If the calibration is not completed properly, the beeper will sound and the LCD panel
display items will blink. In such a case, press the shutter button again and start again
from step 4.
• Calibration may not be possible if you wear mirror-type sunglasses.
• If Eye-Control AF cannot be used, use automatic or manual focusing point
selection. See page 38.
Eye-Control Calibration Refinement
Eye-Control precision can be improved by repeating the calibration
procedure under various conditions (outdoors, indoors, at night, etc.) for
the same channel No. The additional eye-related data can accumulate in
the same channel No. for both the horizontal and vertical camera
orientations.
• A calibration channel must not store calibration data for more than one person. Otherwise
Eye-Control precision will be affected. A different user should use a different calibration
channel that is available. Or, existing calibration data should be deleted to store new
calibration data. See page 46.
Calibration Tips
• Relax your shoulders and hold the camera steady in a natural posture.
• Align your line of sight with the center of the viewfinder.
• Instead of looking at the blinking focusing point itself, look at the point beyond it.
• If you wear eyeglasses, wear them properly without having them slide down your
nose.
CAL is an abbreviation for calibration.
