Hi, in memoriam No Adjust! - In this case, it means the contents of the EEPROM is damaged. Before the error "no adjust" occurs, You can copy the contents of EEPROM. When an error occurs, you can upload the memory dump to the chip. EEPROM: IC302 Seiko Instruments S-93C46AMFN Buffer content from address: 00000000h, to address: 0000003Fh memory for user settings and adjust settings Programmer: Elnec BeeProg+ BAT300, battery backup (3V ML614 rechargeable lithium battery) is only for Real Time Clock cross-reference: Panasonic EECEN0F204RK http://www.tme.eu/en/details/eec-en0f204rk/supercapacitors/panasonic/eecen0f204rk/ Caution: Connect an AC adapter after replacing battery, and leave the unit for more than 8 hours.
