BASIC OPERATIONS
• If the image of the pupil is not shown on the screen, use the control lever to move the
measuring head into the proper position, locating the patient's pupil.
For the operation of the control lever, see "OPERATING THE CONTROL LEVER" on
page 31.
3
When the pupil image is seen on the screen, tap the luminous point of the center part to
start measurement, or press the MEASUREMENT switch on the control lever. The
main body will move into the position where the pupil image and luminous point come on
the screen center.
4
Confirm that a coaxial ring image is seen at the center of the pupil image.
• If the coaxial ring image cannot be recognized, it may be outside the auto alignment
range. Using the control lever, move the main body forward and into to a position where
the ring image can be seen.
If the coaxial ring image is not visible, measurement will not start automatically, even if
AUTO mode is set.
5
When the auto alignment range is reached, the main body performs an auto focusing
function to finalize alignment, and will start the measurement process automatically.
Even in steps
2
to
4
, the main body starts measurement automatically when the auto
alignment range is reached.
If a limit message " " appears during auto alignment, indicating that the main body has
reached the maximum limit of movement, manually operate the unit, using the control
lever, toward the direction of proper alignment.
Limit message:
: When the main body exceeds the limit to the left (to the patient's right eye), a
message "Move to the right" is displayed.
: When the main body exceeds the limit to the right (to the patient's left eye), a
message "Move to the left" is displayed.
: When the main body exceeds the limit to the front (to the operator), a message
"Push backward" is displayed.
: When the main body exceeds the limit to the rear (to the patient), a message
"Pull forward" is displayed.
Auto alignment is not done while the control lever is in use.
To enable a smooth auto alignment operation, do not utilize the control lever.
When the measurement of the first eye is complete and the measuring head moves to
the other eye, a limit message may be displayed if the measuring head cannot locate the
patient's pupil on the second eye, and measurement on the second eye will not be per-
formed. If this occurs, check to confirm the patient's head position is centered in the head-
rest, and the chinrest is at the proper height.
6
When the measurement of one eye is finished and when R/L continuous measurement is
selected, the measuring head moves automatically to the measurement position of the
other eye.
