WARNING: When using electrical products, basic cautions should always be followed, including the following:
1. Read these instructions. 
2. Keep these instructions safe.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water. 
6. Clean only with a dry cloth.
7. Do not block any of the ventilation openings. Install in accordance with 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. An apparatus with Class I construction shall be connected to a mains socket outlet with a protective connection. 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 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 they exit from the apparatus.
11. Only use attachments/accessories provided 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. The mains plug or appliance coupler is used as the disconnect device and shall remain readily operable.

 

The user should allow easy access to any mains 

plug, mains coupler and mains switch used in conjunction with this unit thus making it readily operable. 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 when 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. Never break off the ground pin. Connect only to a power supply of the type marked on the unit adjacent to the power supply cord.
16. If this product is to be mounted in an equipment rack, rear support should be provided.
17. Note for UK only: If the colours of the wires in the mains lead of this unit do not correspond with the terminals in your plug‚ proceed as follows:
    a) The wire that is coloured green and yellow must be connected to the terminal that is marked by the letter E‚ the earth symbol‚ coloured green or
         coloured green and yellow.
    b) The wire that is coloured blue must be connected to the terminal that is marked with the letter N or the colour black.
    c) The wire that is coloured brown must be connected to the terminal that is marked with the letter L or the colour red.
18.This electrical apparatus should not be exposed to dripping or splashing and care should be taken not to place objects 
containing liquids, such as vases, upon the apparatus.
19. Exposure to extremely high noise levels may cause a permanent hearing loss. Individuals vary considerably in

 

susceptibility to noise-induced hearing loss, but nearly everyone will lose some hearing if exposed to sufficiently intense noise for a 
sufficient time.
    The U.S. Government’s Occupational Safety and Health Administration (OSHA) has specified the following permissible noise level 
exposures: According to OSHA, any exposure in excess of the above permissible limits could result in some hearing loss. Earplugs or 
protectors to the ear canals or over the ears must be worn when operating this amplification system in order to prevent a permanent 
hearing loss, if exposure is in excess of the limits as set forth above. To ensure against potentially dangerous exposure to high sound 
pressure levels, it is recommended that all persons exposed to equipment capable of producing high sound pressure levels such as this 
amplification system be protected by hearing protectors while this unit is in operation.
