SELF-DIAGNOSIS FUNCTION
1.
Self-diagnosis Function
When problems occur while the unit is operating, the self-diagnosis
function starts working, and displays on the viewfinder or Display
window what to do. This function consists of two display; self-
diagnosis display and service mode display.
Details of the self-diagnosis functions are provided in the Instruction
manual.

window what to do. This function consists of two display; self-
diagnosis display and service mode display.
Details of the self-diagnosis functions are provided in the Instruction
manual.
Note: The “self-diagnosis display” data will be backed up by the coin-type lithium battery (CF-2500 block BT101). When the
CF-2500 block is disconnected, the “self-diagnosis display” data will be lost by initialization.
2.
Self-diagnosis Display
When problems occur while the unit is operating, the counter of the
viewfinder or Display window shows a 4-digit display consisting
of an alphabet and numbers, which blinks at 3.2 Hz. This 5-character
display indicates the “repaired by:”, “block” in which the problem
occurred, and “detailed code” of the problem.
