Canon CR-2 26

4 Basic Operations

2Tilt the operation lever forward or backward to unify the top and bottom of the image of the pupil.

When the pupil is smaller than the inner pupil alignment circle, images cannot be taken properly.

Darken the room further to dilate the patient's pupil more. If the patient's pupil does not dilate enough, use the small pupil photography function (see page 30).

Press the alignment button.

The retina appears in the observation monitor and the internal eye fixation lamp blinks for three seconds.

Adjust the observation light brightness with the observation light brightness button.

Guidelines for observation light brightness

Adjust to the lowest possible brightness level to reduce the strain on the patient's eye.

Observation monitor brightness adjustment

Use the Rics NM 2 to adjust the brightness of the observation monitor. See the Rics NM 2 manual for details.
