EMC GUIDANCE AND DECLARATION - EM EMISSIONS/RF
Guidance and manufacturer’s declaration – electromagnetic immunity.
The
A.T.S.
4000TS is intended for use in the electromagnetic environments specifi ed below. The customer or the user of the
A.T.S.
4000TS
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.
4000TS, including cables, than the
recommended separation distance calculated from the equation applicable
to the frequency of the transmitter.

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 fi xed RF transmitters, as determined by an electro-
magnetic site survey

Interference may occur in the vicinity of equipment marked with the
following symbol:
Radiated RF IEC

3 V/m
80 MHz to 2.5 GHz
3 V/m
NOTES:
•
At 80 MHz and 800 MHz, the higher frequency range applies.
•
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and refl ection from structures,
objects and people.
a
Field strengths from fi xed 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 fi xed RF transmitters, an electromagnetic site survey should be considered. If the measured fi eld strength in the location in which
the
A.T.S.
4000TS is used exceeds the application RF compliance levels above, the
A.T.S.
4000TS 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.
4000TS.
b
Over the frequency range 150 kHz to 80 MHz, fi eld strengths should be less than 3 V/m.
