Mains power quality should
be that of a typical
commercial or hospital
environment. If the user of
the
Aoralscan 3
requires
continued operation during
power mains interruptions, it
is recommended that the
Aoralscan 3
be powered
from an uninterruptible
power supply or a battery.

30 A/m
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 3
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.
NOTE:
U
T
is the a.c. mains voltage prior to application of the test level.
