WARNING

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.
Do not block this unit’s ventilation holes (cooling slits). This unit has ventilation holes on the side to prevent the internal temperature from becoming too high. Failure to observe this may trap heat inside the unit, causing a fire or malfunctions.
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 5 cm (2 in) on top, 5 cm (2 in) on the sides, and 5 cm (2 in) on the rear.
Do not install the unit in places where it may come into contact with corrosive gases or salt air or places that have excessive smoke or steam. Doing so may result in malfunction.
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 to trip and fall.
For proper installation of the outdoor antenna, make sure to have it done by the dealer from where you purchased the unit or by qualified service personnel. Failure to observe this may cause the installation to fall and result in injury. Installation requires special skills and experience.

Hearing loss

Do not use the unit for a long period of time at a high or uncomfortable volume level, since this can cause permanent hearing loss. If you experience any hearing loss or ringing in the ears, consult a physician.
Before connecting the unit to other devices, turn off the power for all devices. Also, before turning the power of all devices on or off, make sure that all volume levels are set to the minimum. 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 unit LAST, to avoid hearing loss and speaker damage. When turning the power off, the unit 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 before cleaning the unit. Failure to observe this 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.

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.
