1-5 Notes When Using Service Manual
(1) Value units used in parts list
Certain symbols are indicated as shown below for value units of resistors, capacitors and coils in
parts list. When you read them, note the following regular indications:
(2) Values in schematic diagrams
The values, dielectric strength (power capacitance) and tolerances of the resistors (excluding
variable resistors) and capacitors are indicated in the schematic diagrams using abbreviations.
Certain symbols are indicated for value units: When you read them note the regular indications in

(3) Identifications of sides A/B in circuit board diagrams
1) Board with a pattern on one side and parts on both sides:
Side A: Shows discrete parts, viewed from the pattern side.
Side B: Shows leadless parts, viewed from the pattern side.
2) Board with patterns on both sides and parts on both sides:
Side A: Shows parts and patterns which can be seen when the case is opened.
Side B: Shows parts and the pattern on the back of side A.
