This section explains the contents of SELF-DIAGNOSIS.
For information on how to operate the Screen,
for information about how to set up the Special Tools,
DISPLAY PATTERN
Used when the buzzer will not sound and when the device contents will not display correctly to check the
drawing function. It does this by running checks on the various screen pattern displays (8 screens), the ON/
OFF Display, and KANJIROM CHECKSUM. When the ON/OFF Display is checked, the Buzzer ON/OFF
check is run simultaneously. If KANJIROM CHECKSUM is normal, OK displays; if there is a problem, NG
displays.
TOUCH PANEL
Touch Panel check. Checks if each touch cell highlights when pressed.
INTERNAL FEPROM CHECKSUM ( Protocol)
The Internal FEPROM System and Protocol check searches for any problems that may arise during opera-
tions. When running the check, the screen will change as follows.
When the FEPROM is normal, OK displays; if there is a problem, the screen stops in the middle of operation.
This check does not erase the System or Protocol.
FRAME BUFFER
The Frame Buffer (display memory) Check looks for any display problems that may develop. When every-
thing is normal, OK displays; when there is a problem, an error message displays.
