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 ventilation openings. Install in accordance with the manu-

facturer’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 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. This apparatus shall not be exposed to dripping or splashing, and no object 

filled with liquids, such as vases or beer glasses, shall be placed on the 

apparatus.

16. Do not overload wall outlets and extension cords as this can result in a risk 

of fire or electric shock.

17. 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).

18. This apparatus has been equipped with a rocker-style AC mains power 

switch. This switch is located on the rear panel and should remain readily 

accessible to the user.

19.  The MAINS plug or an appliance coupler is used as the disconnect device, 

so the disconnect device shall remain readily operable.

20. NOTE: This equipment has been tested and found to comply with 

the limits for a Class B digital device, pursuant to part 15 of the FCC 

Rules. These limits are designed to provide reasonable protection 

against harmful interference in a residential installation. This equipment 

generates, uses, and can radiate radio frequency energy and, if not 

installed and used in accordance with the instructions, may cause 

harmful interference to radio communications. However, there is no 

guarantee that interference will not occur in a particular installation. 

If this equipment does cause harmful interference to radio or television 

reception, which can be determined by turning the equipment off and 

on, the user is encouraged to try to correct the interference by one or 

more of the following measures:

•  Reorient or relocate the receiving antenna.

•  Increase the separation between the equipment and the receiver.

•  Connect the equipment into an outlet on a circuit different from that

to which the receiver is connected.

•  Consult the dealer or an experienced radio/TV technician for help.

  CAUTION: Changes or modifications to this device not expressly approved 

by LOUD Technologies Inc. could void the user's authority to operate the 

equipment under FCC rules.

21. This apparatus does not exceed the Class A/Class B (whichever is 

applicable) limits for radio noise emissions from digital apparatus as set 

out in the radio interference regulations of the Canadian Department of 

Communications.

22. Exposure to extremely high noise levels may cause 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 period of time. The U.S. Government’s Occupational 

Safety and Health Administration (OSHA) has specified the permissible 

noise level exposures shown in the following chart.

  According to OSHA, any exposure in excess of these permissible limits 

could result in some hearing loss. 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 

use hearing protectors while the equipment is in operation. Ear plugs or 

protectors in the ear canals or over the ears must be worn when operating 

the equipment in order to prevent permanent hearing loss if exposure is in 

excess of the limits set forth here:

RISK OF ELECTRIC 

SHOCK. DO NOT OPEN

CAUTION: TO REDUCE THE RISK OF ELECTRIC SHOCK DO NOT REMOVE COVER (OR BACK)

NO USER-SERVICEABLE PARTS INSIDE. REFER SERVICING TO QUALIFIED PERSONNEL

The lightning flash with arrowhead symbol within an equilateral triangle is 

intended to alert the user to the presence of uninsulated "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 of 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 apparatus to rain or moisture.
