Abstract

This invention concerns an indicating device on a printed circuit board or the like to indicate voltage drop-out in associated equipment, in particular telecommunication equipment, comprising a display unit mounted on the front of the printed circuit board. According to the invention a solar cell 7 is arranged on the front 4 next to the display unit 5 in order to take over the power supply to this in the event of a voltage drop-out, whereupon the display unit displays and identifies the type of fault. <IMAGE>
