Guidance and manufacturer's declaration-electromagnetic immunity
The ET2400LM is intended for use in the electromagnetic environment specified below. The user of the ET2400LM
should assure that it is used in such an environment.
Immunity test IEC 60601 test level
Conducted RF 3 Vrms
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz to 2.5 GHz
NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 2 These guidelines may not apply in all situation. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
3. Filed 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 filed strength in the location in which the ET2400LM is used exceeds the
applicable RF compliance level above, the ET2400LM should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the ET2400LM.
4. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 Vrms.
Compliance Electromagnetic environment-guidelines
level
Portable and mobile RF communications equipment
should be used no closer to any part of the
ET2400LM, including cables, than the recommended
separationdistance calculated from the equation ap
plicable to the frequency of the transmitter.
Recommended separation distance
3 Vrms d=1.2 P
3 Vrms d=1.2 P 80MHz to 800 MHz
d=2.3 P 800 NHz to 2.5GHz
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)
Filed strengths from fixed RF transmitters, as
determined by an electromagnetic site survey
should be less than the compliance level in each
frequency range
