3.2 circuit description 3.2.1 power circuit POWER VOLTAGE (+5V,-30V,V ,,VF1,VF2) REGULATOR CIRCUIT After passing through the switching regulator. There is a +24V DC power via JP1. This power supply circuit employs fly back converter type switching regulator system. At the initial condition, as the level of point “I” is 0V, PQ4 keeps OFF condition. When +24V begins to rise up after power ON, the level of point “H”... -
Page 9: Key Board Circuit
3.2.2 KEY BOARD CIRCUIT Input and output signal for key board scanning are passing through J1,J2 The output signals from output port (P110-P113) of U17 are encoded signals. By passing through U25,U26(74HC138), they are decoded to key scan signals. And they are applied to key matrix via J1. -
Page 10: Display Circuit
3.2.3. display circuit Display signals are applied to the display circuit board via J4.. The display signals for digit indication are also used for key scan signals which are decoded At U25,U26(VHC138). The decoded signals from U25,U26 are amplified at U23,U24(driver:uPA80C) and applied to the display tube on display circuit board. -

Similarly after JF_I0,JF_I1 set to “L” level, the signal JF_PH1, JF_PH2 are sequentially changed for to feed the journal paper. +24V 0.1u PGND... -
Page 14: Battery Charge Circuit
3.2.9. Battery charge circuit When the power is turn on, D12 and D13 turn on, thus +5V is applied to VBB line and Recharge current is applied to the rechargeable battery via R31. When the power is turned off, D12 and D13 turned off, thus battery output is applied to VBB. When the power is turned off, battery output backs up the memory contents of RAM chip and CPU internal RAM. - Page 15 PF signal timing chart...
