How do I find the date of the next Maintenance?

You have a time window from 6 months before up to 6 months after the maintenance date. Choose one of the following methods to find the maintenance date:

Method 1:

As soon as the unit enters the time frame for a possible maintenance, it automatically displays the next maintenance date after switch on with the “next maint. in” message.

Method 2:

To view the next maintenance date (and other unit information), switch on the unit and press the button immediately when the “0” appears at the end of the switch-on procedure. Hold the button pressed until “next maint. in” is shown.

Method 3:

Refer to the unit’s Test Certificate.

Method 4:

Use the unit’s manufacturer date (mfd / DOM) and calculate the maintenance window with the according schedule. The unit’s (mfd / DOM) is located on the Test Certificate and on the serial label on the processing unit.
