IMPORTANT SAFETY INSTRUCTIONS
Read these operating instructions carefully before using the unit. Follow the safety instructions on the unit and the safety precautions listed below.
Keep these operating instructions handy for future reference.
Safety
1. Power source—Connect the unit to a power source of the type de-
scribed in these instructions or as marked on the unit.
2. Polarization—The unit is equipped with a polarized power plug
where one blade is wider than the other. This safety feature ensures
that the plug fits into your household AC outlet only one way. If the
plug doesn’t fit one way, try reversing it. If the plug still doesn’t fit,
contact an electrician to replace the obsolete outlet. Do not attempt to
defeat the safety purpose of the plug.
3. Power cord protection—Route the AC power supply cord so that it
will not be walked on or pinched by items placed on or against it.
Never take hold of the plug or cord with wet hands. Always grasp the
plug body firmly when connecting and disconnecting it.
4. Overloading—When connecting the AC power supply cord, be care-
ful not to overload the household AC outlet, extension cord, or outlet
from any other device as this can result in fire or electric shock.
5. Nonuse periods—Turn the unit off when it is not in use. Unplug the
unit from the household AC outlet if it is not to be used for a long
time. Unplug the unit during lightning storms.
6. Attachments and accessories—Use only the attachments and ac-
cessories recommended in these operating instructions.

not install in a confined space such as a bookcase or cabinet. Allow
at least 10 cm (4 inches) clearance from the rear of the unit. To pre-
vent the risk of electric shock or fire due to overheating ensure cur-
tains and other materials do not obstruct the unit’s ventilation.

unit. Avoid exposing the unit to excessive smoke, dust, mechanical
vibration, and shock.

on walls or ceilings unless specified in the instruc-
tions.
