Guidance and manufacturer's declaration-electromagnetic immunity
The ET1519/1919LM is intended for use in the electromagnetic environment specified below. The user of the
ET1519/1919LM 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.

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 ET1519/1919LM is
used exceeds the applicable RF compliance level above, the ET1519/1919LM should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the ET1519/1919LM.
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 ET1519/1919LM, including cables, than the
recommended separation distance calculated from
the equation applicable to the frequency of the
transmitter.
Recommended separation distance
d=1.2 P
3 Vrms
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
