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 unit supplied with the set.
Memory IC (lC805)replacement
Since adjustment data for the circuit is stored in the memory IC (IC805) that comes with the CPU, the adjustment data
must be re- input when the
memory
IC is replaced.
(After memory IC replaced, reference data is initially written automatically to memory from the CPU ROM for basic set
operation.)
