Press the »OK« key to initiate the final storage of all parameter changes. Confirm the parameter changes by pressing
the »Yes« softkey or dismiss by pressing Softkey »No«.
In addition to the star trace to the temporary saved parameter changes, a
general parameter changing symbol is faded-in at the left corner of the display,
and so it is possible from each point of the menu tree to see that there are
parameter changes still not adopted by the device.
If the display shows a Key Symbol instead of a Wrench-Symbol, this will
indicate, that the required access authorization is not available.
In order to edit this parameter, a password is required, that provides the
required authorization.
Plausibility check: In order to prevent obvious wrong settings the device
monitors constantly all temporary saved parameter changes. If the device
detects an implausibility, this is indicated by a question mark in front of the
respective parameter.
In order to make things easier to follow up, especially where complex
parameter changes are involved, on every superior/higher-ranking menu level,
above the temporarily saved parameters an invalidity is indicated by the
question mark (plausibility trace). This makes it possible to control or follow
from the main menu level at any time where implausibilities are intended to be
saved.
In addition to the question mark trace to the temporary saved implausible
parameter changes a general implausibility symbol/question mark is faded-in at
the left corner of the display, and so it is possible to see from each point of the
menu tree that implausibilities have been detected by the device.
A star/parameter change indication is always overwritten by the question
mark/implausibility symbol.
If a device detects an implausibility, it rejects saving and adopting of the
parameters.
