HP-67 - JurgenRo - 01-21-2017 11:38 PM

Hi!
I have an HP-67 and noticed the other day that a tiny LED right under the Display, above the "R" of the "RUN" imprint is flickering when I try to feed a Card through the Card Reader. Couldn't find any documentation in the Manual. Does anyone know what this LED is indicating?

Thanks! Juergen

That's the low battery LED indicator.
Charge the battery pack.
