As described in annex A.
3 of IEC 60601-1-2, the
voltage induced on a
cable in the frequency
range 150 kHz to 80
MHz from a field strength
of 10 V/m is unlikely to
exceed 6 V r.m.s. There-
fore, assuming a field
strength E of 10 V/m in
the ISM and amateur
radio bands between
0.15 MHz and 80 MHz
(see note 2), the min-
imum separation dis-
tance d in m to a RF
communications equip-
ment with a maximum
power P in W can be cal-
culated using the equa-
tion in clause 8.10 of IEC
60601-1-2:
d = 6 / E ∙ √P

Mains power quality
must be that of a typical
commercial or hospital
environment. If the use
of the miha-bodytec II
EMS training device
requires continued ope-
ration during power
mains interruptions, an
uninterruptible power
supply (UPS) sufficiently
fast and powerful to pro-
vide the energy needed
must be used.
