  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:
    1. Reorient or relocate the receiving antenna.
    2. Increase the separation between the equipment and the receiver.
    3. Connect the equipment into an outlet on a circuit different from that to which the receiver is connected.
    4. 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.

  24. RF Power: <10dB
  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:
Duration, per day in hours Sound Level dBA, Slow Response Typical Example
8 90 Duo in small club
6 92  
4 95 Subway Train
3 97  
2 100 Very loud classical music
1.5 102  
1 105 Craig screaming at Troy about deadlines
