lateral triangle, is intended to alert the user to the presence 
of  uninsulated  “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 in-
tended to alert the user to the presence of important operat-
ing and maintenance (servicing) instructions in the literature 
accompanying the appliance.
