About 2.5 seconds after starting the
engine, if faults are present, the system
warnings start popping-up. The red pop-
ups appear first, followed by the yellow
popups. With the pop-up screens the
‘general warning’ indicators and an
acoustic signal are activated.
After all the pop-ups have been displayed,
the master display automatically switches
to the warning list in the service info menu.
If there are red as well as yellow pop-ups,
a red hazard warning triangle is displayed
in the top right-hand corner of the master
display.
NOTE
When there are more warnings than fit
the display, this is indicated by arrows
on the right side of the display. The
warnings are displayed in order of pri-
ority. This means the most important
warning is displayed first.
Turning the Menu Control Switch (MCS)
brings up the hidden ones, An arrow
with a line attached to it indicated the
beginning or end of the list.
NOTE
A red warning cannot be removed
from the screen when the engines is
running.
The red warning can be suppressed by
pressing the Menu Control Switch when
the engine is not running. This allows
selection of other menu options.
The Warning always reappears after re-
turning to the main screen.
A continuous acoustic signal accompa-
nies a red warning.
NOTE
Yellow warning can be suppressed at
any time.
A pulsating acoustic signal accompanies
a yellow warning and sounds four times.
The red hazard warning triangle in the top
right hand corner of the master display
remains active at all times.
NOTE
If the safety belt or safety belts are not
fastened after the engines has been
started, the red warning indicator “Seat
belt” comes on for 6 seconds and then
disappears.
