OPERATION
1. Turn on the power using the On/Off switch located on the front
of the power supply. Brightness can be adjusted by rotating the
illumination level knob.
NOTE:
The maximum position is for intermittent use only.
Continuous use will shorten lamp life.
2. Insert the Focusing Rod in the pivot post of the instrument
body to make rough IPD and focus adjustments.
3. Position the light onto the flat surface of the focusing rod and
adjust the pupillary distance and focus of the eyepieces to suit
the needs of the operator. Refer to figure-12.
4. Using the Slit Width Knobs, adjust the projected slit so that the
thinnest slit is shown on the Focusing Rod. Refer to fig.-12 & 15.
NOTE:
The thinnest line will allow for greater accuracy.
5. Remove the Focusing Rod.
6. To position a patient, adjust the chinrest height by turning
the Chinrest Elevation Handle on the post of the Chin Rest
Assembly until the patient’s canthus is in line with the canthus
mark on the chin rest post. Refer to figure-13.
7. Microscope elevation is adjusted by rotating the joystick and
observing the slit image through the Microscope Assembly until
slit is centered on the patient’s cornea. Refer to figure-14.
8. Move the slit lamp with the joystick held firmly and slightly
angled toward the patient, until the slit appears sharply on the
cornea.
NOTE:
The accuracy of this rough adjustment should be checked
by the naked eye. The fine adjustment is performed while
observing the slit through the microscope.
9. Tilt the Joystick, which is now held lightly at its upper end, until
the slit appears sharply at the depth of the eye which is to be
observed.
10. The horizontal motion of the base can be locked by tightening
the Base Locking Screw. Refer to figure-14.
NOTE:
Lock the base whenever the lamp is not in use.
11. The slit width can be adjusted by rotating the Slit Width/
Rotation Knob on either side of the instrument. Refer to figure-15.
