Interacoustics AA222 Instructions For Use Manual page 183

AA222 Руководство по эксплуатации – RU
Portable and mobile RF communications equipment can affect the AA222. Install and operate the AA222
according to the EMC information presented in this chapter. The AA222 has been tested for EMC emissions
and immunity as a standalone AA222. Do not use the AA222 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
The AA222 is intended for use in the electromagnetic environment specified below. The customer or the user of the
AA222 should assure that it is used in such an environment.

Recommended separation distances between portable and mobile RF communications equipment and the AA222.
The AA222 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the AA222 can help prevent electromagnetic interferences by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the AA222 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.

Electromagnetic environment - guidance
The AA222 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.
The AA222 is suitable for use in all commercial, industrial,
business, and residential environments.
