A1 CPU Replacement
When you replace a faulty A1 CPU with a new one, remove the EEPROM from the faulty A1
and mount the EEPROM on the replacement A1.
In the EEPROM, the correction constants data is stored after performing the Adjustment and
Correction Constants procedures described in the chapter 5. The data may be valid for the new
A1 CPU.
