: at
least 10 cm above, 1 cm below the bottom surface, 10 cm at
the sides and 10 cm behind.
• Do not place the device in a location where it may come into
contact with corrosive gases or salt air. Doing so may result in
• 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 for rack mounting". Inadequate
ventilation can result in overheating, possibly causing damage
to the device(s), malfunction, or even ﬁre.

Precautions for rack mounting
This unit is rated for operation at ambient temperatures ranging
from 0 to 40 degrees Celsius. If the device is mounted with
other devices in an EIA standard equipment rack, internal
temperatures can exceed the speciﬁed upper limit, resulting in
impaired performance or failure. If the device is mounted in a
rack, always observe the following requirements to avoid heat
• If the device is mounted in a rack with other devices that
generate a signiﬁcant amount of heat, such as a power
ampliﬁer, leave more than 1U of space between the device
and other devices (both above and below). Also, make sure to
either leave any open spaces uncovered or install appropriate
ventilating panels to minimize the possibility of heat buildup.
• To ensure sufﬁcient airﬂow, leave the rear of the rack open and
position it at least 10 centimeters from walls or other surfaces.
If you've installed a fan kit, there may be cases in which
closing the rear of the rack will produce a greater cooling
effect. Refer to the rack and fan unit manual for details.
The model number, serial number, power requirements, etc.,
may be found on or near the name plate, which is at the
bottom of the unit.
You should note this serial number in the space provided
