may cause electric shocks.
Handling caution
• Do not insert your hand or fingers into disk slot of this unit. Failure to observe this may
cause injury.
• Do not insert foreign materials such as metal or paper into disk slot 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.
• Avoid pulling the connected cables to prevent injuries or damage to the unit by causing it to
fall.
• Do not operate the unit if the sound is distorting. Prolonged use in this condition could
cause overheating and result in fire.
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.
• Keep batteries away from children. A child could accidentally swallow a battery. Failure to
observe this may also cause inflammation due to battery fluid leaks.
• Do not put in a pocket or bag, carry, or store batteries together with pieces of metal. The
battery could short, burst, or leak, causing a fire or injury.
• Always make sure all batteries are inserted in conformity with the +/- polarity markings.
Failure to do so might result in a fire, burns, or inflammation due to fluid leaks.
• When the batteries run out, or if the unit is not to be used for a long time remove the
batteries from the unit to prevent possible leakage of the battery fluid.
• When storing or discarding batteries, insulate the terminal area by applying tape, or some
other protection. Mixing them with other batteries or metal objects can cause a fire, burns,
or inflammation due to fluid.
