Guidance and Manufacturer's Declaration - Electromagnetic Immunity
The Propulse is intended for the use in the electromagnetic environment specified below.
The customer or the user of the Propulse should assure that it is used in such an environment

NOTE 1: At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflections 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 Propulse is used exceeds the applicable RF compliance level
above, the Propulse should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the Propulse.
b.
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended Separation Distance between portable and mobile
The Propulse is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the Propulse can help prevent
electromagnetic interference by maintaining minimum distance between portable and mobile RF
communications equipment (transmitters) and the Propulse as recommended below, acco rding to
the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation
distance d in meters (m) can be estimated using the equation applicable to the frequency of the
transmitter, where p is the maximum output power rating of the transmitter in watt (W) according
to the transmitter manufacturer.
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

Electromagnetic environment – guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the Propulse, including cables, than
the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter:
Recommended protection distance:
d = 1.17 vP
d = 1.17 vP for 80 MHz to 800 MHz
d = 2,3 vP for 800 MHz to 2.5 GHz
where P is the maximum output power rating
of the transmitter in watts (W) acc. To the
transmitter manufacturer and d is the
recommended separation distance in meters
(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.
