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 ma-

gnitude 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: 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.

20.

 The use of apparatus is in moderate climates.

21.

 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.

22.

 This apparatus does not exceed the Class A/Class B (whichever is appli-

cable) 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 radioélec-

triques 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.

23.

 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:

day in hours
