1. Use ONLY the fine adjustment knob to focus on high power. NEVER USE THE COARSE FOCUS KNOB ON HIGH POWER! The high power lens should be very close to your slide when in proper focus. If you turn the coarse adjustment knob while on high power, the objective could easily break your slide.
2. The microscope arm connects the eyepiece tube to the base. This is the part you should hold when transporting a microscope.
3. The coarse adjustment knob located on the arm of the microscope moves the stage up and down to bring the specimen into focus.
4. Hold the microscope with one hand around the arm of the device, and the other hand under the base. This is the most secure way to hold and walk with the microscope. Avoid touching the lenses of the microscope. The oil and dirt on your fingers can scratch the glass.
