Guidance and manufacturer’s declaration – electromagnetic immunity
The Trinity ELE is intended for use in the electromagnetic environment specified
below. The customer or the user of the Trinity ELE should assure that it is used in
such an environment.

Portable and mobile RF communications
equipment should be used no closer to
any part of the Trinity ELE, including
cables, than the recommended separation
distance calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distance
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 metres (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 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 Trinity ELE is used exceeds the applicable RF
compliance level above, the Trinity ELE should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the Trinity ELE.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less
than [V1] V/m.
