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.

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 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:
