power source as marked on the unit.
GROUNDING OR POLARIZATION This unit is equipped with
a polarized AC power cord plug (a plug having one blade wider
than the other). This plug will fit into the power outlet only one
way. This is a safety feature. If you are unable to insert the
plug fully into the outlet, try reversing the plug. If the plug still
fails to fit, contact your electrician to have a suitable outlet
installed. Do not defeat the safety purpose of the polarized
NON USE PERIODS Always turn the unit off and unplug when
it is not being used or left unattended for long periods of time.
OBJECT AND LIQUID ENTRY Never push objects of any
kind into the unit through the cabinet slots as they may touch
dangerous voltage points or short out parts that could result
in a fire or electric shock. Never spill liquid of any kind on the
unit.
CLEANING Unplug the unit from the wall outlet before
cleaning or polishing it. Do not use liquid cleaners, aerosol
cleaners, gasoline or other flammable fluid. Clean the exterior
of the unit with a slightly damp cloth.
