6.

  Clean only with a 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 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.

WARNING

CAUTION

The lightning flash with arrowhead symbol within  

an equilateral triangle is intended to alert the user  

to the prescence of uninsulated “dangerous voltage”  

within the product’s enclosure, that may be of significant 

magnitude to constitute a risk of electric shock to persons.

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 exclamation point within an equilateral triangle is  

intended to alert the user of the prescence of important  

operating and maintaining (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.

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.

ATTENTION

 —

 Le présent appareil numérique n’émet pas de bruits radioélectriques 

dépassant las limites applicables aux appareils numériques de class A/de class B 

(selon le cas) prescrites dans le réglement sur le brouillage radioélectrique édicté 

par les ministere des communications du Canada.

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:
