Electro-Magnetic Immunity
This EUT is intended for use in the electromagnetic environment specified below.
The customer or the user of the EUT should assure that it is used in such an environment.
Immunity Test

Mains power quality should be that of a
typical commercial or hospital environment.
If the user of the EUT image intensifier
requires continued operation during power
mains interruptions, it is recommended that
the EUT image intensifier be powered from
an uninterruptible power supply or a battery.
Power frequency

Power frequency magnetic fields should
be at levels characteristic of a typical
location in a typical commercial or hospital
environment.
NOTE
UT is THE A.C mains voltage prior to application of the test level.
