The  lightning  flash  with  arrowhead  symbol,  within  an 
equilateral  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)

of  procedures  other  than  those 

specified

  may  result  in 

hazardous radiation exposure.

The apparatus shall not be exposed to dripping or splashing and that no objects 

filled

 with liquids, such as vases, 

shall be placed on the apparatus. The MAINS plug is used as the disconnect device, the disconnect device shall 
remain readily operable. 

Warning

: the user shall not place this apparatus in the
