Madsen Zodiac User Manual page 49

MADSEN Zodiac isintended for use in the electromagnetic environment specified below. The user of MADSEN Zodiac should ensure that it isused in such an
environment.

Note 1
:At 80 MHzand 800 MHz the separation distancefor the higher frequency range applies.
Note 2
:These guidelinesmay not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and
people.
a. Field strengthsfrom fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios,amateur radio, AM and FMradio
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 beconsidered. If the measured field strength in the location in which MADSEN Zodiac isused exceeds the applicable RF
compliance level above, the MADSEN Zodiac should be observed to verify normal operation. If abnormal performance is observed, additional measures
might benecessary, such as reorienting or relocating MADSEN Zodiac.
b. Over the frequency range 150 kHzto 80MHz, field strengths should beless than 3 V/m.
Recommended separation distances between portable and mobile RF communications equipment and MADSEN Zodiac
The MADSEN Zodiac is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the
MADSEN Zodiac can help prevent electromagnetic interference by maintaining aminimum distance between portable and mobile RF communications equip-
ment (transmitters) and the MADSEN Zodiacas recommended below, according to the maximum output power of the communications equipment.

Electromagnetic environment - guidance
Portableand mobile RF communications equipment
should beused 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 80MHz to 800 MHz
d = 2.3 for 80MHz to 2.5 GHz,
