(VHS) Self-Diagnosis and Special Mode Setting

8.2.1. (VHS) Self-Diagnosis Functions
This model has a self-diagnosis and display function. If the VHS section detects trouble during installation or during use, one of the
following Error Codes will automatically appear in the display on VHS side. Error Codes are displayed in the form of a single English
letter followed by two numbers, as for example "H01".
Note:
1. The indication "U" is displayed on the FIP while power remains on.
2. 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 Error indication code will disappear and the unit will return to normal display mode (either clock or counter is displayed).
3. This Error indication code will be stored in the microprocessor even after the AC plug being disconnected.
The two-digit number portion of the stored Error indication code can be re-displayed in "second" display portion (the last 2 dig-
its of the FIP) by placing the unit is Service Mode Number 3 When turning on Service Data Display as for example "01" or "02"
etc. If a second error occurs, the most recent error will be displayed and stored until 3 self-diagnosis histories in maximum.
4. To erase the stored Error Code data, Press FF and EJECT buttons on VCR simultaneously for over 5 seconds in Service
Mode 3.
