Service Adjustments
On-screen Service Menu
Following table shows the initial values which have been stored in the CPU ROM, and items for the service adjustments.
When IC802 (EEPROM) is replaced, check the bus data to confirm they are the same as below. The shaded menu should be
checked and be set up or readjusted according to the procedures described in the following pages.
Initial Setup Data marked with an
