Description of sparepart
The resistors R30 and R40 are equipped with two 1MOhm resistors in parallel circuit. This configuration
results in an effective resistor of 500K.
If the board which has to be replaced is equipped with 1M resistors:
One of both R30 and R40 has to be removed by side cutting pliers.
