portable and mobile RF communications equipment and the MA 28.
The MA 28 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or
the user of the MA 28 can help prevent electromagnetic interferences by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the MA 28 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.

Operation Manual MA 28
Electromagnetic environment - guidance
The MA 28 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 MA 28 is suitable for use in all commercial, industrial, business,
and residential environments.
