Floors should be made of
wood or concrete or be
fitted with ceramic tiles.
If the floor is fitted with
synthetic material, the
relative humidity must
be at least 30%.

The quality of the supply
voltage should corres-
pond to that of a typical
business or hospital en-
vironment. If the user
needs the DIAGNOcam
2170 U to work even if
the power supply is in-
terrupted, we recom-
mend supplying energy
to the DIAGNOcam 2170
U from an uninterrupt-
ible power supply or bat-
tery.
Magnetic field at a sup-
ply frequency (50/60 Hz)
according to EN
61000-4-8
3 A/m
3 A/m
Magnetic fields at the
mains frequency should
correspond to typical
values in a business and
hospital environment.
Note: U
T
is the alternating mains voltage before the test level is used.
9.3 Immunity to electromagnetic interference
The DIAGNOcam 2170 U is designed for use in an environment of the kind spe-
cified below. The customer or the user of the DIAGNOcam 2170 U should en-
sure that the device is used in an environment of the specified type.
