5.7 this equipment no electromagnetic(Eye surgical microscope, Eye operation microscope,Eye surgery microscope,Eye Operating microscope), compatibility special requirements, portable and mobile RF communication equipment had no effect on this equipment. This equipment without source and electrostatic put power supply, this system for attachment within the increase and change will not lead to the increase of the launching equipment and immunity to reduce. The equipment should not and other equipment close or layers use, if you must close or layers use, should be observed verification in the use of the configuration can be normal operation (Eye surgical microscope, Eye operation microscope, Eye surgery microscope, Eye Operating microscope),. Three, installation 
1, open the packing container, check whether conform to physical and packing list. 
2, first will stand for good, will microscope(Eye surgical microscope, Eye operation microscope, Eye surgery microscope,Eye Operating microscope), lens (the Lord, deputy microscope) take out, it will be on the left a shaft insertion bending plate of the bottom of hole, and the handwheel binding, again will screw admiral shaft and bending plate binding, and the last in the after electrify check each function is normal use, such as no problems can be pushed into the operating (Eye surgical microscope, Eye operation microscope,Eye surgery microscope, Eye  Operating microscope),room to use. 
　

Four, method of use 
(1), in the surgery microscope (Eye surgical microscope, Eye operation microscope,Eye surgery microscope,Eye Operating microscope), after the installation, push them to the right position surgery, on the base of the two brake, lock instrument, in case microscope (Eye surgery microscope,Eye surgical microscope, Eye operation microscope,Eye Operating microscope),in surgery about. If you want to loosen, please tread down locking lever next to the pedal, the locking lever will advance pop-up, thus loosen instrument, this instrument can move freely. 
(2), switch on the power, open frame on the power switch. 
(3), loosen the frame of all a tight the handwheel (see chart 1), mobile lens to surgery surface(Eye surgery microscope,Eye surgical microscope, Eye operation microscope,Eye Operating microscope), (observation surface) above (or front) work focal length place (as the lens focal length decide) until the eyepiece can see the observation (Eye surgery microscope,Eye surgical microscope, Eye operation microscope,Eye Operating microscope), surface so far, lock on the frame of the handwheel. 
(4) and adjust the master with the hand lens of the eye from the size (figure 1, 8), to suit your distance. 
(5), regulating drum become times the handwheel (figure 1, 6), to the over-error of 2.5 (the largest magnification). 
(6), by foot pedal control lens micro lifting device, until see things surface. 
(7), may be around eyes (Eye surgery microscope, Eye surgical microscope, Eye operation microscope,Eye Operating microscope), vision not consistent, the eyepiece of about objective image definition is differ, right now but screwing in or spin out side of the eyepiece. 
Note: the left ocular diopter position and distance size on everyone basic is fixed, adjusted the is not allowed to adjustment, such as surgery surface(Eye surgery microscope,Eye surgical microscope, Eye operation microscope,Eye Operating microscope), does not clear phenomenon, can adjust working distance. (FIG. 5, 13) 
(8), 6 x assistant mirror: binocular assistant mirror and primary mirror into 90 DHS position, according to need to turn to the right or left of the primary mirror, as long as assistant mirror turn to the left or right position, and the main mirror into 90 DHS postures, adjust good visibility and distance were observed. 
(9), in the surgeon clear observation, assistant mirror observer can't see clearly like, and the surgeon (Eye surgery microscope, Eye surgical microscope, Eye operation microscope, Eye Operating microscope), is different, can adjust the ocular diopter, until clear so far. In the process of operation assistant mirror users without the consent of the the surgeon is can't literally adjust the working distance. 
(11), the choose and buy a (teach mirror, camera, camera device) use. 
(1), loosen 45 º eyepiece group at the bottom of a screw, take off the eyepiece group. 
(2), optical splitter inserted his lens, location is good, tighten the monochrometer a screw. 
(3), will eyepiece group insert optical splitter, location is good, tighten the eyepiece group a screw. 
(4), will teach mirror insert monochrometer (Eye surgery microscope,Eye surgical microscope, Eye operation microscope,Eye Operating microscope),interface (or so all can), optical splitter another side interface insert camera or camera interface, would connect the handwheel tightening, and then put the camera or CCD camera. 
(5), and CCD camera with signal wire and monitor (Eye surgery microscope,Eye surgical microscope, Eye operation microscope,Eye Operating microscope),and video equipment connection, can be realized in the process of operation SheLuXiang. 
(12), after using it, you should turn off light switch, then turn off the power switch. 
(13), in lamp: loosen bearing arm side department of the four screws (figure 1, 12), upward force pull out, can change the light bulbs, in good again after the original direction insert, screw on screw can. 
Five, maintenance and matters need attention 
(a) maintenance 
1, use and storage instrument place (generally refers to the operating (Eye surgery microscope, Eye surgical microscope, Eye operation microscope,Eye Operating microscope), room), should be kept clean, pay attention to dust, moistureproof, acid and alkali resistant, etc have corrosion volatile matter qualitative erosion. Use after application dust shroud live. 
2, special attention should be paid to keep the optical lens clean, fingers are not allowed to touch the optical (Eye surgery microscope,Eye surgical microscope, Eye operation microscope, Eye Operating microscope),lens surface. If the lens surface dust, usable and clean brush or brush wiped the, also can use a handkerchief to wipe gently. If not careful hand met or oil pollution, usable cotton wool with a small amount of ethyl ether ethanol mixture (ethanol 30% ethyl ether 70%) is brushed try, wipe try don't let the mixture into the lens inside. In order to avoid lens degumming or mildew. 
3, optical (Eye surgery microscope, Eye surgical microscope, Eye operation microscope, Eye Operating microscope),fiber is made of many glass composition, unfavorable had large bending force, need bending, curve radian but small (90 ° above), in order to avoid broken, influence through light, deposit should bend coil. 
(2) the matters needing attention (Eye surgery microscope,Eye surgical microscope, Eye operation microscope,Eye Operating microscope),
1, this instrument is Ⅰ class B equipment, request supply network power supply (220 v ± 22 v, 50 hz ± 1 hz) has a good grounding line, and when using please be checked, lest cause security risk. Instrument maximum input power 220 va. 
2, when replacing the fuse please close instrument power switch, unplug the power plug, change the specifications (Eye surgery microscope,Eye surgical microscope, Eye operation microscope,Eye Operating microscope),of the fuse tube, in case produce security risk. 
3, in the operation such as a bulb is damaged, it should be timely enable spare lamp lighting, change bulb must be in stop 30 minutes after tight, in order to avoid high temperature scald. 
4, instrument on the various handwheel when use must be binding, in order to avoid accident. On the frame regulating balance force size the handwheel at the balance arm after adjustment is not active. 
5, the instrument attached electric schematic diagram for reference only maintenance, are subject to change without prior notice.
