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.
Guidance and manufacturer's declaration - electromagnetic emissions
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.

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.
