		CONVENIENT: The BPF T1–BPF T4 can be adjusted automatically.
			-1: Set the cursol to “BPF ALL” on the adjustment program and then push [ENTER]
			key.
			-2: The connected PC tunes BPF T1–BPF T4 to peak levels.
			or
			-1: Set the cursol to one of BPF T1, T2, T3, or T4 as desired.
			-2: Push [ENTER] key to start tuning.
			-3: Repeat -1 and	-2 to perform additional BPF tuning.
