The quality of the supply
voltage should correspond to
that of a typical business or
hospital environment. If the
user of the device requires
continued FUNCTION, even
in the event of interruptions
to the power supply, it is
recommended that the
device be supplied from an
uninterruptible power supply
or a battery.

typical of those found in
business and hospital
environments.
GUIDELINES AND MANUFACTURER DECLARATION - ELECTROMAGNETIC
INTERFERENCE IMMUNITY
The device can be used in both static and mobile operation, in both domestic and
appropriate hospital environments.
In a domestic environment, the device may cause radio interference, possibly making it
necessary to take suitable remedial measures, such as realigning the device, for example.
