Initial data of Main FPC unit for repair parts : Fixed data and roughly data are written in FPC assembling. Standard data : These are general data. Data are not yet decided. : Do not change the data address 52 to 127. Note 1/2
x Meaning of address 30 flag data (different from old type CPU)
128 : Power voltage falls below DC/DC converter guaranteed voltage level. 64 : Closing curtain SWfails to turn on even if closing curtain Mg turns off. 8 : Mechanical pulse fails to be output 255ms during charging. 4 : X contact is closed without T setting. 2 : Correct pulses are not output while aperture control is carried. 1 : 40 m more aperture pulses are generated after aperture Mg turns on.
If the above number is writen in the address 30 of EEPROM, it means that the mentioned trouble happened in the camera. If two or more
troubles have happened, added number is shown. For example, If the number in address 30 is 192, troubles mentioned in '128 and 64" in the past. Note : 1. If the shutter is released while depth-of-field oreview button is depressed, the number `2" is written in address 30. The actual trouble did not necessarily occur. 2. After rewi r, be sure to change the number in address 30 to * EEPROM list of Malti Photomic Finder
