My finger touch position is not accurate. What should I do?
You need to perform finger touch calibration. See below.
Calibrating for Finger Touch InteractivityFinger touch calibration coordinates the positioning of your finger with the location of the cursor.
Note: Make sure you have calibrated the pens, installed the Touch Unit, performed angle adjustment, and turned the Touch Unit on before calibrating for finger touch interactivity.
- Press the Menu button, select the Extended menu, and press Enter.
- Select the Easy Interactive Function setting and press Enter.
- Select Touch Unit Setup and press Enter.
- Select Touch Calibration and press Enter.
The following screen appears:
Note: If Touch Calibration is disabled, make sure Power is set to On.
- Adjust the image focus, if necessary.
- Press Enter to select Yes. A flashing green circle appears in the upper left corner of your projected image.
- Touch and hold the center of the circle with your finger until the circle disappears and another circle appears, then release it. The circle disappears, and you see another circle below the first one.
Note: For the most accurate calibration, make sure you touch the center of the circle with the tip of your finger.
Note: Make sure you are not blocking the signal between your finger and the interactive receiver (next to the projection window on the projector).
- Touch the center of the next circle with your finger and continue until all of the circles disappear. When you get to the bottom of a column, the next circle appears at the top of a new column.
Note: If you make a mistake, press the Esc button on the remote control or control panel to go back to the previous circle. To restart the calibration process, press and hold the Esc button for 2 seconds.
- If the cursor location and your finger position do not match, repeat these steps to calibrate again.
