7.6.3 Electromagnetic immunity (IEC 60601-1-2 Table 203)
The AED7000 is intended for use in the electromagnetic environment specified below. The customer
or the user of the AED7000 should ensure that it is used in such an environment.

a. The ISM (industrial, scientific, and medical) bands between 150 kHz and 80 MHz are 6.765 MHz
to6.795 MHz; 13.553 MHz to 13.567 MHz; 26.957 MHz to 27.283 MHz; and 40.66 MHz to 40.70 MHz.
b. The compliance levels in the ISM frequency bands between 150 kHz and 80 MHz and in the
frequency range 80 MHz to 2.5 GHz are intended to decrease the likelihood that mobile or 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.
c. Field strengths from fixed transmitters, such as base stations for radio (cellular or cordless) telepho-
nes and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be

Portable and mobile RF communications
equipment should be used no closer
to any part of the AED7000, inclu-
ding cables, than the recommended
separation distance calculated from the
equation applicable to the frequency of
the transmitter.
Recommended separation distance :

Where P is the maximum output power
rating of the transmitter in watts (W)
and d is the recommended separation
distance in meters (m). b
Field strengths from fixed RF transmit-
ters, as determined by an electroma-
