-2-2 Oscillation Circuit
This circuit generates the base clock for calculating time and the synchro clock for transmitting data from and to the inside
logic elements of the IC1 (MICOM). Be sure to use specific replacement parts, since calculating time by the IC1 may be
changed. If changed, the OSC1 SPEC will not work.

-2-3 Reset Circuit
The RESET circuit allows all the functions to start at the initial conditions by initializing various parts, including the RAM
inside the MICOM (IC1) when the power is initially supplied or the power supply to the MICOM is restored after a
momentary power failure. For the initial 10ms of power supply, LOW voltage is applied to the MICOM RESET terminal.
During a normal operation, 5V is applied to the RESET terminal. (If a malfunction occurs in the RESET IC, the MICOM will
not operate.)
