If by accident the display has been set too bright or too dark so that it can not be read off, this
may be changed as follows:
Switch off the ELD500 and turn it on again. During the run-up phase press the key no. 3 or 7

after confirming this through the contrast menu. If this setting is not confirmed, the former
setting will be applied after switching on the instrument on again.
