Hi Steve
I understand what you are saying but anything is worth a shot even if the probability is very low.
There must be more to the eeprom data than what the manual is stating and the only device that can write to this device is the MCU.
If the MCU detects something is not normal it may write or delete some data either in the eeprom or MCU flash.
This may not be by design as well but a software glitch which was overlooked due to the developers thinking that a US logic board will never find its way into a Japanese radio albeit a radio that was probably put together using faulty components just to make a sale.
regards
James
