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 on SERVICE
DIAGNOSTIC FUNCTION ”). The WAVE ROM output will then be
output as asine wave to facilitate the servicing check.
9.2. Important safety notice
- Components identified by a mark have special characteristics
important for safety.
- When replacing any of these components, use only manufactures
specified parts.
9.3. Symbolic marks
The symbolic marks for resistors and capacitors which used in this circuits are classified as
following Table-1 and Table-2 .
9.3.1. 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.
