Guidance and Manufacturer’s Declaration - Electromagnetic Immunity
The MAICO MA 42 is intended for use in the electromagnetic environment specified below. The customer or
the user of the MA 42 should assure that it is used in such an environment.

of the MA 42, including cables than the
recommended separation distance calculated
from 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 and
d is the
recommended separation distance in meters (m).
Field Strengthens from fixed RF transmitters, as
determined by an electromagnetic site survey
(a*), should be less than the compliance level in
each frequency range (b*).
Interference may occur in the vicinity of
equipment marked:
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.
(a*) Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones
and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted
theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an
electromagnetic site survey should be considered. If the measured field strength in the location in which
the MA 42 is used exceeds the applicable RF compliance level above, the MA 42 should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as re-orienting or relocating the MA 42.
(b*) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
