3.2.2 PF CIRCUIT Power ON When AC input turn ON, the level of U12-11 rise up to +4.3V. When input voltage of U12-11 become 3.3V, the output of U12-12(nPF) turn “H”. Then system goes to operation mode. Power OFF When AC input turn OFF, the level of U12-11 fall to 0V. When input voltage of U12-11 become 2.2V, the output of U12-12(nPF) turn “L”. -
Page 9: Key Board Circuit
3.2.3 KEY BOARD CIRCUIT Input and output signal for key board scanning are passing through CN13~CN15. The output signals from output port (P140-P143) of U11 are encoded signals. By passing through U21,U22(74HC138), they are decoded to key scan signals. And they are applied to key matrix via CN15. -
Page 10: Display Circuit
3.2.4. display circuit Display signals are applied to display circuit board via CN3. The display signals for digit indication are supplied from P120 to P127 and P145,P146 of CPU ports. The digit indication signals are amplified at 9 FETs.(2SJ208) And they are supplied to LED common terminal on FD and supplied to RI ones. -
