USING THE REINVERTER
The ROLS Reinverter does not interfere with the microscope's functions.
IN/OUT INDICATOR
The In/Out Indicator of the ROLS Reinverter visually indicates when the prism is
introduced or removed from the optical pathway.
MAGNETIC LATCHING HANDLES
The Magnetic Latching Handles of the ROLS unit have been designed to be easily
removed, adjusted and sterilized by autoclaving or other methods.
Adjustment
Each handle may be independently adjusted to any angle by:
1. Pulling the handle from the unit, rotating it to the desired angle, and
then reinstalling the handle on the splined end.
2. Verify the edge of the handle and the edge of the In/Out Indicator are
seated flush together. If necessary, adjust each handle position slightly
until you hear a "click" sound, which will indicate the handle is in place.
Operation
When using a plano/concave lens or when the operating microscope is used in
other applications, use the reinverter in the Out position. To remove the prism from
the optical pathway, rotate either handle 60° until the In/Out Indicator reads Out.
When using any of the vitrectomy contact lenses, use the reinverter in the In posi-
