Replacing the EEPROM
Read the following information before replacing the EEPROM:
Do not replace the EEPROM and the RTC on the Control PCB at the same time.
Otherwise the recorded operating hours will be lost. If you need to replace both
components, do it in sequence, that is, complete the replacement of one
component first before starting the next one.
Existing software options, for example, "BIPAP" and "Autoflow" will be lost and
need to be reactivated again. You need to request the required release codes (see
also the following description).
Replace the EEPROM only with a brand-new EEPROM that has not been in use
before.
The unit must be off when replacing the EEPROM, and the battery fuse (fuse on
rear panel of the unit) must be removed.
Ensure the correct polarity. If the polarity of the EEPROM is reversed the EEPROM
will be destroyed. Remember the installation position of the EEPROM.
