The lightning flash with 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 the presence of important operating and maintenance (servicing) 
instructions in the literature accompanying the appliance. 

WARNING 

TO REDUCE THE RISK OF FIRE OR ELECTRIC SHOCK, DO 
NOT EXPOSE THIS APPLIANCE TO RAIN OR MOISTURE. 

This product was designed and manufactured to meet strict quality and safety standards.  There are, however, some

wet basement, or near a swimming pool, etc. 

6. 

Carts and Stands

 – The appliance should be used only with a cart or stand that is recommended by the manufacturer.  An appliance and cart 

combination should be moved with care.  Quick stops, excessive force, and uneven surfaces may cause the appliance and cart combination 
to overturn. 

7. 

Wall or Ceiling Mounting

 – The appliance should be mounted to a wall or ceiling only as recommended by the manufacturer. 

8. 

Ventilation

 – The appliance should be situated so that its location or position does not interfere with its proper ventilation.  For example, the 

appliance should not be situated on a bed, sofa, rug, or similar surface that may block the ventilation openings; or, placed in a built-in 
installation, such as a bookcase or cabinet that may impede the flow of air through the ventilation openings. 

9. 

Heat

 – The appliance should be situated away from heat sources such as radiators, heat registers, stoves, or other appliances (including

amplifiers) that produce heat. 

10. 

Power Sources

 – The appliance should be connected to a power supply only of the type described in the operating instructions or as marked 

on the appliance. 

11. 

Grounding or Polarization

 – Precautions should be taken so that the grounding or polarization means of an appliance is not defeated. 

12. 

Power-Cord Protection

 – Power- supply cords should be routed so that they are not likely to be walked on or pinched by items placed upon 

or against them, paying particular attention to cords at plugs, convenience receptacles, and the point where they exit from the appliance. 

13. 

Cleaning

 – The appliance should be cleaned only as recommended by the manufacturer. 

14. 

Power Lines

 – An outdoor antenna should be located away from the power lines. 

15. 

Nonuse Periods

 – The power cord of the appliance should be unplugged from the outlet when left unused for a long period of time. 

16. 

Object and Liquid Entry

 – Care should be taken so that objects do not fall and liquids are not spilled into the enclosure through openings. 

17. 

Damage Requiring Service

 – The appliance should be serviced by qualified service personnel when: 

 

A.  The Power-supply cord or the plug has been damaged; or 

 

B.  Objects have fallen, or liquid has spilled into the appliance; or 

 

C.  The appliance has been exposed to rain; or 

 

D.  The appliance does not appear to operate normally or exhibits a marked change in performance; or 

 

E.  The appliance has been dropped, or the enclosure damaged. 

18.
