For resistors and capacitors in the circuit diagrams, their resistance values or		B
capacitance values are expressed in codes:		CN1801
Ex. *Resistors
Code	Practical value
123	12k ohms
103	10k ohms
*Capacitors
Code	Practical value
103	0.01uF
101/10	100uF/10V

The > mark found on some component parts indicates the importance of the safety factor of the part. Therefore, when replacing, be sure to use parts of identical designation.
