Exchange of the upper part
It is possible to exchange the upper part only:
1)
Open the calculator and disconnect the plug of the power supply. However, the screw terminals
need not be unscrewed.
2)
Carefully disconnect the plug of the ribbon cable from the upper part.
3)
Now the upper part is separated from the lower part. The hinge can be clipped off if the upper part is
widely open >180°. Best hold both parts at their tops and press the upper part backwards.
4)
The assembling is done the other way round.
Attention: only connect or disconnect the ribbon cable if there is zero voltage in the
calculator.
