PRECAUTIONS BEFORE
SERVICIN
Hi Precautions for measuring of the output waveforms.
t
2.
3.
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.
Since the 1/10 test probe is used, the indicated voliage value on the bottom part of each waveform photo is 1/10 of the actual
value (e.g. 0.2 V/cm should be 2.0 V/cm).
To measure the waveforms, first set this unit to the self-diagnostic mode (refer to page I-14, No. 3). The Wave ROM output will
then be output as a sine wave to facilitate the servicing check. :
Hi Important safety notice:
i Symbolic Marks
‘Components identified bya /\ mark have special characteristics impotant for safety. _
When replacing any of these components, use only manufacture’s specified parts.
The symbolic marks for resistors and capacitors which used in this circuits are classified as following TABLE-1 and TABLE-2.
1.
. CAPACITORS
RESISTORS
Resistors without symbolic mark are FIXED CARBON FILM RESISTORS (ERD-type).
* All resistors are 1/4 WATT, +5 % TOLERANCE unless otherwise designated in schematic diagrams.
