Interacoustics AD226 Instructions For Use Manual page 367

5.3 Electromagnetic Compatibility (EMC)
Portable and mobile RF communications equipment can affect the AD226. Install and operate the AD226 according to the EMC
information presented in this chapter.
The AD226 has been tested for EMC emissions and immunity as a standalone instrument. Do not use the AD226 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 AD226 is intended for use in the electromagnetic environment specified below. The customer or the user of the AD226
should assure that it is used in such an environment.

Recommended separation distances between portable and mobile RF communications equipment and the AD226.
The AD226 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The customer or the user of the AD226 can help prevent electromagnetic interferences by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the AD226 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 AD226 is intended for use in the electromagnetic environment specified below. The customer or the user of the
AD226 should assure that it is used in such an environment.

Electromagnetic environment - guidance
The AD226 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 AD226 is suitable for use in all commercial, industrial, business,
and residential environments.
