E. use of the 3X or 5X Magnifier Lens Assembly.
The 3X or 5X
magnifier lens assembly can be threaded directly into the 1X objec-
tive lens, with the light interference filter (LIF) and sacrificial window
removed. It can also be threaded into the focus ring adapter and
slipped on over the end of the objective lens with the LIF installed.
NOTE
The Neck cord can be used to tether the magnifier to your person to
prevent losing the lens if it is dropped. To use the Neck cord, tie the
end without the clip tightly around the magnifier and attach the clip
to a buttonhole, belt loop or other convenient point.
