Compliance Level
Risk assessment on the CEFAR EASY
Electrotherapy System indicates
±6kV contact
the compliance levels claimed are
±8kV air
acceptable when ESD-precautionary
measures are taken.
Not Applicable -
Battery powered
Mains power quality should be that
of a typical commercial or hospital
Not Applicable
environment.
- signal lines less
then 3 meters
Mains power quality should be that
Not Applicable -
of a typical commercial or hospital
Battery powered
environment.
Mains power quality should be that
of a typical commercial or hospital
environment. If the user of the
CEFAR EASY Electrotherapy System
Not Applicable -
requires continued operation during
Battery powered
power mains interruptions, it is
recommended that the CEFAR EASY
Electrotherapy System be powered
from an uninterrupted power supply.
3 A/m
Power frequency magnetic fields
should be at levels characteristic
of a typical location in a typical
commercial or hospital environment.
