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 o 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

dierent 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.

3.

This device complies with FCC radiation exposure limits set

forth for an uncontrolled environment. This device should be

installed and operated with minimum distance 20cm between

the radiator & your body.

4.

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.

5.

This device complies with Industry Canada licence-exempt RSS

standard(s).

Operation is subject to the following two conditions:

() this device may not cause interference, and

Le présent appareil est conforme aux CNR d’Industrie

Canada applicables aux appareils radio exempts de licence.

L’exploitation est autorisée aux deux conditions suivantes:

() l’appareil ne doit pas produire de brouillage, et

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

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

compromettre le fonctionnement.

6.

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 suciently 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:
