Display device

摘要

In the display system disclosed, a manually operated switching arrangement sets a display circuit, which displays data in response to a data signal from a data circuit, either into a display mode or a non-display mode. A control arrangement controls the display of the display circuit independently of the switching arrangement and produces a display signal automatically when a display operation is necessary. A warning circuit sets the display circuit into the display state independent of the switching means for displaying warning data instead of display data.
