2.2.1. Mounting binocular viewing head (Fig.1, Fig.2) 1. Rotate the objective ① into the objective mount thread on the lower end of the zoom body. ②, as ③ in fig.2. 2. Aligning the positioning pin of the zoom body ③ to the positioning groove on the binocular viewing head ④, insert the dovetail mount at the bottom of the viewing head into the mounting port on the zoom body ③, and tighten the viewing head clamping screw ⑤ with provided hexagonal driver. Fig.1 ② ① ⑤ ④ ③ Fig.2 Positioning Pin Mounting Port Note: Working Environment Requirement： 1. Ambient temperature: 5°C to 40°C. (41°F to 104°F), Maximum R.H: 85%. 2. High Temperature will result in a mildewing, dew and even ruinous instrument. 3. Avoid placing the instrument in a dusty environment. When ending your microscope operation, please cover it with the dust cover. 4. Lay the microscope in a plan and stable position, please.

Loose the clamping bolt ⑦ on the pillar ⑥ and insert the binocular head and zoom body assembly ⑧ into the bracket of the pillar, then screw down the bolt ⑦. 2.2.3. Mounting eyepieces (Fig. 3, Fig. 4, Fig. 5) 1. Remove the eyepiece dust caps ⑨ and gently insert two adjustable eyepieces ⑩ into the eyepiece sleeves until they stops, as in Fig.4. 2. Using the Eye Shades When Wearing Eyeglasses: Use with eye shades in their normal folded-down position. This will prevent eyeglasses from being scratched by the eyepiece as in Fig 5. When Not Wearing Eyeglasses: Extend the folded eyeshades. This makes observation easier by preventing the inverse incidence of light from between the eyepiece and your eyes. 2.2.4. Connecting the power cord (Fig. 6) 1. Turn the main switch ① on “O” (off) state before connecting the power cord. 2. Insert the power plug ② into the power jack of the microscope; make sure the connection is well. 3. Plug the power cord ③ into the power supply receptacle safely. Make sure the connection is well. 2.2.5. Mounting glass stage plate (Fig. 7) If necessary, the original plastic stage plate can be replaced by a glass one.  Both top and bottom illuminators are LEDS.  Permitted power supply voltage: 100V～240V.

 The aperture iris diaphragm adjustment can increase the image contrast and focus depth.  The size of aperture iris diaphragm can be adjusted. Switch the lever to left to open the aperture iris diaphragm; to the right, to close the aperture iris diaphragm. Check the effect during observation.  Do not close the aperture iris diaphragm too much, or it will decrease the resolution and lead to lack of illumination.  Closing the aperture iris diaphragm to the minimum state will result in faintness in field of view. In this case, adjust the aperture iris diaphragm to the half open state.  Closing the aperture iris diaphragm to the minimum state and increase the magnification of the zoom body will result in lack of illumination around circumference of field of view. Fig.8 ① ② Fig.9 Aperture iris diaphragm lever ③ 2.2.6. Mounting aperture iris diaphragm attachment (Fig.8, Fig.9) o Aperture iris diaphragm attachment is optional. 1. Use the provided hexagonal driver to loosen the clamping bolt and remove the binocular viewing head ①. 2. Mounting the aperture iris diaphragm attachment ② to the top end of the zoom body. 3. Mounting the binocular head into the aperture iris diaphragm attachment and tighten the clamping bolt ③.

3. ADJUSTMENT AND OPERATION Fig. 10 ① ⑤ ④ ② ③ Fig. 11 3.1.1. Adjusting interpupillary distance (Fig. 10) Different users have different interpupillary distances. So when users change, do the interpupillary distance adjustment. 3.1.2. Adjusting diopter ring (Fig. 11, Fig. 12) 1. Set the diopter rings of both eyepieces to “0”position. (Do this when users change, because different users have different diopters.) 2. Place an easy-to-observe specimen on the stage plate. 3. Rotate the zoom body knob ③ to the highest magnification 5× (or 6.4×, or 10×), and turn the focusing knob ④ to focus the specimen. 4. Rotate the zoom body knob ③ to the lowest magnification 0.8×, looking only into the left eyepiece, adjust the diopter ring on left eyepiece to focus the specimen. Then do the same thing for the right one. 5. Repeat item 3 and 4 until the specimen image can always focus without any adverse effect of the changes of magnification on the definition of the image. Fig. 11 shows the focusing part of Stereo Microscope NYMCS-360/361; Fig.12 shows the focusing part of Stereo Microscope NYMCS-360. There are coarse focusing knob ⑥ and fine focusing knob ⑦ in this kind of microscope.  The working distance of the objectives listed in standard outfit is all 78mm for these three kinds of stereo microscopes. When 2× objective is chosen, it is necessary to mount the binocular head bracket ⑤ onto the lower position. Remove the clamping bolt with provided hexagonal driver and move the bracket down to the lower position and set it with original bolt (Fig. 11).

Spanner Fig.15 ⑤ ① ② Fig.13 ③ ④ Fig.14 3.2.1. Adjusting the rotation tension of the focus adjustment knob (fig. 13, fig. 14) The tension of the microscope has been adjusted well before delivery. 1. Rotate the focus adjustment knob ① to move the slider ② to a lower place for fear that the zoom body drops down suddenly if the tension is decreased too much. 2. Hold the focus adjustment knobs ① with both hands, stop the left knob and rotate the right knob to increase or decrease the focus knob tension. 3. Brightness adjustment: the right brightness adjustment knob ③ is used to adjust the bottom illumination, and the left brightness adjustment knob ④ is used to adjust the top illumination. 3.2.2. Adjusting tension collar (Fig. 15) 1. For coarse and fine focus stand, if the microscope body falls down by its own weight or the focus obtained by fine focusing is lost immediately, the rotation tension adjustment may be too light. In this case, rotate the tension collar with provided spanner to increase the rotation tension. SAFETY PRECAUTION: 1. After the equipment has been used in an observation of a specimen that is accompanied with a potential of infection, clean the parts coming in contact with the specimen to prevent infection. 2. Moving this microscope is accompanied with the risk of dropping the specimen and causing infections. Be sure to remove the specimen before moving this product. 3. Move the microscope with both hands; one hand catches the arm, and the other hold the base.
