Portable and mobile RF communications
equipment should be used no closer to any
part of the T/Pump system, including cables,
than the recommended separation distance
calculated from the equation appropriate for
the frequency of the transmitter.
Recommended Separation Distance
d=1,2√P
d=1,2√P
80 MHz to 800 MHz
d=2,3√P
800 MHz to 2,5 GHz
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 (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
equipment marked with the following symbol:
Note:
At 80 MHz and 800 MHz, the higher frequency range applies.
Note:
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 T/Pump system is used exceeds the
applicable RF compliance level above, the T/Pump system should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the T/Pump
system.
b
Over the frequency range 150 kHz to 80 MHz, field strengths are less than 3 V/m.
Guidance and Manufacturer’s declaration - Electromagnetic Emissions
The T/Pump system is intended for use in an electromagnetic environment specified below. The customer or the user
of the T/Pump system should ensure that it is used in such an environment.
