Mains power quality should be that of a
typical commercial or hospital
environment, If the user of the PF
LIGHT Image Intensifier requires
continued operation during power mains
Interruptions, It is recommended that
the PF LIGHT Image Intensifier be
powered from an uninterruptible power
supply or a battery.

If Image distortion occurs, It may be
necessary to position the PF LIGHT
Image Intensifier further from sources of
power frequency magnetic fields or to
install magnetic shielding. The power
frequency magnetic field should be
measured In the intended installation
location to assure that It is sufficiently
low.
