I have my original Constellation 2Mhz and when I use my universal 9V 1000mA
adapter as I used to, the c6 field is blinking. A reset does not work , the rightmost controlboard functions to not respond only pushing a sensorfield results in another beep. If I use 6x 1,5 babycell batteries, all the leds blink (horizontal & vertical) but I think running on batteries is an very old problem.

I tried to open the device , remove the 4 gummy naps & screws that unveal themselves hereafter , as well the screw in the middle, still it won't open. I tried to remove the sides but something is withholding. Anyone familiar with opening a Conny/Superconny ?
I suppose one sensor (the c6) which is blinking is stuck or something alike.


Q1 how to open ?
Q2 what to spot for in such a case ?

Thanks in advance for any help. You may answer in German of course.
