- Calling the adjustment process mode. There are two ways to call this mode.
- Keep KEY-4 (pin (81) of microprocessor) at "L" level and turn on the power.
- For servicing:1 Hold down the "INPUT" and "VOL (–)" keys at once, and turn on the power switch. ("K" appears at the top left onscreen to indicate that the checker mode is on.)
- Press the "CH {Dn} and "VOL (–)" keys at once. (The adjustment process mode screen shows up.).
- To quit the mode, turn off the power (using the power switch on the set or the remote controller).
- Key operation: Basic operation
Using the "CH [Up | Dn] keys,
select a receiving channel.
Using the "INPUT" key,
select an input.
- Using the "cursor up/down keys, select an adjustment item. (When the "cursor down" key is pressed at the bottom item of a page, the top item on the next page will be selected. When the "cursor up" key is pressed at the top item of a page, the bottom item on the previous page will be selected.)
- Using the "VOL (+)/(–)" or "cursor right/left" keys, adjust the selected item.
- Press the "MENU" key, and the next item will be selected. (When the "MENU" key is pressed at the bottom item of a page, the top item on the next page will be selected.)

Press the "ENTER" key on any item other than I2C DATA on Page
9, the setting page of the item will show up.
To
quit the setting page, press the "FLASHBACK" key.- Initialization
- Connect both pins (81) and (82) of IC2001 (microprocessor) to GND, and turn on the power.
- Make sure the model number "A629" is selected. *Note: This setting cannot be changed.
- Make sure "13" (LC-13B8U), "15" (LC-15B8/B9U) (inches) is selected for the screen size. [Note: This setting cannot be changed.]
PUBLIC MODE SETTING
There are two ways to get the public
mode setup screen displayed.
Press the "INPUT" and "VOL (+)" keys on the
set at once and turn on the power.
Get
the password input screen displayed.
Procedure
- The input starts with the leftmost digit.
- Use the numeric keys [1] thru [9] and [10/0] keys on the remote controller. The other keys are not acceptable.
- With a numeric-key input, "–" will change to " ". The input position will move one digit to the right.
- With all the 3 digits entered, the password will be verified.
The 3-digit password is now verified.
The password [0] [2] [7] provides for
the public mode screen. (This screen comes on with whatever adjustment process
settings.)
With
any other passwords, the screen changes to the normal mode.
In the adjustment process mode, turn on
"PUBLIC MODE".
Also press the "CH [Up] and "VOL (+)"
keys on the set at once and turn on the power.
TO EXIT PUBLIC MODE
There are the following ways to quit
the public mode setup screen.
- Turn off "PUBLIC MODE" in the adjustment process mode. [This way alone is not for quitting the setup screen, but for quitting the mode itself.]
- Turn off the power with the "POWER" key. ["PUBLIC MODE" stays on in the adjustment process mode.]
- Select "ENTER". ["PUBLIC MODE" stays on in the adjustment process mode.]
- Move the cursor to "RESET" and press the "FLASHBACK" key. (Back to the normal mode screen) [The settings will be back to the factory ones.]
PUBLIC MODE SETTING VALUES
- With the factory settings made, the public mode settings get initialized. (The adjustment process remains intact.)
PUBLIC MODE MENU
The guidance is not displayed
onscreen.
Setup procedure
- To move the cursor up and down, use the "cursor UP/DOWN" key (remote controller) and "CH [Up | Dn] key (remote controller and set).
- To change the settings, use the "cursor RIGHT/LEFT" key (remote controller) and "VOL (+)/(–)" key (remote controller and set).
- To save new settings, keep the cursor at "Enter" and use the "cursor RIGHT/LEFT" key (remote controller) and "VOL (+)/(–)" key (remote controller and set).
