Electromagnetic compatibility (EMC) for side-mounted goggles

Portable and mobile RF communications equipment can affect the VisualEyes™ system. Install and operate VisualEyes™
according to the EMC information presented in this chapter.
VisualEyes™ has been tested for EMC emissions and immunity as a standalone VisualEyes™ . Do not use VisualEyes™ adjacent
to or stacked with other electronic equipment. If adjacent or stacked use is necessary, the user should verify normal operation in the
configuration.
The use of accessories, transducers and cables other than those specified, with the exception of servicing parts sold by
Interacoustics as replacement parts for internal components, may result in increased EMISSIONS or decreased IMMUNITY of the
device.
Anyone connecting additional equipment is responsible for making sure the system complies with the IEC 60601-1-2 standard.
Guidance and manufacturer's declaration - electromagnetic emissions
VisualEyes™ is intended for use in the electromagnetic environment specified below. The customer or the user of
VisualEyes™ should assure that it is used in such an environment.

Recommended separation distances between portable and mobile RF communications equipment and VisualEyes™.
VisualEyes™ is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer
or the user of VisualEyes™ can help prevent electromagnetic interferences by maintaining a minimum distance between portable
and mobile RF communications equipment (transmitters) and VisualEyes™ as recommended below, according to the maximum
output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be
estimated using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer.
Note 1 At 80 MHz and 800 MHZ, the higher frequency range applies.
Note 2 These guidelines may not apply to all situations. Electromagnetic propagation is affected by absorption and reflection from
structures, objects and people.

Electromagnetic environment - guidance
VisualEyes™ uses RF energy only for its internal function.
Therefore, its RF emissions are very low and are not likely to cause
any interference in nearby electronic equipment.
VisualEyes™ is suitable for use in all commercial, industrial,
business, and residential environments.
