Electromagnetic Immunity – Part 2
The Activator is intended for use in the electromagnetic environment
specified below. The customer or the user of the Activator should assure
that it is used in such an environment.

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,' 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.
Electromagnetic environment-guidance:
Portable and mobile RF communications equipment should be used no closer to any
part of the Activator, including cables, than the recommended separation distance calculated from the equation applicable to
the frequency of the transmitter.
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 Activator is used exceeds the applicable RF compliance level above, the Activator
should be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary,
such as re-orienting or relocating the Activator.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
