NOTE:

 This equipment has been tested and found to comply with the limits 

for a Class A digital device, pursuant to part 15 of the FCC Rules. These  

limits are designed to provide reasonable protection against harmful 

interference when the equipment is operated in a commercial environment. 

This equipment generates, uses, and can radiate radio frequency energy 

and, if not installed and used in accordance with the instruction manual, 

may cause harmful interference to radio communications. Operation  

of this equipment in a residential area is likely to cause harmful interference 

in which case the user will be required to correct the interference at his  

own expense.

 

WARNING:

 Operation of DRM18S in a residential environment could cause 

radio interference.

 

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.

24.

  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.

25.

  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
