The quality of the supply
voltage should correspond
to that in typical business or

user of the iMRS requires
uninterrupted functioning,
even when interruptions
in the power supply occur,
it is recommended to feed
the iMRS from an uninter-
ruptable power supply or a
battery.
Magnetic fields at mains fre-
quency should correspond to
values typical of a business
or hospital environment.
