Not applicable The quality of the supply
voltage should correspond
to that of a typical business
or hospital environment.
If the user of the model
DX6635 wants continuous
function even in case of
interruptions of the energy
supply, we recommend
supplying the model DX6635
with an uninterruptable
power supply or a battery.
