Setting Up Your Microscope

1. Remove the microscope and accessories from the carton and place them on a flat surface.
2. Remove the protective bag from the microscope.
3. Remove the cap from the eyepiece tube.
4. Insert the WF 10x eyepiece into the eyepiece tube.
5. Plug the AC adapter into the socket on the back of the base and connect to a power source. Alternatively, insert three AA batteries into the battery compartment on the base.

Microscope Operation

Viewing a Specimen

1. Place a specimen slide under the stage clips and center the specimen. Note that images will appear upside down and reversed.
2. Focus on the specimen using the focus knob. Be careful not to let the objective lens touch the slide when focusing at higher magnifications.

Focusing and Changing Power (Magnification)

1. Start with the lowest power (4x objective and WF 10x eyepiece).
2. Place the specimen slide on the stage directly under the objective lens.
3. Gradually turn the focus knob until the specimen is in focus.
4. For higher magnification, rotate the nosepiece to select the 10x or 40x objective lens. Refocus as needed.
5. Note: Lower the stage with the focus knob before rotating the objective carriage.

Adjusting the Illumination

Use the illuminator adjustment wheel to increase or decrease illumination. The wheel has three settings (I, II, III) for optimal lighting.

Diaphragm

The disc diaphragm has six aperture openings to adjust the amount of light passing through the specimen, maximizing brightness and contrast.

Care, Maintenance and Warranty

• Remove specimens after use and turn off the power. Unplug the cord if applicable.
• Cover the microscope with the plastic bag or dust cover when not in use.
• Store the microscope in a dry, clean place.
• Avoid direct sunlight to prevent damage to the microscope or eyes.
• Carry the microscope by the arm and support the base. Do not grasp by the focuser knob or head.
• Clean exterior surfaces with a moist cloth. Unplug cords before cleaning.
• Never clean optical surfaces with paper towels; use an air blower or camel hair brush. For fingerprints, use a lens cleaning agent and lens tissue, cleaning in a straight motion.
• Do not disassemble the microscope or clean internal optical surfaces. Contact authorized service for repairs.
• Handle glass slides with care as edges can be sharp.
