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

Portable and mobile RF communications equip-
ment should be used no closer to any part of
MADSEN AccuScreen, including cables, than the
recommended separation distance calculated from
the equation applicable to the frequency 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 trans-
mitter manufacturer and d is the recommended
separation distance in metres (m).
Field strengths 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 equip-
ment marked with this symbol:
Note 1: At 80 MHz and 800 MHz the separation distance for the higher frequency range applies.
Note 2: These guidelines may not apply in 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 MADSEN AccuScreen is used exceeds the applicable
RF compliance level above, the MADSEN AccuScreen should be observed to verify normal operation. If abnormal performance is observed, additional meas-
ures might be necessary, such as reorienting or relocating MADSEN AccuScreen.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
