The power supply quality
should be that of a typical
commercial or hospital
environment. If the user
of the product requires
continued operation in
the event of interruptions
to the power supply net-
work, it is recommended
that the product be oper-
ated with an uninterrupt-
ible power supply or a
battery.
Magnetic field at
the power fre-
quency (50/60 Hz)
acc. to IEC
61000-4-8
30 A/m at 50 Hz / 60 Hz
30 A/m at 50 Hz / 60 Hz
If image distortion occurs,
it may be necessary to in-
stall the product further
from sources of electro-
magnetic fields or to in-
stall magnetic shielding.
Before the product is in-
stalled, the electromag-
netic field should be mea-
sured to ensure that it is
sufficiently low.
