POWER
- ● Vcc(DC 5V)
- ▶ V12(DC12V)
AC220V input power is decompressed through LVT(DC-TRANS), the power is changed DC vltg through DIODE rectification. It is
an archery practive bow through 1000uF/35V CAPACITOR. And regular DC 12V is output through REGULATOR 7812, it is used
to the RELAY runing power. The other of LVT(DC-TRANS) is an archery pratice bow through DIODE rectification or 1000Uf/35V
CAPACITOR and it is output the regular DC5V through REGULATOR 7805.
And it is used sircumference circuit or various signal(Sensor,Switch) input power.

9-2. Departure circuit PART

Element of inside MICOM is copper ware clock production of informations transmission, reception and eruption circuit for time calculation.
In a case change SPEC of X-TAL use the standard parts or SPEC because it changes calculated time at MICOM or doesn't run.
