The quality of the line power supply
should be that of a typical commercial
or hospital environment.
If the user of the
UNIT
requires it to
continue functioning following
interruptions of the power supply, it is
recommended to have the
UNIT
powered by an uninterruptible power
supply or a battery.

power frequencies
(50/60 Hz) according
to
IEC 61000-4-8
3 A/m
3 A/m
Power frequency magnetic fields should
be at levels characteristic of a typical
location in a typical commercial or
hospital environment.
Remarks: U
T
is the AC supply voltage prior to application of the test level.
