Self-Diagnosis Result Display; Caution For Ac Mains Lead; Self-Test Indication Display - Panasonic NV-FJ620EG Service Manual

Note:
The tape material itself is the same in both types.

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 left)" 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 VRD9612M129.
