Hi,
I had need of my Systron Donner 6520 counter today and when I turned it on the display flashed on for an instant and then went out. No actions would make it operate. I did notice if I left it off for 20 minutes and tried again the same thing happens. Hopefully a power supply issue. I can't find any leads to a manual (with schematics). Can any one help?
Cheers!
Corby
