Electromagnetic Compatibility (Emc) - Interacoustics MT10 Manual De Instrucciones

5.1

Electromagnetic Compatibility (EMC)

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

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

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