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

Group 1
The easyScreen 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.

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