Handheld Microscope Users Guide
Follow the safety rules for using the scope: never immerse the lens tip in a liquid; never
•
touch anyone's eye or mouth with the lens tip; and take proper precautions to avoid the
spread of infection (e.g. don't touch mouths, scabs, or open wounds).
Always store the scope with a lens on to prevent dust and/or moisture from accumulating on
•
the camera chip.
Store all pieces in a safe place when not in use, as lenses and other small parts are
•
frequently lost.
Cleaning
When using your scope, the lenses might get dirty, and/or dust might collect on the camera
chip. To clean your scope:
1. With the scope off and unplugged, you can use a dry cloth to wipe any dirt or dust that has
collected on the scope. It is not advisable to use a damp cloth, as water could get inside of
the scope and damage the electronic components.
2. The tip of most lenses cannot be removed, but you may carefully wipe the plastic tip with
disinfectant, if needed. Just be careful not to drip any liquid inside the hole in the lens tip!
(Note: If you have the new or old SOAR, the tip of the 30X lens can be removed for
cleaning.)
3. If you find that your images have the same dark spots no matter what sample is viewed, you
most likely have dust accumulated on the camera's chip. These specks are usually so small
that they are only visible when using the 200X lens. To clean the chip:
a. Remove the lens from the scope so that you can see the green camera chip in the
scope.
b. Get a condensed air canister, such as what is used to clean keyboards (most scope
education kits come with one).
c. Hold the air canister upright and bend the tube to blow air onto the chip. DO NOT TILT
THE CANISTER OR MOISTURE WILL COME OUT AND RUIN YOUR SCOPE!
d. If there are still visible dark spots on the screen, you can LIGHTLY brush off these
particles from the green chip with a cotton swab.
