Operation
Each microscope is supplied with 3 rechargeable AA batteries (with an expected life of approximately 500 charges).
To fully charge the LED illumination system, you must plug the adaptor/recharger into both the microscope and an electrical outlet and charge for 5 hours.
When batteries are fully charged, turn the illuminator switch to ON.
Focusing
Turn the coarse adjustment knob counterclockwise to lower the stage. Place a specimen slide on the center of the stage. Using the 4X objective, bring the specimen into focus using the coarse and fine controls. Different objectives can be brought into view by revolving the nosepiece and using the fine adjustment knob because the objectives are parfocal. Each scope is supplied with either a disc or iris diaphragm. Adjust the light by opening or closing the iris diaphragm or by turning the disc diaphragm. Adjust the diaphragm to the smallest size allowable for a clear, sharp image of the specimen.
Cleaning the Microscope
Accumulated dirt on the metal surface should be cleaned with a damp cloth. More persistent dirt should be removed using a mild soap solution. The outer surface of the optics should be inspected and cleaned periodically using compressed air. If dirt remains on the optical surfaces, use a soft cloth or cotton swab dampened with a lens cleaning solution. Optical lenses should always be cleaned in a circular motion. A small amount of absorbent cotton wound on the end of a tapered stick makes for a useful tool for cleaning recessed optical surfaces. Avoid using an excessive amount of solvents as this may cause problems with cemented optics or the flowing solvent may pick up grease from the mounts, making cleaning more difficult.
