EMC Information
Electromagnetic environment
- guidance
Floors should be wood, concrete
or ceramic tile. If floor are
covered with synthetic material,
the relative humidity should be at
least 30%.
Mains power quality should be
that of a typical commercial or
hospital environment.
Mains power quality should be
that of a typical commercial or
hospital environment.
Power frequency magnetic fields
should be at levels characteristic
of a typical location in a typical
commercial or hospital
environment.
Mains power quality should be
that of a typical commercial or
hospital environment. If the user
of the system requires continued
operation during power mains
interruptions, it is recommended
that the system be powered from
an uninterruptible power supply
or a battery.
