Electromagnetic Compatibility (EMC)
Guidance and Manufacturer’s Declaration—Electromagnetic Immunity
The ABPM devices are intended for use in the electromagnetic environment specified below. It is the responsibility of the
customer or user to ensure that the ABPM devices are used in such an environment.

Portable and mobile RF communications
equipment should be used no closer to any
part of the ABPM devices, including
cables, than the recommended separation
distance calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distance:
d = 1.17
√P
d = 1.17
√P
at 80 MHz to 800 MHz
d = 2.33
√P
at 800 MHz to 2.7 GHz
where
P
is the maximum output power rat-
ing of the transmitter in watts (W) accord-
ing to the transmitter manufacturer and
d
is the recommended separation distance in
meters (m).
Field strengths from fixed RF transmitters,
as determined by an electro-magnetic site
survey
a
, should be less than the compli-
ance level in each frequency range

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
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 ABPM devices are used exceeds the applicable RF compliance
level above, the ABPM devices should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the equipment.
b)
Over the frequency range from 150 kHz to 80 MHz, field strengths should be less than 3.0 V/m.
