Electromagnetic Immunity
The ABPM6100 is intended for use in the electromagnetic environment specified below. The customer or the user
of the ABPM6100 should assure that it is used in such an environment.

guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the ABPM6100, including cables,
than the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.

Field strengths from fixed RF transmitters,

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 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 ABPM6100 is used
exceeds the applicable RF compliance level above, the ABPM6100 should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the ABPM6100.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
