that of a typical commercial or
hospital environment. If the user
of
the recorder requires
continued operation during
power mains interruptions, it is
recommended that the recorder
be

3A/m 3A/m If image distortion occurs, it may
be necessary to position the
recorder 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 UT is the a.c. mains voltage prior to application of the test level.
