Electromagnetic resistance to interference (IEC 60601-1-2, Table 202)
The ARC 250 and ARC 303 are intended to be used in the electromagnetic environment described below.
The customer or user of the ARC 250 and ARC 303 should ensure that these devices are operated in such an
environment.

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

The quality of the mains
power should correspond
to that of a typical business
or hospital environment.

The quality of the mains
power should correspond
to that of a typical business
or hospital environment. If
the user of the ARC 200,
ARC 250, ARC 300e and
ARC 303 requires it to
continue operating even in
the event of mains power
dropout, it is recommended
to use an uninterruptable
power source or battery to
supply power the ARC 250
and ARC 303.
Note: U
T
is the AC supply voltage prior to the application of the test level.
