Yamaha R-N803 Manuel Du Propriétaire

- There is a loss of sound during use.
- There is a crack or damage in the unit.
Continued use could cause electric shocks, a fire, or 

malfunctions. Immediately request an inspection or repair from 

the dealer where you purchased the unit or from qualified 

Yamaha service personnel.

• Be careful not to drop or apply strong impact to this unit. If you 

suspect the unit may have been damaged due to dropping or 

impact, immediately turn off the power and pull the power plug 

from the AC outlet. Failure to observe this may cause electric 

shocks, a fire, or malfunctions. Immediately request an 

inspection from the dealer where you purchased the unit or from 

qualified Yamaha service personnel.

■

• 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.

■

• 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 top/bottom 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 30 cm (11-3/4 in) on top, 20 cm 

(7-7/8 in) on the sides, and 20 cm (7-7/8 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 place the unit in a location 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 turn over or 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.

• When transporting or moving the unit always use two or more 

people. Attempting to lift the unit by yourself may damage your 

back, result in other injury, or cause damage to the unit itself.

■

• Do not use the unit/speakers or headphones 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.

■

• Remove the power plug from the AC outlet when cleaning the 

unit. Failure to observe this may cause electric shocks.

■

• Do not insert foreign materials such as metal or paper into the 

ventilation holes 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 / then turn off any amplifiers and 

receivers and request an inspection from the dealer where you 

purchased the unit or from qualified Yamaha service personnel.

• Do not rest your weight on the unit or place heavy objects on it. 

Avoid applying excessive force to the buttons, switches or 

connectors. Failure to observe the above may cause injury or 

unit damage.

• Avoid pulling the connected cables to prevent injuries or 

damage to the unit by causing it to fall.

■

• 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 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 remote control 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.

Do not touch the surface marked with 

this label.

The surface may become hot during 

operation.
