Guidance and manufacture’s declaration – electromagnetic immunity
The ECG100G ECG is intended for use in the electromagnetic environment specified below. The customer or the user of
ECG100G ECG 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 ECG100G
ECG, 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 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 ECG100G ECG is used exceeds the applicable
RF compliance level above, the ECG100G ECG should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the ECG100G
ECG.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
