					• When one of F0 to 2047 (F0 to 2047 for AuA and
					AnU) is turned on by						SET F				1 is added to the
					contents of SD63. When								RST F					or		LEDR
			Annunciator		instruction is executed, 1 is subtracted from the
				Annunciator	contents of SD63. (If the INDICATOR RESET switch
D9124	SD1124	SD63	detection
				detection quantity	is provided to the CPU, pressing the switch can
			quantity
					execute the same processing.)
					• Quantity, which has been turned on by																SET F			is
					stored into SD63 in BIN code. The value of SD63 is
					maximum 8.
D9125	SD1125	SD64			• When any of F0 to 2047 is turned ON by																				, F
																						SET F
					numbers turned ON sequentially are registered into
					D9125 - D9132.
D9126	SD1126	SD65			F numbers turned OFF by									RST F					are deleted from
					D9125 - D9132, and move to data registers
					subsequent to the ones that stored deleted F
					numbers. Execution of							LEDR				instruction shifts up
D9127	SD1127	SD66			SD64 - SD71 contents one place. (When CPU has
					INDICATOR RESET switch, pressing that switch
					performs the same processing.) When there are eight
					annunciator numbers detected, the ninth number is
D9128	SD1128	SD67			not stored into SD64 - SD71 if detected.
