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.

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:
