button of the interface.
f) Wait a few minutes Wait a few minutes Wait a few minutes to stabilize the temperature of all instrument circuits. Wait a few minutes
g) Measure the voltage between pins of the "TP" jumper head (fig. 2.9.1) with a quality digital multimeter. It
should be zero volts exactly. If it is not, adjust it with "OFFSET" variable resistor on the interface board (fig.
2.9.1).
h) Press the highest C key on the instrument's keyboard - indication bi-color LED remains off.
i) Measure the output tone frequency by the tuner (frequency meter). It should be 1046,5 Hz approx.
Remember the measured tone frequency. Then release the highest C key.
j) Press the C4 key on the master keyboard (i.e. send MIDI Note Nr. 96 to the interface) and hold it. The
indication LED will light in green.
k) Check the output tone frequency by the tuner (frequency meter) again. It must be the same as the frequency
measured in paragraph i). If it is not, adjust it with "RANGE" variable resistor on the interface board (fig. 2.9.1).
l) Release the C4 key on the master keyboard. Switch the instrument off and disconnect the power s
