Electromagnetic environment -
guidance
The Medical LED Headlight is intended for use in the electromagnetic environment specified
below. The customer or the user of The Medical LED Headlight should assure that it is used in
such an environment.
Floors should be wood, concrete or
ceramic tile. If floor are covered
with synthetic material, the relative
humidity should be at least 30%.
Mains power quality should be that
of a typical commercial or hospital
environment.
Mains power quality should be that
of a typical commercial or hospital
environment.
Mains power quality should be that
of a typical commercial or hospital
environment. If the user of The
Medical LED Headlight requires
continued operation during power
mains interruptions, it is
recommended that The Medical
LED Headlight be powered from an
uninterruptible power supply or a
battery.
Power frequency magnetic fields
should be at levels characteristic of a
typical location in a typical
commercial or hospital environment.
