←

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.

Symbol indicates a resistor.

No differentiation is made between chip resistors and

discrete resistors.

NOTE :

Symbol indicates a capacitor.

No differentiation is made between chip capacitors and
