Hallo Schachfreunde,

ein amerikanischer Schachfreund hat folgendes gefragt bezüglich des von mir erhaltenen Polgar Modulsets:

"Under the key frame there is a battery wrapped in black tape. It seems to be attached to the circuit board with one wire and a second wire from the battery is not attached to the circuit board. There is second piece of black tape next to the small battery.

What does the battery do? It must not be working since the second wire from the battery is not connected to the circuit board. Is this a good battery? How should it be re-attached? Why is it wrapped in black tape?"

Ich habe keine Ahnung. Hat jemand einen Tipp was dies sein kann?

Dane im Voraus
Roberts
