OPERATIONS IN USE
2Turn the peripheral observation prism so that its slope surface direction is opposite to the
direction of the periphery to be observed.
Turning the peripheral observation prism greatly alters the condensing point of the
illumination light emitted from the front lens.
3Move the microscope horizontally with the X-Y translator so that the condensing point of the
illumination light emitted from the front lens is aimed at the pupil of the patient's eye.
For safety’s sake, carry out the above adjustment watching the patient’s eye directly,
without using the microscope.
4While watching the patient's eye through the microscope, remove flare (fine movement of the
front lens) and perform focusing (focus up/down switch operation).
5When you change the position of the periphery to be observed, also perform the above 2 ~ 4.
OPERATION OF INVERTER: OFFISS, OFFISS Lite
You can set the inverter to IN/OUT with the inverter in/out switch of the foot switch regardless of the
front lens status.
1Press the inverter in/out switch of the foot switch.
2Each time the switch is pressed, the IN/OUT change is repeated. The IN indicator LED lights up
for the inverter IN status and switches off for its OUT status.
