PRECAUTIONS & SAFETY INSTRUCTIONS

SAFETY INSTRUCTIONS

1. AVOID EXCESSIVE HEAT, HUMIDITY, DUST

AND VIBRATION

Keep the unit away from locations where it is likely to be

exposed to high temperatures or humidity—such as

near radiators, stoves, etc. Also avoid locations which

are subject to excessive dust accumulation or vibration

which could cause mechanical damage.

2. INSTALL THE UNIT IN WELL-VENTILATED

CONDITION

The openings on the cabinet assure proper ventilation

of the unit. If these openings are obstructed, the

temperature inside the cabinet will rise rapidly.

Therefore, avoid placing objects against these

openings, and install the unit in well-ventilated

condition. Make sure to allow a space of at least 10

cm behind and on the both sides and at least 20 cm

above the top panel of the unit. Otherwise it may not

only damage the unit, but also cause fire.

3. KEEP THE AC POWER PLUG

DISCONNECTED DURING VACATION ETC.

When not planning to use this unit for long periods of

time (ie., vacation, etc.), disconnect the AC power

plug from the wall outlet.

4. AVOID PHYSICAL SHOCKS

Strong physical shocks to the unit can cause damage.

Handle it with care.

5. DO NOT OPEN THE UNIT OR ATTEMPT

REPAIRS OR MODIFICATIONS YOURSELF

This product contains no user-serviceable parts. Refer

all maintenance to qualified Yamaha service personnel.

Opening the unit and/or tampering with the internal

circuitry will make servicing difficult and will endanger

you and your unit.

6. MAKE SURE POWER IS OFF BEFORE

MAKING OR REMOVING CONNECTIONS

Always turn power OFF prior to connecting or

disconnecting cables. This is important to prevent

damage to the unit itself as well as other connected

equipment.

7. HANDLE CABLES CAREFULLY

Always plug and unplug cables—including the AC

cord—by gripping the connector, not the cord.

8. CLEAN WITH A SOFT DRY CLOTH

Never use solvents such as benzine or thinner to clean

the unit. Wipe clean with a soft, dry cloth.

9. ALWAYS USE THE CORRECT POWER

SOURCE

Make sure that the power source voltage specified on

the rear panel matches your local AC mains supply.

10.KEEP AWAY FROM TUNERS

Digital signals generated by the unit may interfere with

other equipment such as tuners, receivers or TVs. Move

the system farther away from such equipment if

interference is observed.

unit in the space below.
