If the user of the KaWe examination lamp
requires continued operation during
power interruptions, it is recommended
that the KaWe examination lamp be
powered from an uninterruptable power
supply or a battery.

frequency of (50/60 Hz)
according to IEC 61000-4-8
3 A/m
30 A/m
Magnetic fields with their line
frequencies should be the same as those
typical of commercial and hospital
environments.
Note
: U
