Changing the O-rings on the adapters
Frequency: every 3 months or every 600 cycles (whichever comes first).
Some adapters have internal O-rings that must be replaced by your
service technician during servicing.
See "Consumables, spare parts, and tools [ → 245]" for an overview of
which adapters require O-rings.
✔ The STANDARD lid is at hand.
1. Remove the O-rings from the adapters using a dental probe or other
instrument.
2. Slide the O-rings to the notches on the adapter.

Biennial Service
Frequency: every 2nd year or every 3000 cycles (whichever comes first).
When 2 years has passed or 3000 cycles, since the last service or the
DAC UNIVERSAL was put into use for the first time, the screen "Service
needed" will be displayed, simultaneously with a 2 second acoustic alarm.
When this happens a qualified technician must perform service on the
DAC UNIVERSAL, in order to ensure the performance of the DAC
UNIVERSAL.
WARNING
If the O-rings are not moved correctly to the notches on the adapter, the
instruments and the O-rings can be damaged. Correct sterilization is not
ensured.
