4. Setup

1. Unpacking: Carefully remove all components from the packaging. Retain the original packaging for future storage or transport.
2. Placement: Place the microscope on a stable, level surface, away from direct sunlight and heat sources.
3. Eyepiece Installation: Insert the desired eyepieces (WF10X or WF25X) into the eyepiece tubes of the trinocular head.
4. Objective Lens Rotation: Rotate the revolving nosepiece to ensure the 4X objective lens is positioned directly above the stage.
5. Power Connection: Connect the power adapter to the microscope's power input and then to a suitable electrical outlet.
6. Illumination Check: Locate the light switch on the base of the microscope and turn it on to verify the LED illumination is functional.

5. Operating Instructions

5.1 Preparing a Specimen

• Place a prepared slide or your own specimen on a blank slide onto the mechanical stage.
• Secure the slide using the stage clips.
• Use the X-Y axis adjustment knobs to center the specimen under the objective lens.

5.2 Adjusting Magnification

• The microscope features 195 flat-field achromatic objective lenses: 4X, 10X, 40X, and 100X.
• Combined with WF10X and WF25X eyepieces, total magnification ranges from 40X to 5000X.
• To change magnification, rotate the revolving nosepiece to select the desired objective lens. Start with the lowest magnification (4X) for initial viewing.
• For higher magnifications (e.g., 100X), immersion oil may be required for optimal clarity.

5.3 Focusing

• Use the coarse focus knob (larger knob) to bring the specimen into approximate focus.
• Then, use the fine focus knob (smaller knob) for precise focusing and to achieve a sharp image.
• The coaxial design allows for easy and integrated control of both coarse and fine adjustments.

5.4 Illumination Control

• The microscope features an LED illumination system.
• Adjust the light intensity using the brightness adjustment knob located on the base.
• The Abbe condenser allows for easy adjustment of light intensity and aperture for different specimens.

5.5 Trinocular Head Usage

• The trinocular head provides a dedicated port for attaching an electronic eyepiece or microscope camera (camera not included).
• This allows for viewing, broadcasting, recording, and capturing enlarged specimen images on an external display.
• The hinged viewing tube offers binocular viewing with adjustable interpupillary distance (56-74mm) and diopter adjustment for comfortable observation for both adults and children. The head is 30° tilted and 360° rotatable.

6. Maintenance

• Cleaning Lenses: Use a soft brush to remove dust, then gently wipe with lens paper or a microfiber cloth. For stubborn smudges, use a small amount of lens cleaning solution.
• Cleaning Body: Wipe the microscope body with a soft, damp cloth. Avoid harsh chemicals.
• Storage: When not in use, cover the microscope with the provided dust cover and store it in a cool, dry place to prevent dust accumulation and damage.
• Handling: Always carry the microscope by its arm and base. Avoid touching the lenses directly.
