3-1.Cautions
Precautions in parts replacement
Do not reuse detached electronic components. Use only new components.
The negative side of tantalum capacitors is weak against heat. Handle with care.
With the exception of Chemical capacitor and tantalum capacitors, the voltage of capacitors of a 50V or lower withstand voltage
is not labeled.
Unless specified, electronic component resistance is 1/16W.
K = 1000 , M = 1000 K
