RE: 97S low battery Indicator with no display
Hello,

I think you can find some clues in

http://www.panamatik.de/Taschenrechnersammlung.pdf

from page 96 and forwards, in particular page 101. Some components are common for HP-19c and HP-97, in particular for the printer. The HP-19c has a less advanced printer which does not detect when out of paper and the head drive worm gear is unidirectional, so there are less components.

Best regards
Jonas
