Mains power quality should be that of a typical com-
mercial or hospital environment. If the user of the
MADSEN Zodiac requires continued operation during
power mains interruptions, it is recommended that the
MADSEN Zodiac be powered from an uninterruptible
power supply or a battery.

Guidance and manufacturer's declaration - electromagnetic immunity - for equipment and systems that are NOT life-supporting
MADSEN Zodiac is intended for use in the electromagnetic environment specified below. The user of MADSEN Zodiac should ensure that it is used in such an
environment.

Portable and mobile RF communications equipment
should be used no closer to any part of MADSEN Zodiac,
including cables, than the recommended separation dis-
tance calculated from the equation applicable to the fre-
quency of the transmitter.
Recommended separation distance:
d = 1.2
d = 1.2
for 80 MHz to 800 MHz
d = 2.3
for 80 MHz to 2.5 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 dis-
tance in metres (m).
Field strengths from fixed RF transmitters, as determ-
ined by an electromagnetic site survey,

should be less
than the compliance level in each frequency range.
