Important Safety Instructions

WARNING:
To reduce the risk of fire or electric shock, do not expose this appliance to rain or moisture.
CAUTION:
Use of controls or adjustments or performance of procedures other than those specified may result in hazardous radiation 
exposure.

CAUTION

RISK OF ELECTRIC SHOCK

DO NOT OPEN

WARNING: SHOCK HAZARD - DO NOT OPEN

AVIS: RISQUE DE CHOC ÉLECTRIQUE - NE PAS OUVRIR

The lightning flash with the arrowhead symbol within an equilateral triangle, is intended to alert you to the presence 

of uninsulated dangerous voltages within the product’s enclosure that may be of sufficient magnitude to constitute a 
risk of electric shock. 

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.

1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Clean only with dry cloth.
6. Do not use this apparatus near water.
7. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers) that 
produce heat.
8. 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.
9. Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point 

where they exit from the apparatus.
10. Only use attachments/accessories specified by the manufacturer.
11. 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.
12. Unplug this apparatus during lightning storms or when unused for long periods of time.
13. 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.
14. No naked flames, such as lighted candles, should be placed on the apparatus.

WARNING: Excessive sound pressure levels from earphones and headphones can cause hearing loss.
