Compliance level Electromagnetic environment—guidance
±6 kV contact Floors should be wood, concrete or ceramic tile. If
±8 kV air floors are covered with synthetic material, the
relative humidity should be at least 30%.
±2 kV Mains power quality should be that of a typical
commercial or hospital environment.
±1 kV
±1 kV differential Mains power quality should be that of a typical
mode commercial or hospital environment.
±2 kV common mode
<12V (>95% dip in Mains power quality should be that of a typical
240V) for 0.5 cycle commercial or hospital environment.
96V (60% dip in 240V) If the user of the device requires continued
for 5 cycles operation during power mains interruptions, it is
recommended that the device be powered from an
168V (30% dip in
uninterruptible power source.
240V) for 25 cycles
The internal battery will provide backup power of

characteristic of a typical location in a typical
commercial or hospital environment.

150 kHz to 80 MHz should be used no closer to any part of the device,
including cables, than the recommended separation
distance calculated from the equation applicable to
the frequency of the transmitter.
10 V/m Recommended separation distance
80 MHz to 2.5 GHz
d = 1.17 √P
d = 0.35 √P 80 MHz to 800 MHz
d = 0.70 √P 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 recommended
separation distance in meters (m). Field strengths
from fixed RF transmitters, as determined by an
electromagnetic site survey, a should be less than
the compliance level in each frequency range. b
