5.1
Electromagnetic Compatibility (EMC)
Portable and mobile RF communications equipment can affect the MT10. Install and operate the MT10
according to the EMC information presented in this chapter.
The MT10 has been tested for EMC emissions and immunity as a standalone instrument. Do not use the
MT10 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+AMD1:2020, emission class B group.
Guidance and manufacturer's declaration - electromagnetic emissions
MT10 is intended for use in the electromagnetic environment specified below. The customer or the user of MT10 should assure that it is used
in such an environment.

MT10 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of
MT10 can help prevent electromagnetic interferences by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and MT10 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.
Guidance and Manufacturer's Declaration - Electromagnetic Immunity
MT10 is intended for use in the electromagnetic environment specified below. The customer or the user of MT10 should assure that it is used
in such an environment.

Electromagnetic environment - guidance
MT10 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.
MT10 is suitable for use in all commercial, industrial, business, and
residential environments.

material, the relative humidity should be
greater than 30%.
RF wireless communications equipment
should not be used close to any parts of
MT10.
Mains power quality should be that of a
typical commercial or residential environment.
