The quality of the supply
voltage should be that of a
typical business or hospital
environment. If the user of
EXTARO 300 requires
continued function even in the
event of interruptions in the
power supply, we recommend
to power the device EXTARO
300 from an uninterruptible
power supply or a battery.
