The adjustment values are set to their optimum at the factory before shipping. If by any chance a value should become improper or a readjustment is
required due to part replacement, make an adjustment according to the following procedure.
Before adjustment, perform aging for approx. 60 minutes to stabilize the unit.
1. Entering the adjustment process mode
There are 3 ways as follows:
• After power-on, press "ADJUSTMENT PROCESS" key of the remote control.
• With the KEY 4 (pin E1 of IC801) set to "L", turn the power ON.
• During servicing
1
While holding down the TV/VIDEO and Volume DOWN keys at the same time, set the Power switch to ON. (“K” standing for inspection process
mode is displayed in the upper left portion of the screen.) → Press the Channel DOWN and Volume DOWN keys at the same time. (The adjustment process mode screen appears.)
To cancel it, turn off the power using the Power switch or remote control.
2. Key operation in the adjustment process mode
1. Basic operations
• Tune in to a station using the Channel UP/DOWN keys.
• Switch the input using the TV/VIDEO key.
• Select an item to adjust using the Cursor / keys. (Pressing the Cursor key while at the bottom item moves to the top item on the
next page, and pressing the Cursor key while at the top item moves to the bottom item on the previous page.)

• Press the Menu key to move to the next item. (Pressing the Menu key while at the bottom item moves to the top item on the next page.)
• Press the Manual Memory key to return to the top item. (Pressing the Manual Memory key while at the top item moves to the top item on the
previous page.)
Press the Auto Preset key to move to the top item on the next page.
2. Layer movement
• Pressing the ENTER key while at an item other than I2C DATA and HOTEL POWERFIX on page 2 moves to the setting page of that item
name.
• Press the Flashback key to exit each setting page.
3. Adjustment procedure for RGTAR, GGTAR and BGTAR items on pages 3, 4, and 5 of the DVP layer
• At RGTAR, GGTAR, and BGTAR on pages 3, 4, and 5; pressing the Volume UP/DOWN or the Cursor / keys moves left or right.
Select an item to adjust, and press the Direct Channel "12" key.
As the Cursor moves to the corresponding right field, make adjustments using the Volume UP/DOWN or the Cursor / keys. Pressing the
Direct Channel "12" key at the right field moves back. Pressing the Cursor / keys, the Menu key, etc. moves to a different item.
