Thank you for purchasing our slit lamp microscope！The following is the description and
specification of our product.
General description
This user manual elaborates on the relevant technical specification and operation notes of our slit
lamp.
Working principle: A beam of light attached to the slit lamp projects to the patients’ eye, which
forms an optical section of the living tissue of the eye, in this way the doctor can finish the
observation and examination.

much dust and with high temperature. Use it in room and simultaneously be careful to
keep it clean and dry.
3. Other medical equipment and devices that must be installed in the same place should
follow the same electromagnetic compatibility principle. If the other device cannot
apply to the same principle, please keep a distance of 3 meters at least between the two
devices. And do not share the same power supply cable with the two devices.
4. Check that all the wires are correctly and firmly connected before using. Ensure that
the instrument is well grounded.
5. Please pay attention to all the ratings of the electrical connecting terminal.
6. Turn off the main power first before replacing the main bulb, flash lamp and fuse.
7. When replacing the power cable, please use the power cable in accordance with the
notes in the instruction manual.
8. Don’t touch the surface of the lens and prism with hand or hard objects.
9. To prevent the instrument from falling down to floor, it should be placed on the floor
where the inclination angle is less than 10°
10. Please deal with the waste disposal produced by the machine following relevant laws and
regulations.
11. Read carefully the safety and other signals on this machine in order to use the product
safely.
