CHAPTER 6

DEVICE OPERATION

This chapter decribes the device operation in more detail.

KEY LOCK

The key lock function is designed to protect against the accidental changing of
device settings. It deactivates all control functions, except:

• ON/OFF key to start ventilation

• ON/OFF key + MFK to stop the ventilation

• Alarm key

LOCK/UNLOCK KEYS

1. Press the Safe key.

Flashes on the toolbar for about 5 s.

2. Press the MFK during that time.

USER PROFILES

The device can operated in 2 different

profile

s - Clinic and Home. The user has

access to all device settings in the clinic mode. In contrast, the ventilation and
alarm parameters cannot be set up in the home mode.

The currently active user profile displays in the toolbar.
