13.1. Precautions for measuring of the output waveforms
1. The waveform was measured with a "National Digital Storage
Oscilloscope VP-5730A". Therefore the waveforms of musical tone
signals shown may differ somewhat due to the difference in the
timing of triggering.
2. Since the 1/10 test probe is used, the indicated voltage value on
the bottom part of each waveform illustration is 1/10 of the actual
value (e.g. 0.2 V/cm should be 2.0 V/cm).
TEST MODE
Press and hold the two F keys shown below, and then turn
power switch.
Press and hold the two G keys shown below, and then turn
power switch.
