HP-97 troubleshooting
Hi,

Some general questions about HP-97 troubleshooting.

My newly restored and cleaned HP-97 shows only the low battery light when switched on. The battery is not actually low, and besides the same thing happens when I connect the charger. What would you check?

Is it safe to operate the HP-97 with the printer unit and the card reader unit not connected or removed?

The card reader is located in a such a position that it is impossible to measure anything of fine-tune it. Is it possible to have the card reader unit connected from outside the calculator? Can it still work correctly if you connect it with a long flat cable (let's say about 20 cm)?

Thanks very much for any help!

Kees.
