HFC
All parameters return to the factory settings.
Any of four different clear operations is performed according to the data.
When all parameter clear is executed for H9696 or H9966, communication-
related parameter settings also return to the factory settings. When resuming
operation, set the parameters again.
*Pr. 75 is not cleared.
