Mains power quality should be that of a
typical commercial or hospital
environment. If the user of the VSM 300
Series monitor requires continued
operation during power mains
interruption, it is recommended that the
monitor be powered from an
uninterruptible power supply or a battery.
Power frequency (50/60
Hz) magnetic field
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.
