SELF-DIAGNOSIS FUNCTION
1. Self-diagnosis Function
When problems occur while the unit is operating, the self-diagno-
sis function starts working, and displays on the LCD monitor 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 Instruc-
tion manual.
Note: The “self-diagnosis display” data will be backed up by the coin-type lithium battery (VD-032 board BT701). When this
coin-type lithium battery 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 time code of
the LCD monitor shows a 4-digit display consisting of an alpha-
bet and numbers, which blinks at 3.2 Hz. This 5-character display
indicates the “repaired by:”, “block” in which the problem oc-
curred, and “detailed code” of the problem.
3. Service Mode Display
The service mode display shows up to six self-diagnosis codes shown in the past.
3-1. Display Method
Set the “DISPLAY SELECT” switch to “DATA”, turn on the power by the “POWER” switch while pressing the “STOP” key, and continue
pressing the “STOP” key for 5 seconds continuously. The service mode will be displayed, and the time code will show the backup No. and
the 5-character self-diagnosis codes.
3-2. Switching of Backup No.
By pressing the “ F ” or “ f ” key, past self-diagnosis codes will be shown in order. The backup No. in the [] indicates the order in which the
problem occurred. (If the number of problems which occurred is less than 6, only the number of problems which occurred will be shown.)
