1. Eyepiece: Where you look to view the specimen.
2. Adjustable Head: Allows for comfortable viewing angles.
3. Locking Screw: Secures the eyepiece or other attachments.
4. Nosepiece: Revolving turret holding the objective lenses.
5. Objective Lenses: Provide primary magnification (4x, 10x, 40x).
6. Top LED: Illuminates opaque specimens from above.
7. Stage: Platform where the specimen slide is placed.
8. Diaphragm: Controls the amount of light passing through the specimen.
9. Bottom LED: Illuminates transparent specimens from below.
10. Coarse Focus Knob: For large adjustments to focus.
11. Fine Focus Knob: For small, precise adjustments to focus.
12. Power Input: Connection point for the power adapter.
13. LED Power Switch: Turns the illumination system on/off.
14. LED Brightness Switch: Adjusts the intensity of the LED lights.
15. Base: Provides stability for the microscope.

5. Setup

5.1 Initial Assembly

1. Carefully remove all components from the packaging.
2. Place the microscope base on a stable, flat surface.
3. Insert the WF25x eyepiece into the top of the monocular head. If using the 2x optical lens, insert it into the eyepiece tube first, then insert the WF25x eyepiece into the 2x optical lens.
4. Ensure the objective lenses (4x, 10x, 40x) are securely screwed into the revolving nosepiece.
5. Connect the power adapter to the power input on the microscope base and then to a wall outlet.

5.2 Adjusting the Monocular Head

The monocular head can be rotated 360 degrees for comfortable viewing and sharing. Gently rotate the head to your desired position. The 45° inclined optical tube helps reduce eye and neck strain during prolonged observation.

6. Operating Instructions

6.1 Powering On and Illumination

1. Ensure the microscope is plugged in.
2. Flip the LED Power Switch to turn on the illumination.
3. Adjust the LED Brightness Switch to achieve desired light intensity.
4. For transparent specimens, use the bottom LED. For opaque specimens, use the top LED. The microscope supports simultaneous upper and lower LED illumination.
5. Rotate the disc diaphragm located beneath the stage to control the amount of light reaching the specimen and improve contrast.

6.2 Placing a Specimen

1. Rotate the nosepiece to select the lowest power objective (4x).
2. Place a prepared slide onto the stage, securing it with the stage clips.
3. Center the specimen area you wish to observe over the opening in the stage.

6.3 Focusing

1. While looking through the eyepiece, slowly turn the Coarse Focus Knob to bring the specimen into approximate focus.
2. Once the image is roughly clear, use the Fine Focus Knob for precise adjustments to achieve a sharp, detailed image.

6.4 Changing Magnification

The microscope offers six magnification levels: 100X, 250X, 1000X, 200X, 500X, 2000X, achieved by combining the WF25x eyepiece (with or without the 2x optical lens) and the 4x, 10x, and 40x achromatic objectives.

1. To increase magnification, rotate the nosepiece to select a higher power objective (e.g., from 4x to 10x).
2. Make minor adjustments with the Fine Focus Knob to regain clarity.
3. For maximum magnification, ensure the 2x optical lens is inserted before the WF25x eyepiece and use the 40x objective.

6.5 Using the Phone Adapter

The included phone adapter allows you to capture images or videos of your observations.

1. Attach your smartphone to the adapter.
2. Secure the adapter with the phone to the eyepiece.
3. Open your phone's camera app and adjust the position until the microscope's field of view is centered on your screen.
4. Use the microscope's focus knobs to fine-tune the image on your phone screen.

7. Maintenance

7.1 Cleaning

• Always unplug the microscope before cleaning.
• Use a soft, lint-free cloth to clean the exterior surfaces.
• For optical components (eyepieces, objectives), use a specialized lens cleaning solution and lens paper. Do not use abrasive materials or harsh chemicals.
• Remove dust from lenses with a blower brush before wiping.

7.2 Storage

• Store the microscope in a clean, dry, and dust-free environment.
• Use the provided eyepiece cover to protect the eyepiece from dust.
• Rotate the nosepiece so the lowest power objective (4x) is in position before storing.
• Lower the stage to its lowest position to prevent damage to the objectives.
• If storing for an extended period, place the microscope in its carrying bag.
