Important Safety Instructions

To reduce the risk of fire or electric shock, do not expose this apparatus to rain or moisture.

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.

2.  Keep these instructions.
3.  Heed all warnings.
4.  Follow all instructions.
5.  Do not use this apparatus near water.
6.  Clean only with dry cloth.
7.  Do not block any ventilation openings. Install in accordance with the manufacturer’s instructions.
8.  Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including 

amplifiers) that produce heat.

9.  Do not defeat the safety purpose of the polarized or grounding-type plug. A polarized plug has two blades with one 

wider than the other. A grounding type plug has two blades and a third grounding prong. The wide blade or the 
third prong are provided for your safety. If the provided plug does not fit into your outlet, consult an electrician for 
replacement of the obsolete outlet.

10. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the 

point where they exit from the apparatus.

11.  Only use attachments/accessories specified by the manufacturer.
12. Use only with the cart, stand, tripod, bracket, or table specified by the manufacturer, or sold with the apparatus. 

When a cart is used, use caution when moving the cart/apparatus combination to avoid injury from tip-over.

13. Unplug this apparatus during lightning storms or when unused for long periods of time.
14. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged 

in any way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the 
apparatus, the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.

15. The MAINS plug or an appliance coupler is used as the disconnect device, so the disconnect device shall remain 

readily operable.

16. This apparatus has been designed with Class-I construction and must be connected to a mains socket outlet with 

a protective earthing connection (the third grounding prong).
