Electromagnetic Compatibility (EMC)
Portable and mobile RF communications equipment can affect the MA 25/MA27. Install and operate the MA 25/MA27 according to the
EMC information presented in this chapter.
The MA 25/MA27 has been tested for EMC emissions and immunity as a standalone MA 25/MA27. Do not use the MA 25/MA27 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 MAICO 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 MA 25/MA 27 is intended for use in the electromagnetic environment specified below. The customer or the user of the MA 25/MA
27 should assure that it is used in such an environment.

Group 1
The MA 25/MA 27 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 between
portable and mobile RF communications equipment and the MA 25/MA 27.
The MA 25/MA 27 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the MA 25/MA 27 can help prevent electromagnetic interferences by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the MA 25/MA 27 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.
