ELECTROMAGNETIC ENVIRONMENT - GUIDANCE
The MRIaudio Sound System uses RF energy only for its internal
function . Therefore, its RF emissions are very low and are not likely to
cause any interference in nearby electronic equipment .
The MRIaudio Sound System is suitable for use in all establishments
other than domestic and those directly connected to the public
low-voltage power supply network that supplies buildings used for
domestic purposes .
ELECTROMAGNETIC ENVIRONMENT - GUIDANCE
Floors should be wood, concrete or ceramic tile .
If floors are covered with synthetic material, the
±15 kV air
relative humidity should be at least 30% .
Main power quality should be that of a typical
commercial or hospital environment . If the operator
requires continued operation during power
interruptions, it is recommended that the system be
powered from an uninterrupted power supply or a
@ 0°
battery .
Power frequency magnetic fields should be at levels
30 A/m
characteristic of a typical location in a typical
commercial or hospital environment .
