8. Precautions before Servicing
8.1. 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).
3. To measure the waveforms, first set this unit to the service
diagnostic mode (refer to “WAVE ROM test”). The WAVE ROM
output will then be output as a sine wave to facilitate the servicing
check.
8.2. Important safety notice
- Components identified by a mark have special characteristics
impotant for safety.
- When replacing any of these components, use only manufacture’s
specified parts.
