Precautions
On safety
• Should any liquid or solid object fall
into the unit, unplug the unit and
have the unit checked by qualified
personnel before operating it any
further.
On power sources
• Before operating the unit, be sure that
the operating voltage of your unit is
identical with that of your local

unit which might block the
ventilation holes and cause
malfunctions.
On cleaning the cabinet

with a soft cloth lightly moistened
with a mild detergent solution. Do
not use any type of abrasive pad,
scouring powder or solvent such as
alcohol or benzine.
On repacking
