  • Page 17: Adjustments In The Service Mode

    ADJUSTMENTS IN THE SERVICE MODE Since some chassis circuit adjustments are controlled by the CPU built into the chassis, adjustments can now be made by inputting data directly via the remote control handset supplied with the set. Memory IC replacement Since adjustment data for the circuit is stored in the memory IC (IC802) that comes with the CPU, the adjustment data must be re-input when the memory IC is replaced.
