Operating the Microscope

1. Turn On Illumination: Locate the LED illumination switch at the base of the microscope and turn it on. Adjust the brightness if a dimmer is present.
2. Focusing: While looking through the eyepiece, slowly turn the coarse focus knob (larger knob on the side) to bring the specimen into approximate focus. Then, use the fine focus knob (smaller knob, if present) for sharper detail.

4. Using the Smartphone Adapter:
   • Attach the smartphone adapter to the eyepiece.
   • Secure your smartphone in the adapter, aligning the phone's camera with the eyepiece.
   • Open your phone's camera app to view and capture images or videos of your specimen.
