Guidance and Manufacturer’s Declaration - Electromagnetic Immunity - For Equipment and
Systems that are Not Life-Supporting
Portable and mobile RF communications equipment
should be used no closer to any part of the Maxi Sky
1000
,
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.
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 equipment marked
with the following symbol:
NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: Theses guidelines may not apply in all situations. Electromagnetic propagation if 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 Maxi Sky
1000
is used exceeds the applicable RF
compliance level above, the Maxi Sky
1000
should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the Maxi Sky
1000
.
(b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
