Hardkeys
The right-hand side is reserved for operating elements,
the left-hand side for displays.
E
This key switches the system screen from standby
to measuring mode and vice versa.
The system screen mode depends on the
ventilator mode:
Standby can only be selected on the system
screen if the ventilator is also in standby.
The system screen starts up when the ventilator is
started.
G
This key is used to deactivate the alarm tone for
two minutes. It is reactivated by pressing the key
again. The yellow LED in the key lights up while
alarms are suppressed (see page 79).
During this period, any new advisory and caution
messages will not be audibly signalled but will
appear as text in the alarm fields. Only new
warnings will be signalled once by the appropriate
tone sequence.
Inside the dark area, there are four keys acting directly on
the screen contents:
S
This key is used to call up a menu of the available
display options on the system screen. Selection is
made by turning and pressing the rotary control
(see page 68).
Q
This key always calls up the last standard screen
used (see page 68).
s
This key is used to »freeze« the curves on the
display so that they can be viewed in more detail.
U
This key is used to generate a manual entry in the
list screen (see page 70).

G
key are two bar-shaped indicators that
indicate the alarm status even when the acoustic alarm
has been switched off.
