13.2 Indication on Failure of Restricted Functions
Usually, there is no indication of any error or warning if the execution of
functions is prohibited in case of restrictions, because the user immediately
notices whether the desired function is performed correctly. Nevertheless,
some warnings need to be indicated to the user as a feedback, e.g. if a
complete console dump fails because of a write-protected memory card.
The means to indicate to the user a failure during function execution is a
dialog box appearing always at the same position on the touch-screen. It
displays a system message and will disappear when the user acknowledges
the message by touching the “OK” field in the box.
Each of these system messages is also entered to the Log List. To be re-
moved from the Log List, it has to be acknowledged by the user.
To prevent from annoying the user with lots of warning and error message
dialog boxes, they are generated only where it is not possible to notice
function execution failure. In these cases an error message is generated if
the function execution fails completely. A warning is given to the user if a
function might be executed partially only.
Example: The snapshot recall function could not set all channels due to different
input channel types:
The user has to acknowledge the dialog box before any other action on the
touch-screen will be accepted. Touching configuration keys, e.g. SEL or
EQ, which would lead to a different page on the touch-screen, will also be
ignored as long as the dialog box has not been acknowledged.
