CAUTION
This content indicates “risk of injury.”
Power supply/power cord
• Do not use an AC outlet where the power plug
fits loosely when inserted. Failure to observe
this may cause a fire, electric shocks, or burns.
• When removing the electric plug from the unit or
an AC outlet, always hold the plug itself and not
the cord. Pulling by the cord can damage it and
cause electric shocks or a fire.
• Insert the power plug firmly all the way into the
AC outlet. Using the unit when it is not plugged
in sufficiently can cause dust to accumulate on
the plug, causing a fire or burns.
Installation
• Do not place the unit in an unstable position
where it might accidentally drop or fall over and
cause injuries.
• When installing this unit:
- 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 location.
Failure to observe the above may trap heat
inside the unit, causing a fire or malfunctions.
Ensure that there is adequate space around the
unit: at least 10 cm (3-7/8 in) on top, 10 cm
(3-7/8 in) on the sides, and 10 cm (3-7/8 in) on
the rear.
• Ensure that the top is facing upwards. Failure to
observe this may cause malfunctions or for the
unit to fall and cause injury.
• Do not install the unit in places where it may
come into contact with corrosive gases or salt
air. Doing so may result in malfunction.
• Avoid being near the unit during a disaster,
such as an earthquake. Since the unit may fall
and cause injury, quickly move away from the
unit and go to a safe place.
• Before moving this unit, be sure to turn off the
power switch and disconnect all connection
cables. Failure to observe this may damage the
cables or cause you or someone else to trip
and fall.
Hearing loss
• Before connecting the unit to other devices,
turn off the power for all devices. Failing to do
so may result in hearing loss, electric shock, or
device damage.
• When turning on the AC power in your audio
system, always turn on the amplifier or receiver
LAST, to avoid hearing loss and speaker
damage. When turning the power off, the
amplifier or receiver should be turned off FIRST
for the same reason. Failure to observe the
above may cause hearing impairment or
speaker damage.
Maintenance
• Remove the power plug from the AC outlet
when cleaning the unit. Failure to observe this
may cause electric shocks.
Handling caution
• Do not insert foreign materials such as metal or
paper into panel slits of this unit. Failure to
observe this may cause a fire, electric shocks,
or malfunctions. If foreign material gets into the
unit, immediately shut off the power and pull the
power plug from the AC outlet and request an
inspection from the dealer where you
purchased the unit or from qualified Yamaha
service personnel.
• Do not do the following:
- stand on or sit on the equipment.
- put heavy items on top of the equipment.
- place the equipment in a stack.
- apply unreasonable force to buttons,
switches, input/output terminals, etc.
- hang on the equipment.
- lean against the equipment.
• Avoid pulling the connected cables to prevent
injuries or damage to the unit.
Battery use
• Always replace all batteries at the same time.
Do not use new batteries together with old
ones. Using new ones with old ones could
cause a fire, burns, or inflammation due to fluid
leaks.
• Do not use batteries other than specified
batteries. Doing so cause fire, burns, or
inflammation due to leakage.
• Do not mix battery types, such as alkaline
batteries with manganese batteries, or batteries
from different makers, or different types of
batteries from the same maker, since this can
cause a fire, burns, or inflammation due to fluid
leaks.
