Remote controller uses is the TV/NAVI remote controller AUDIO mode.

1. While pressing EJECT+SRC on the Unit (X14), press RESET key to get into the Test Mode.

2. By operating on the TEST MODE MENU screen, get into the Chroma ADJ mode. At this time, on the upper left corner of the screen [CH : 16 VCO_FREERUN, VAL : 80] OSD displa y is made . HEX display.

3. Use 8, 0 on the 10 key to change the setting value. The , the VAL number on upper-left corner of the screen changes.

4. Press PLAY/PAUSE key and confirm on the setting value. When confirmed, [CH : 16 VCO_FREERUN, VAL : 80] the color changes. When releasing the setting, press on PLAY/PAUSE key again. When released, the color changes.

5. Use 7, 9 keys on the 10 key to set the next one. The CH value changes in the upper-left corner. Repeat the same for Item 3 to 5.

6. When all adjustments are complete, press DIRECT key, which writes the adjustment values to E2PROM. At the same time, it is possible to move out of the Chroma Adjustment mode.
