1. Purpose and features
The YDJ-II LED Colposcope are precise optical instruments designed specially for the gynecologic
examination and diagnosis in hospital environment. Due to the 5-step magnification of the instrument, the
pathological changes in the vagina, which is impossibly viewed with naked eyes, can be clearly seen with the
instrument. Therefore, the correctness of a diagnosis is enhanced significantly. Examination can be performed
with vagina cell applied plate and pathological slice.
The YDJ-II LED Colposcope are featured for sharp image, wide field of view, uniform illumination,
adjustable brightness and easy operation. They are the essential instruments for gynecologic examination.

4. Use of equipment
4.1 Necessary working condition
Please make sure the following items, then enter into the next operation:
■ Please check whether the main voltage and frequency comply with what required by the equipment.
Input voltage is AC100-240V and frequency is 50-60Hz.
■ Please use the power adapter supplied with this equipment.
■ Please make sure that all mechanical parts concerning security should be assembled in the right way.
4.2 Precautions of using
■ Please never watch the light source directly through the objective.
■ Please do not cover the heat elimination hole of power supply box and LED.
■ Please pay more attention to the caution on the equipment.
4.3 Adjusting the colposcope before using
■ Adjust the working distance of colposcope and pupil distance first.
■ Emmetropia: Adjust the eyepiece to 0 diopter; Operator with glasses: Adjust the eyepiece to 0 diopter;
Ametropia (who know their refractive powers and perform surgery without wearing their glasses):adjust the
eyepiece to his/her eyesight.
■ Ametropia (who do not know their refractive powers and perform surgery without wearing their glasses ):
adjust both eyepieces to +5D, take out the binocular heads with eyepieces from the microscope and observe
the distant object, just like using a telescope. Then rotate the diopter adjustment hoop of one eyepiece until the
image clear. If necessary, please repeat this process for three times. Use the same method to adjust the other
eyepiece. Assemble the binocular heads witheyepieces back to the microscope body.
Caution: It is necessary to make a form if several doctors share an operation microscope. Every doctor's
diopter should be filled into the form and keep the form in a place where all those doctors using the colposcope
will read them.
4.4 Adjusting the CCD adaptor
■ When using CCD adaptor, first see clear image through the binocular head, then turn the fine focusing
ring on CCD adapter until the image in the screen is seen clearly. If the direction of image viewed with CCD is
different from that viewed with the binocular observation unit, screw out the locking screw(15, Fig.2) on the
adapter and turn the camera till the image direction is the same as the image viewed with the binocular
observation unit, then tighten this screw(15, Fig.2).
4.5 Inspection before using

5. Maintenance
5.1. Cleaning and disinfection
Caution: The dirt on the lens must be cleaned immediately after using. It will be hard to clean when the dirt
air-dried.
5.1.1 Cleaning the surface of equipment
The outer surface of the equipment can be cleaned with wet cloth. The remaining stains can be cleaned off
with the mixture of 50% distilled water. Do not wipe with any corrosive detergent lest that the surface should
be damaged.
5.1.2 Cleaning the surface of optical lens
To prevent the dust stained on the lens, never expose the optical lens to air without objective, eyepiece tube
and eyepiece. Please use the dust cover after using.
Cleaning the surface of optical lens: To clean the dirt on lens, such like bloodstain, please use the special paper
or absorbent cotton with little bit distilled water and wash, the remaining stains can be cleaned off with the
mixture of 50% Ethanol and 50% aether. If there is dust stained on the lens, blow them with a blow ball or
brush them with a dust pen. Do not wipe with any corrosive detergent lest that the lens should be damaged.
