PROTECTION CIRCUIT
   If the temperature inside the CA260 rises above 80 Degree-C the protection circuit comes into operation, decreasing output. At this time the protect indicator blinks. If the temperature comes back below 80 Degree-C by natural cooling, output returns as it was.
   If the temperature rises above 100 Degree-C, the power supply circuit is shut off. Not only does the output stop, but also the protect indicator goes out. If this happens, it is possible that the CA260 is broken. However, even in this state, it cannot be always said that it is broken because the unit may operate when the temperature comes back below 80C by natural cooling.
