Yes, VR1 is the +5V setting and i have already set it back to +5V. I
don´t know if it is actually the program number that is shown but the
left display sais "1.8". There are no visible signs of corrosion but
it seems someone in the past had to repair to traces by soldering a
thin wire on the board. It´s still the model wihout any backup
battery.
