Comparing and Installing Lenses

Both the New and Old Scope-On-A-Rope education kits come with three lenses: 1X, 30X, and
200X. Refer to the table below for general information on these lenses. Detailed instructions for
using each lens are included in the following pages of this section.

To remove a lens, rotate it counterclockwise until the small index marks on the lens and the
camera body line up. The lens should then be easily removed. To place a lens on, you must
reverse the process. First, line up the small index marks on the lens and the camera body. Do
not force the lens onto the scope! There are several contact points that need to meet up just
right for the lens to function properly. Once the lens is in place, twist it clockwise until it firmly
clicks into place. You should hear a satisfying "snap" when it's on correctly.
