1.Notes on Schematics Diagrams
Other neccessary notes are shown in each block.
1-1.Cautions
Caution when replaceing chip (leadless) parts.
* Do not re-use the removed parts, but use new parts.
Be careful that the negativ side of the tantalum capacitors are susceptible to heat.
* Voltage indications are omitted for capacitors other than chemical and tantalum capacitors with a dielectric strength of
50 V or less.All units are uF (p shows pF).
* Chip resistors without indication are 1/10 W.
* k=1000 , M=1000 k
* Variable resistors and semi-variable resistor are abbreviated the specification of B characteristic.
