V
Rs: If the voltage of the signal line does not
change between 3.3

defective.
Faders: If the voltage of the signal line does not
change between 3.3

defective.
Tempo slider: If the value of the voltage of the
AD_PITCH1/2_2 signal is other than 1.65

the voltage of the AD_PITCH1/2_1 signal does
not change between 3.3

If other switches that are connected to the same
signal line operate normally, the corresponding

corresponding switch may be defective. If other
switches do not operate either, a transistor in the
switching-detection section or its peripheral
