OPERATING PROCEDURE : Optional functions
2.6.3 Alignment area change
When low-sensitivity auto tracking is used ( : blue) or the auto tracking is not used ( : black and
white), the alignment area can be changed at the time of image capture of peripheral areas depending on
the internal fixation lamp position.
Setting of “Alignment area change”
Control menu: Photography settings—Photography options, Alignment area change—ON (default)
When “Alignment area change” is set to ON, the target mark changes to various elliptic shapes depending
on the internal fixation lamp position at peripheral areas.
When the patient gazes at the blinking interior fixation lamp at peripheral areas, the image may be obscured
by iris. The elliptic target mark helps avoid such a case by allowing the electronic working dot to be manually
moved within it toward the pupil center.
For details of setting, see “
 Photography options” (Page 113).
