Diagnosing the IED status via the LHMI hint menu

In order to help the user, there is an LHMI page labeled 'Hints'. This page is located under
Main menu/Diagnostics/IED status/Hints. For each activated hint there is a headline.
From the headline view, an explanation page can be entered, giving the user more
information and hints about the particular topic.
For example, if there is a configuration to use IEC 61850 9–2 analog data, but no data
arrives on the access point, then the IED will use substituted data and most protection
functions will be blocked. This condition will be indicated with a sub-menu under Hints,
where details about this condition are shown. The Hint menu is a way to assist the user in
troubleshooting.
The Hint menu is currently only available in English. All the entries are in
English, regardless of which language is selected.
The supported list of hints are as follows:

Explanation
There are two explanations possible:
SyncLostMode is set to Block , no time source is
configured to achieve the required accuracy. Unless
a high accuracy time source is selected, the function
dependent on high time accuracy will be blocked.
SyncLostMode is set to BlockOnLostUTC , but there
is no UTC capable synch source (GPS, IRIG-B)
used. Unless a UTC capable time source is selected,
the function dependent on high time accuracy will be
blocked.
