2.3 Inspection procedure after assembly
1. Power plug
• This instrument supplied with a 3-wire grounded line cord. Do not remove
or disconnect the ground. Please select proper power sockets and plugs
• Always ensure that the instrument is well grounded.
Important Matters
Please use the special cable supplied with this instrument.
18
2. The power box and the illumination part
• When the main power switch (8) of the power box is placed at “1” it turns
on, and when located at “0” it turns off. The main power switch should be
set to the “0” position before connecting the input cable with the power
socket.
• Turn on the main power switch, and the pilot lamp (9) will illuminate.
Open the slit width control knob (35) to examine the illumination.
• Press the brightness control switch (7) in each of the two positions, the
brightness should be change accordingly.
• Check the xation target device to conrm it is lit.
• Check that all the movable parts such as aperture and slit height control knob
(29), lter selection lever (28), and magnication lever (18), etc. move freely.
• After inspection, turn off the main power and cover the instrument with the
dust cover (O).
3. Operation
3.1 Diopter compensation and pupillary distance adjustment.
1. Use of the focusing test rod (M)

The focusing test rod is used to conrm that the microscope is adjusted correctly.
Insert it into the main shaft hole with the at surface facing the objective lens in
the direction of the user.
Important Matters
After adjustment, remember to remove the rod and insert the protective cap.
2. Brightness adjustment
Turn on the main power switch and set the brightness control switch (7) at
the “N” position. Turn the slit width control knob (35) to make the slit width
between 2 and 3mm.
3. Diopter compensation
The focus of the microscope is calibrated according to the emmetropia.
If the user is ametropic, he should adjust the eyepiece diopter.
Adjustment should be performed as follows:
• Rotate the diopter adjustment ring (19) counter clockwise until it stops.
• Rotate the ring clockwise until a sharp slit image appears on the focusing
test rod.
• Adjust the other eyepiece using the same procedure.
• Record the diopter value on each eyepiece for future reference.

4. Pupillary distance adjustment
Separate the prism boxes of the microscope with both hands to adjust the
pupillary distance until both eyes can stereoscopically see the same image
on the focusing test rod.
3.2 Patient position and xation target
1. Positioning the patient’s head
Have the patient place his chin on the chin-rest (17) and the forehead against
the forehead belt (24). Adjust the chin-rest elevation adjustment knob (12)
below the chin-rest until the patient’s canthus aligns with the horizontal
mark (23).

2. Use of the xation target
• Direct the patient to look at the xation target (30) with the eye not to be
examined. To change the xation position, move the lamp bar and curved
lever around the headrest.
• The xation target with diopter compensation supplies a dot and concentric
circles target. Slide the knob to adjust the diopter compensation from – 15D
to + 10 D.
