Safety Precautions
The lightning flash with the arrowhead symbol in an equilateral triangle is intended to alert the user
to the presence of non-insulated “dangerous voltage” inside the appliance that may be of sufficient
magnitude to constitute a risk of electric shock.
The exclamation point within an equilateral triangle is intended to alert the user to the presence of
important operating and maintenance (servicing) instructions in the literature accompanying the
