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 chapter 3. The data may be valid for the
new A1 CPU.
