Electromagnetic environment – guidance
Floors should be wood, concrete or ceramic tile. If floors 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.
Mains power quality should be that of a typical commercial or
hospital environment.
If the user of the HX camera heads requires continued operation
during power mains interruptions, it is recommended that the HX
camera heads be powered from an uninterruptible power supply
or a battery.
If image distortion occurs, it may be necessary to position the
HX camera heads further from sources of power frequency
magnetic fields or to install magnetic shielding. The power
frequency magnetic field should be measured in the intended
installation location to assure that it is sufficiently low.
