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.
