2.4 SELF-DIAGNOSIS RESULT DISPLAY
The "SELF-DIAGNOSIS RESULT DISPLAY & MEMORY function is built in this VTR.
It means that when the VCR detects undesirable condition, it can be displayed a “Error code (Two
numbers from the right)” with Service Mode 2.
Since the "Error code" is stored in the EEPROM, it can be displayed although after disconnected the
AC leads. It can be displayed with Service Mode 2.
(If a second error had been detected, only the most recent error is displayed. )
For more details, refer to the Service Manual for Z-Mechanism Chassis Order number
VRD9802005C2.
