Mains power quality should
be
that of a typical
commercial or hospital
environment. If the user of
the
Aoralscan 2 requires
continued operation during
power mains interruptions,
it is recommended that the
Aoralscan 2 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.
If image distortion occurs, it
may be necessary to
position the
Aoralscan 2
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.

For example, 10/12 means 10 cycles at 50 Hz or 12 cycles at 60 Hz.
