Any status or alarm messages (either WARNING or SOFT FAULT) appear on yellow background and are
flashing frequently in order to attract the operator's attention (see Figure 4-1 | Appearance of an alarm
message). In cases where more than one messages need to be displayed at the same time, they are being
automatically toggled every few seconds.
The WARNING messages appear only temporarily (for about three seconds), afterwards the indication is
restored automatically (see Section 4.3.a) First protection level - WARNING).
The SOFT FAULT messages appear in the same field but they remain on the screen until the AUTO OPERATE
time is elapsed (see Section 4.1.c) AUTO OPERATE user settings) or until the operator pushes any button.
k) Call sign area
Please, see Figure 3-2 | Basic screen, Pos. (k).
As its name suggests this field can be used to display the User's callsign, however, any custom text can be
set in the USER PREFERENCES menu.
