Self-Testindicationdisplay - Panasonic REV-1 Service Manual

6. SELF-TESTINDICATIONDISPLAY
This VTR has a self-diagnosis and display function. If the VTR detects trouble during installation or during
use, one of the following fault indication codes will automatically appear in the VTR display. Fault indication
codes are displayed in the form of a single English letter followed by two numbers, as for example "HOI".
Note: 1. The indication "U" is displayed on the FIP while power remains on.
2. Otherwise, the indication "H" or"F" is displayed on the FIP, and the power is automatically turned
off.
When the power is turned on again, the fault indication code will disappear and the unit will retrun
to normal display mode (either clock or counter is displayed).
3. This fault indication code will be stored in the microprocessor even with the AC plug discon-
nected.
The two-digit number portion of the stored fault indication code can be redisplayed in the FIP's
"second" display portion (the last 2 digits on the light) by placing the unit is Service Mode Number
2 when turning on Service Information Display as for example "01" or "02" etc.
If a second error occurs, only the most recent error will be displayed and stored.
4. To erase the stored fault indication code data, press FF and EJECT buttons for 5 seconds.
