Laser Beam Aligning
1. Align the Vertical Beam with the center of the face (Mid-sagittal Line). (It's to prevent
horizontal expansion of the image)
2. Align the Horizontal Beam in a straight line to the Frankfurt Line on the patient's face.
Use the Horizontal Beam button on the control panel to position it. Make sure that the
Horizontal Beam is aligned to the patient's face horizontally.
Finishing Patient Positioning
1. After checking the positions of the patient and the Laser Beam, click the Temple
Supports Open/Close button on the control panel to prevent the patient's head from
moving.
2. Click the READY button. The X-ray exposure has not started yet.
3. Now go to 3.3 X-ray Exposure to start the exposure.

Be careful not to shine the laser beam directly into the person's eyes.
Doing so may result in vision loss.
If the laser beam is not correctly positioned, there may be distortion,
causing the image to be enlarged or reduced, or ghost shadows may
occur and lower the image quality. Be sure to align the Laser Beam
properly.
Make sure that the Temple Supports are in CLOSE position before
clicking the READY button.
