When Installing the Unit

• Never plug in nor remove the power supply plug with wet hands, as doing so may cause electric shock.

• When unplugging the power supply cord, be sure to grasp the power supply plug; never pull on the cord

itself. Operating the unit with a damaged power supply cord may cause a fire or electric shock.

• When moving the unit, be sure to remove its power supply cord from the wall outlet. Moving the unit with the

power cord connected to the outlet may cause damage to the power cord, resulting in fire or electric shock.
When removing the power cord, be sure to hold its plug to pull. 

• Do not block the ventilation slots in the unit's cover. Doing so may cause heat to build up inside the unit and

result in fire.

• Avoid installing the unit in humid or dusty locations, in locations exposed to the direct sunlight, near the heaters,

or in locations generating sooty smoke or steam as doing otherwise may result in fire or electric shock. 

• To avoid electric shocks, be sure to unplug the unit's power supply cord when connecting speakers.

• Be sure to follow the instructions below when rack-mounting the unit. Failure to do so may cause a fire or

personal injury.
· Install the equipment rack on a stable, hard floor. Fix it with anchor bolts or take other arrangements to

prevent it from falling down.

· When connecting the unit's power cord to an AC outlet, use the AC outlet with current capacity allowable to

the unit.

· No rack-mounting screws are supplied with the unit. Separately prepare the appropriate screws for the

rack.

• Keep the amplifier over 10 cm (3.94") away from

objects that may obstruct air flow to prevent the unit's
internal temperature rise.

When the Unit is in Use 

• Do not place heavy objects on the unit as this may cause it to fall or break which may result in personal

injury and/or property damage. In addition, the object itself may fall off and cause injury and/or damage.

• Make sure that the volume control is set to minimum position before power is switched on. Loud noise

produced at high volume when power is switched on can impair hearing. 

• Do not operate the unit for an extended period of time with the sound distorting. This is an indication of a

malfunction, which in turn can cause heat to generate and result in a fire.

• If dust accumulates on the power supply plug or in the wall AC outlet, a fire may result. Clean it periodically.

In addition, insert the plug in the wall outlet securely.

• Switch off the power, and unplug the power supply plug from the AC outlet for safety purposes when

cleaning or leaving the unit unused for 10 days or more. Doing otherwise may cause a fire or electric shock.

The lighting flash with arrowhead symbol, within an equilateral triangle, is intended to alert the user
to the presence of uninsulated "dangerous voltage" within the product's enclosure that may be of
sufficient magnitude to constitute a risk of electric shock to persons.
