Setting the Initial data

This adjustment is controlled by the CPU (IC8000) through the IIC Bus Data Line in the chassis, and those adjustment data are memorized the memory IC (IC7 00). Therefore, Main board or the memory IC (IC7 00)

is replaced, these data will be disappeared. Readjust should be made. Initial data is provided in the CPU ROM, when the memory IC (IC7 00) is replaced with new one. CPU ROM data is loaded into the memory.

Initial data is provided to operating the monitor basically. For operating the monitor quality performance, further adjustment is required following chassis electrical adjustment.

Receive good quality signal.

2. Enter the Service Mode.

3. Confirm data value to be the same as the Service Adjustment Data Table. If it is different, change to correct data
