- Microscope Head Attachment: Mount the binocular microscope head onto the stand pillar. Ensure it is securely fastened using the locking screw.
- Eyepiece Installation: Gently insert the two WF10X eyepieces into the eyepiece tubes of the binocular head.
- Fluorescent Ring Light Attachment: Attach the 8W fluorescent ring light to the objective lens housing. Ensure it is positioned correctly to provide even illumination.
- Power Connection: Connect the power cord of the ring light to a suitable electrical outlet (110V).

3. Operating Instructions
- Power On: Flip the power switch on the ring light to turn on the illumination.
- Specimen Placement: Place your specimen on the stage plate. Use the stage clips to hold it in position if necessary.
- Magnification Adjustment: The microscope offers 10X and 30X magnification. Rotate the objective turret to select the desired magnification. The current magnification (1X or 3X on the objective) combined with the 10X eyepieces provides 10X or 30X total magnification.
- Focusing: While looking through the eyepieces, slowly turn the coarse focus knob (large knob on the side) to bring the specimen into sharp focus.
- Interpupillary Distance Adjustment: Adjust the distance between the two eyepiece tubes to match your eye separation for comfortable viewing.
- Diopter Adjustment: If one eyepiece has a diopter adjustment ring, use it to compensate for differences in vision between your eyes after focusing with the coarse knob.

4. Maintenance
- Cleaning Lenses: Use a soft, lint-free cloth and a specialized lens cleaning solution to clean optical surfaces. Avoid touching lenses with bare fingers.
