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 is 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 a 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. Use the mains plug to disconnect the apparatus 

 

from the mains. 

16. WARNING: To reduce the risk of fire or electric 

 

shock, do not expose this apparatus to 

 

rain or moisture.

17. Do not expose this equipment to dripping or 

 

splashing and ensure that no objects filled with 

 

liquids, such as vases, are placed on the equipment.

18. The mains plug of the power supply cord shall 

 

remain readily operable.

19. Do not connect the unit’s output to any other 

 

voltage source such as battery, mains source, or

 

power supply, regardless of whether the unit is

 

turned on or off.

20. Do not remove the top (or bottom) cover. Removal

 

of the cover will expose hazardous voltages. There

 

are no user serviceable parts inside and removal

 

may void the warranty.

21. An experienced user shall always supervise this

 

professional audio equipment, especially if 

 

inexperienced adults or minors are using the 

 equipment.

22. The US National Differences clause 16.3 requires

 

that network cables must be flame rated VW-1.

Before using the device, be sure to carefully read the safety instructions. Keep this document
