2.3 Checking procedure after assembling.
1. Power plug
• This instrument supplies a 3-wire cable. Please select a proper power socket
as matched.
• Ensured that the instrument is grounded well.
Important Matters
Please use the special cable supplied with this instrument.
2. The power box and the illumination part
• When the main power switch (8) of the power box is placed at “I” it turns
on, and “O” for turn off. The main power switch should be set at the “O”
position before connecting the input cable with the power socket.

• Turn on the main power switch, and the pilot lamp (9) will be lighted. Open
the slit width control knob (12) to examine the illumination.
• Press the brightness control switch (7) respectively at two positions and
the brightness should be changed according.
• Check the fixation target device to confirm it is lighting.
• Check it all the movable parts such as aperture and slit height control knob
(15), filter selection lever (16), and magnification changer lever (13) etc. could
be operated freely.
• After examining, turn off the main power ad cover the instrument with the
dust cover (N).
3. Operation
3.1 Diopter compensation and pupil distance adjustment.
1. Use of the focusing text rod (M) The rod is supplied as one of standard
accesories for confirming the microscopes is adjusted correctly.
Insert it into the main shaft hole with the flat surface.

Important Matters
After adjusting, remember to take out the rod and insert the protection cap.

2. Brightness adjustment
Switch on the main power switch and set the brighttness control switch (7)
at “N” position. Turn the slit width control knob (12) to make the slit width
to be 2-3mm.
3. Diopter compensation
The focus of the microscope is calibrated according to the emmetropia.
If the user is an ametropia, he or she should adjust the eyepiece diopter.
Suggest adjusting the diopter as following procedures.
• First, rotate the diopter adjustment ring (19) counter clockwise down to end.
• Second, rotate the ring clockwise untila sharp slit image appears on the
focusing text rod.
• Adjust another eyepieces as the same procedure.
• Racord the diopter value on each eyepiece for future reference.
4. Pupil distance adjustment
Separate the prism box of the microscope with both hands to adjust the
P.D. until both eyes could see the same image on the focusing test rod
through the eyespieces, and at the same time a stereo vision will be obtained.

3.2 Patient position and fixation target.
1. Positining the patient´s head
Have the patient place his chin on the chin-rest (23) and the forehead against
the forehead belt (20). Adjust the chin-rest elevation adjustment knob (24)
below the chin-rest until the patient´s canthus aligns with the horizontal
mark (22).
