non-insulated “dangerous voltage” within the product’s enclosure that may be of sufficient magnitude to constitute a 

risk of electric shock.

  - Warning: To reduce the risk of electric shock, do not remove the cover (or back) as there are no user-serviceable 

parts inside. Refer servicing to qualified personnel.

  - The exclamation point within an equilateral triangle is intended to alert the user to the presence of important 

operating and maintenance instructions in the literature accompanying the appliance.
