marks in the top field of the screen, see page 54.
Caution and Advisory level messages are not transmitted. The
nurse call is activated also when the internal loudspeaker in
the ventilator is faulty.

The central hospital alarm system may only be connected
to the nurse call if Evita 2 dura is connected to the mains
power supply via a mains power cable or if it has been
earthed via the earth connection on the back of the unit.
Electric power may pose a hazard in all other cases.
Only alarm messages of the highest priority
(see page 54) are transmitted via nurse call.
Connection of a nurse call does not relieve staff of their
duty to check the monitoring on the Evita 2 dura screen
at regular intervals.
● Screen displays must be checked regularly.
A fault in any of the components in the link between
nurse call and central hospital alarm system (e.g. in
the electronics for nurse call in Evita 2 dura, in the
Evita 2 dura power supply or in the alarm generator of the
central hospital alarm system) may result in failure of the
nurse call.
