Precaution Digital usb microscope
Before using The USB Digital Microscope, please ensure that you read and understand the safety precautions described below.
Always ensure that the USB Digital Microscope is operated correctly.
- The Microscope is not waterproof, so keep it dry.
- Do not use it in a humid place like bathrooms. A dry environment will maintain its life to the maximum.
- Use the Microscope only at -5-50.
- Sudden temperature change may form dew inside the Microscope like entering a warm room in cold winter. Put it inside a handbag or plastic bag to slow down temperature changes.
- Do not point the Microscope lens to the sun or strong light for a long time. Powerful light may hurt the light-sensitive electronics.
- Avoid touching the lens.
- The white LEDs which illuminate the Microscope target field are very bright. Do not stare directly into these LEDs as it may damage your eyes.
- The clear plastic distance shell sometimes picks up dirt or toxic material from a microscopically observed surface. Be careful that this doesn’t get in contact with the human skin. Always wash carefully or disinfect as needed.
- Do not unplug the Microscope from the USB port when LEDs are on. This may cause information loss or circuit damage. Please always close MicroCapture Plus and then unplug the Microscope.
