How To Use The 50X Lens - scope LSU VL-7EX II User Manual

To remove a lens, press the lens release button and, while
holding it, rotate the lens 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,
simply 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 seated properly, twist it clockwise until it
firmly clicks into place–you do not need to press the button.
You should hear a "snap" when it's on correctly.

How to Use the 50X Lens

When first using the L2, it's best to begin with the 50X lens; it's the lens that comes with all kits.
Just remember some basic rules to share with your students:
Never immerse the lens tip in a liquid
•
Never touch anyone's eye or mouth with the lens tip
•
Never point the lens at someone's eye
•
Take proper precautions to avoid spread of infection
•
After setting up your scope, make sure the power is
on both the scope and the display (TV, projector,
etc.). If there are no lights shining in your lens,
check to be sure that the power is set to AUTO and
the light switch is on "A". To get a focused image on
the screen, you must touch the lens tip to the item
you wish to view. It's that simple! Since the actual
lens is inside the plastic housing, you cannot
damage it by touching objects to the tip. Just
remember the basic rules listed above.
Note: holding the tip of the lens flat against the
object will give you the best image.
