Guidance and manufacturer’s declaration – electromagnetic immunity
The
Hummingbird ICP Control Module
is intended for use in the electromagnetic environment
specified below. The customer or the user of the
Hummingbird ICP Control Module
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
Hummingbird ICP Control
Module
, including cables, than the
recommended separation distance calculated
from the equation applicable to the frequency
of the transmitter.

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 1. At 30 MHz and 300 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 Hummingbird ICP Control Module is
used exceeds the applicable RF compliance level above, the Hummingbird ICP Control Module
should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the Hummingbird ICP Control
Module.
b
Over the frequency range 150 kHz to 30 MHz, field strengths should be less than 3 V/m.
