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 con-

nection (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 equip-

ment 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 danger-

ous exposure to high sound pressure levels, it is recommended that all 

persons exposed to equipment capable of producing high sound pres-

sure 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:
