Guidance and manufacturer’s declaration – electromagnetic immunity
The MAXI S 4000 Examination Chair is intended for use in the electromagnetic environment specified below.
The customer or the user of the MAXI S 4000 Examination Chair should assure that it is used in such an
environment.
Immunity Test

Portable and mobile RF communication
equipment should be used no closer to
any part of the MAXI S 4000 Examination
Chair, including cables, than the recom-
mended separation distance calculated
from the equation applicable to the fre-
quency of the transmitter.
Recommended separation distance
d = 1.2√P
d = 1.2√P 80 MHz to 800 MHz
d = 2.3√P 800 MHz to 2.3 GHz
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 strengths from fixed RF transmitters,
as determined by an electromagnetic sit
survey,a should be less than the
compliance level in each frequency
range.b
Interference may occur in the vicinity of
equipment marked with the following
