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.

3 A/m 3 A/m Power frequency magnetic fields should be at levels
characteristic of a typical location in a typical
commercial or hospital environment.
NOTE: Uт is the a.c. mains voltage prior to application of the test level.
