12.2 Maintenance reminder
The service symbol flashes in the start screen to indicate one
of the following conditions:
• Maintenance interval has expired
• Interval for device Technical Safety Check
(„Sicherheitstechnische Kontrolle“ in accordance with § 11 of
the German regulation MPBetreibV) has expired
• Battery life has expired
If maintenance or a Technical Safety Check („Sicherheitstechnische
Kontrolle“ in accordance with § 11 of the German regulation
MPBetreibV) is due, you can suppress the maintenance reminder
once within a maintenance cycle for a maximum of 180 days from
the due date. The device then behaves as if it were not due for
maintenance.
Suppression of the maintenance reminder cannot be canceled
within the maintenance cycle. Once the 180 days have elapsed,
the maintenance reminder is active until the next service, and
cannot be deactivated again.
Maintenance intervals must be observed even if the maintenance
reminder has been suppressed.
Disrupted or failed therapy due to lack of maintenance!
The maintenance reminder can be suppressed by the operator
once for 180 days. No maintenance notices will be displayed
during this period. If maintenance intervals are not observed,
malfunctions might occur. This can cause serious or life-
threatening injury to the patient.
Observe the maintenance intervals in accordance with the
instructions for use.
