EID for Life-Support Functions

The life-support functions a of the E Series unit are intended for use in the electromagnetic environment specified
below. Ensure that the E Series unit is used in such an environment.
Immunity Test IEC 60601 Test Level
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to 80 MHz
outside ISM bands
10 Vrms
150 kHz to 80 MHz
in ISM bands
Radiated RF 10 V/m
IEC 61000-4-3 80 MHz to 2.5 GHz
NOTE 1 At 80 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.
The life-support functions on the E Series unit are pacing and defibrillation.
a
The ISM (industrial, scientific, and medical) bands between 150 KHz and 80 MHz are 6.765 MHz to 6.795 MHz;
b
13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz.
The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the frequency range
c
80 MHz to 2.5 GHz are intended to decrease the likelihood that mobile/portable communications equipment could
cause interference if it is inadvertently brought into patient areas. For this reason, an additional factor of 10/3 is used
in calculating the recommended separation distance for transmitters in these frequency ranges.
d 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 E Series unit is used exceeds the
applicable RF compliance level above, the E Series unit should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as reorienting or relocating the E Series unit.
e Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.

Electromagnetic Environment — Guidance
Portable and mobile RF communications equip-
ment should be used no closer to any part of the
E Series unit, including cables, than the recom-
mended separation distance calculated from the
equation applicable to the frequency of the trans-
mitter.

d = 2.3 800 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 recom-
mended separation distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
should be less than the compliance level in each
frequency range. e
