IMPORTANT SAFETY INSTRUCTIONS

 

Explanation of graphic symbols:

The lightning flash with arrowhead 
symbol within an equilateral triangle is 
intended to alert you 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.

equilateral triangle is intended to alert 
you to the presence of important
