Service Mode Adjustments
[1] Bus Data Adjustments
Note: The CPU (IC801) and memory IC (IC802) store the service adjustments data and controls data for each circuit.
When the Memory IC(IC802) is replaced, some of the service adjustments should be readjusted to obtain the
best performance. The necessary service adjustments are carried out by using the RC handset.
Following table shows the initial values which have been stored in the CPU ROM, and items for the service
adjustments.
