Guidance and manufacturer’s declaration – electromagnetic immunity
The
A.T.S.
3000 is intended for use in the electromagnetic environments specified below. The customer or the user of the
A.T.S.
3000 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 A.T.S. 3000, 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 levels 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) telephone 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
A.T.S.
3000 is used exceeds the application RF compliance levels
above, the
A.T.S.
3000 should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as re-orienting or relocating the
A.T.S.
3000.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
