ADJUSTING PROCEDURE OF EACH SECTION
The best adjustment is made before shipping. If any position deviation is found or after part replace is performed, adjust as follows.

1. Preparations for Adjustments
Use the specific AC adaptor or a regulated DC power supply. AC adaptor : UADP-0209CEZZ (Type 10 non-polar LC10A3H/M) DC power supply : 12 V, 3.2 A

2. Calling the adjustment process mode
The mode can be called up in the following two ways. » Set either the KEY4 (Pin 81 of microprocessor) or KEY5 (Pin 82 of microprocessor) to the L level and turn on the power.

3. Key operation in adjustment process mode
Selecting a reception channel » Using the CH UP/DOWN keys, search up and down a reception channel. Clicking on the keys : Channels are selected up or down one by one. Holding down the keys : The next receivable channel is searched up or down. » Various adjustments Each of the adjustments is made by selecting an item on the menu and using the CH UP/DOWN and VOL UP/ DOWN keys (on the TV set and remote controller). » Using the menu select key, the adjustment items are picked up alternately. (Picking the next item) When the bottom item is selected and the menu select key is activated, the top item on the next page will be selected instead. » Using the picture select key, the adjustment items are picked up alternately. (Picking the previous item) When the top item is selected and the picture select key is activated, the bottom item on the previous page will be selected instead. » When an item is selected and the auto preset key is activated, the top item on the next page will always be selected. Page 1 � Page 2 � ... � Page 15 � Page 1 ... » When an item is selected and the manual memory key is activated, the top item on the same page will always be selected. Using the VOL UP/DOWN keys, the setting of the selected item can be turned up or down. » Suppose PAL/NTSC is selected for p.14 and p.15. Using the VOL UP/DOWN keys, the register select mode is called and the cursor goes to Address 01. » The CH UP/DOWN keys are used to move up and down the cursor and the VOL UP/DOWN keys to move it right and left.

Example : 02 �� 05 �� ... �� 06 �� 02 �� ...

4. Initialization
Here is the procedure of initializing the EEPROM and making model number and size settings. 4-1. Get Pins (81) and (82) of the IC2001 (microprocessor) grounded and turn on the power. 4-2. Select a model number (A1, A2H, A2U). For Models LC-10A3H and LC-10A3M, select A2H. 4-3. Select a size in inches (10, 12, 15, 20). For Models LC-10A3H and LC-10A3M, select 10. 4-4. Get Pins (81) and (82) of the IC2001 (microprocessor) back to normal.
