SELF-DIAGNOSIS FUNCTION
The self-diagnosis function consists of error codes for customers which are displayed automatically when errors occur, and error codes
which show the error history in the test mode during servicing. For details on how to view error codes for the customer, refer to the
following box in the instruction manual. For details on how to check error codes during servicing, refer to the following "Procedure for
using the Self-Diagnosis Function (Error History Display Mode)".
PROCEDURE FOR USING THE SELF-DIAGNOSIS FUNCTION (ERROR HISTORY DISPLAY MODE)
Note: Perform the self-diagnosis function in the "error history display mode" in the test mode. The following describes the least required procedure. Be
careful not to enter other modes by mistake. If you set other modes accidentally, pull out the AC cord to turn the power off and retry to enter the test
mode.
1. Press the ?/1 button to turn he power on.
2. Press the [
AMS
] (CD) knob and [INPUT] button at the same time, press the [
AMS
] (MD) knob to display "SYS
version".
3. Turn the [
AMS
] (CD) knob and when "MD Test" is displayed, press the [
AMS
] (MD) knob.
4. Turn the [
AMS
] (MD) knob and when "[Service]" is displayed, press the [YES] button.
5. Turn the [
AMS
] (MD) knob to display "Err Display".
6. Press the [YES] button to sets the error history mode and displays "op rec tm".
7. Select the contents to be displayed or executed using the [
AMS
] (MD) knob.
8. Press the [
AMS
] (MD) knob to display or execute the contents selected.
9. Press the [
AMS
] (MD) knob another time returns to step 6.
10. Press the [MENU/NO] button to display "Err Display" and release the error history mode.
11. To release the test mode, press the [
