Precaution points and notices
Below-described precaution points and notices are to prevent self injury and property damage. Before
operating the amplifier, read this manual first to get known of potential safety hazard and to understand the
meaning of the precaution points and notices.
DO NOT
install or mount the amplifier on unstable objects, such as on the rickety table or the slanted
surface. It may result in the amplifier to fall and cause body injury and/or property damage.
Be sure to ground
to the safety ground (earth) terminal to avoid electric shock. Never ground to a gas pipe.
Use the amplifier only with appropriate voltage specified on the amplifier. Using the voltage higher than
specified may cause fire or electric shock.
DO NOT
cut, twist, damage, nor modify the power supply cord. In addition, avoid using the power cord
close to heaters, and don’t place heavy object, including the amplifier itself, on the power cord, for it may
cause fire or electric shock.
DO NOT
expose the amplifier to rain or the environment where water or other liquids may be splashed,
doing this, it may cause fire or electric shock.
DO NOT
remove nor plug in the power supply plug with wet hands, for it may cause electric shock.
Be sure to grasp the power supply plug when unplugging. DO NOT pull on the cord itself. Operating the
amplifier with damaged power supply cord may cause fire or electric shock.
Avoid
installing the amplifier in humid or dusty places, the area exposed to the direct sunlight, locations
generating smoke or steam, or the spot near the heaters. It may result in fire or electric shock.
When moving the amplifier, be sure to remove its power supply cord from the wall outlet. Moving the
amplifier with the power cord connected to the outlet may cause damage to the power cord, and resulting
in fire or electric shock. When removing the power cord, be sure to grasp its plug to pull.
DO NOT
Block the ventilation slots of the amplifier chassis. It will cause the temperature rising and may
result fire.
