1. On “MENU”, select “INSTALL SETTING”, and set “Test Pattern” to “ON”.
2. Adjust the focus to the optimum position while observing the test pattern at the center of the projected image. (If “Test Pattern” is set to “ON” in step 1, a cross-shaped test pattern appears when the Focus key is pressed.)
3. Press the AF adjustment switch (1) in the following figure and hold it for about two seconds. (When the holding action is recognized, the focus starts functioning automatically.)
Note:
While holding down the key, ensure that no object that may interrupt the projected image exists in front of the AF module (2) , or between the VPL-CX75 and the screen.
