Electromagnetic environment – guidance
Floors should be wood, concrete or ceramic
tile. If floors are covered with synthetic materi-
al, 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.
Mains power quality should be that of a typical
commercial or hospital environment. If the user
of EM34 requires continued operation during
power mains interruptions, it is recommended
that EM34 is be powered from an uninterrupti-
ble power supply or a battery.
Power frequency magnetic fields should be at
levels characteristic of a typical location in a
typical commercial or hospital environment.
