 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

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 Audio LLC could void the user's authority to 

operate the equipment under FCC rules.

WARNING

 — To reduce the risk of fire or electric shock,  

do not expose this apparatus to rain or moisture.

forth for an uncontrolled environment. This device should be 

installed and operated with minimum distance 20cm between 

the radiator & your body.

14.

  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

(2)  l’utilisateur de l’appareil doit accepter tout brouillage 

radioélectrique subi, même si le brouillage est susceptible d’en 

compromettre le fonctionnement.

16.

  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:
