The quality of the voltage supply
should correspond to that of a
typical commercial or clinical
environment.
If the user wants the device to
work continuously, even when
the energy supply is interrupted,
it is recommended to use an
energy supply free of
interruptions or a battery.

Magnetic field at the network
frequency should correspond to
the typical values as they are in
a commercial and clinical
environment.
