  • Page 11: Service Mode Adjustments

    Adjustments in the Service Mode Since some chassis circuit adjustments are controlled by the CPU built into the chassis, adjustments can be made by inputting data directly via the remote control handset supplied with set. [Memory IC replacement] Since adjustment data for the circuit is stored in the memory IC (IC802) that comes with the CPU, the initializing of the memory IC and re-inputting of the adjustments data must be made when the memory IC is replaced.
