NOTE 1: At 80 MHz and 800MHz, 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 the
Eclipse Premier is used exceeds the applicable RF compliance level above, then the Eclipse Premier should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the Eclipse Premier.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
c
Amplitude modulated at 80% with a modulation frequency of 10 KHz per EN 60601-2-25.

guidance
Portable and mobile RF communications
equipment should be used no closer to any part
of the Eclipse Premier, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency of
the transmitter.
Recommended separation distance
d = 1.2 √ P
d = 1.2 √ P
c
d = 2.3 √ P
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 metres
(m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
should be less than the compliance level in each
frequency range.
Interference may occur in the vicinity of
equipment marked with the following symbol:
80 MHz to 800 MHz
