reason, e.g., after parts replacement, follow the instructions shown below.
2. Control parameter values set in the in-process adjustment mode has been stored in the corresponding registers.
When the product is readjusted, the contents of the registers are changed. Before readjustment, factory settings
should be noted in case the contents of registers require to be restored.
3. Use a stabilized AC power supply.
4. To rewrite a program, you should note the items ("OSD MENU" and "Adjustment Values") you want to change
and initialize EEPROM, and then rewrite the changes into EEPROM.
How to enter the in-process adjustment mode
1. Entering the in-process adjustment mode:
Connect the system cable between the display and AVC system.
Turn on the main power while holding down the "INPUT" button and the "Volume (-)" button of the display
simultaneously. The system will be activated.
~If you see multiple lines of blue characters on the display, you are in the in-process adjustment mode. If not
(the normal activation screen opens), retry.
2. Accessing the inspection process mode:
After activation of the system, make adjustments according to the instructions indicated on the process adjustment
OSD menu screen.
Move to the General Process Adjustment (AVC System Section Process).
3. Restoring factory settings: (At the time of "INDUSTRY INIT" execution, please wait for about 30 seconds until
/// disappears.)
When the "INDUSTRY INIT" button is selected after activation of the system, factory channel setting remains
unchanged after the system exits from the in-process adjustment mode.
Changes made by the user will default to factory settings. Note that channel setting is also initialized.
4. Exiting from the in-process adjustment mode:
Unplug the power cable while the system is in the in-process adjustment mode to exit from the mode.
Take care not to press the "Power" button on the remote controller or the AVC system after using factory
settings to run the system.
5. OSD menu screen and menu items during manual adjustment:
~The layout and menu items of the OSD menu screen may somewhat vary depending on the program versions.
~Just rewriting a program does not cause settings to be "initial values". (Preparation for adjustment)
