Hi Marc,
try a cleaning with printed board solder flux cleaner like
Electrolube "Flux Clean" or contact cleaner like Chemitronics "Pow-R-Wash" without warranty.
Fortunatly, if it's ok afeter cleaning, protect the contacts with Electrolube "contact Grease" and remove all Nicad battery when calculator is not used
Regards.
Philippe
