5.1. Parameter lock
The parameter lock is an additional function to protect the device from acci-
dental changes. Contrary to the password protection every user who has access
to the device can enable or disable the parameter lock.
The parameter lock can be activated in the security menu. From the moment the
parameter lock is activated no further settings can be made. All menus can still
be accessed in a read-only mode. When trying to change settings while the pa-
rameter lock is enabled the symbol for parameter lock will be shown on the dis-
play to remind the user that the mode is still enabled:
