Floors should be of wood, concrete or
ceramic tile. If the floor is of synthetic mate-
rial, the relative humidity must 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 Leica M525 OH4 surgical
microscope requires that the instrument
remain functional even after mains power
interruptions, it is recommended that the
Leica M525 OH4 surgical microscope be
provided with an auxiliary power source
such as an uninterruptible power supply
(UPS) or battery back-up.
