3-1.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.
* 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.
