The supply voltage quality
must correspond to that of a
typical commercial or hospi-
tal environment. If the user of
the SONIDOSMART requires
continued functionality even
in the case of interruptions to
the power supply, it is rec-
ommended that the
SONIDOSMART be powered
from an uninterruptible power
supply or a battery.
Magnetic field at
the supply fre-
quency (50/60
Hz)
in accordance
with IEC 61000-
4-8 3 A/m 3 A/m Magnetic fields at mains fre-
quency should have the typical
values found in a commercial
or hospital environment.
