10.3 System initialization
In very rare instances, it could happen that a faulty file system (e.g.
because of a program crash) will lead to an impairment of program func-
tioning. The internal file system needs to be initialized in such cases.
Caution
All user data (methods, solutions, etc.) are deleted if a system initializa-
tion is carried out. Afterwards, the instrument will have the factory set-
tings again.
We recommend creating a backup copy of the system at regular inter-
vals in order to avoid data losses.
After a system initialization the program versions and language files do
not have to be reloaded. Only the selection of the dialog language may
have to be reset in the system settings.
