The lightning flash with an arrowhead symbol, within an
equilateral triangle, is intended to alert the user to the
presence of un-insulated "dangerous voltage" within the
product's enclosure that may be of sufficient magnitude to
constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is
intended to alert the user to presence of important
operating and maintenance (servicing) instructions in the
literature accompanying the appliance.
