CAUTION
An all-pole mains switch with a contact separation of at least 3 mm in each pole shall be
incorporated in the electrical installation of the building.
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 direct
sunlight, near heaters, or in locations
generating sooty smoke or steam as doing
otherwise may result in fire or electric
shock.
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.
Contact your dealer as to cleaning. If dust •
is allowed to accumulate in the unit over a
long period of time, a fire or damage to the
unit may result.
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.
