Precautions

Danger
This sign reminds users of “dangerous voltage” on the

product.

Caution
This sign reminds users of important instructions

attached to the product.

Safety
guideline

In order to prevent electric shock, this equipment plug
shall not be used as conductor to extend power supply
line.

Do not block the equipment’s ventilation opening or put

other equipment on it.

Safety
guideline

Protect this equipment against rainwater or moisture so
as to avoid fire or electric shock.

Unpacking

After removing the amplifier from the carton, inspect for any exterior
damage to the unit. If damage is noted, notify the carrier at once so that a
claim can be justified. Save all packing material. This is important when
the claim is processed.

2

Ventilation

To offset heat generated by the unit, it is necessary to provide ample
ventilation around the unit. Avoid blocking or impeding the ventilation holes
on the unit. To prevent unnecessary problems, install the unit in a place
free from any vibrations, direct sunlight, humidity or dust circulation.

Prevent liquids or other materials to enter cabinet

If the unit gets wet or any foreign material enters the amplifier cabinet,
immediately disconnect the AC power cord and consult your dealer or
qualified technician.
