5  Maintenance

5.2.6.2  Adjusting the sensitivity for oxygen

The sensitivity for oxygen is adjusted with fresh air.
1.  Make sure that only fresh air is being drawn in.
2.  Open 

Settings

.

3.  Select 

Adjustment

 menu item.

4.  Select 

Adjustment O2

 menu item.

5.  Wait until the displayed reading is stable. (The reading may 

still flash.)

6.  Select 

20.9 % VOL. (fresh air)

 from the menu (select and 

confirm  with 

OK

). This  adjusts  the  sensitivity. The  reading 

shows 20.9 % vol.

5.3 

Servicing

The device must only be serviced and repaired by SEWERIN 

Service.

 

●

Send the device to SEWERIN for repairs and for annual main-

tenance.

Note:

If there is a service agreement in place, the device can be ser-

viced by the mobile maintenance service.

The inspection plate on the device shows con-

firmation  of  the  last  maintenance  and  the  next 

scheduled maintenance.
