4.15.4. Output protection:
The power amplifier is of short circuit protection function and over heat protection. Usually it is unable to be
destroyed but long time output short circuit should be avoided. The frequency, amplitude and loading should
be best within the limitation, two of which, especially, cannot get the limitation at the same time in case that
the power amplifier is damaged.
