Notes:
The PMD661 plays during closing and holding the PLAY switch, and skip
back then pause at the point when It opened.
Resistance error - Within 5%.
Never apply external voltage. Doing so will result in malfunction.
Insulate the circuit so that it cannot be touched directly. Use a structure that
protects the circuit from static electricity, which will cause malfunction.
