PARTS LIST
OPERATION
1. Remove all components from package. Identify all parts before
assembling instrument.
2. Attach 4x, 10x and 40x objectives by screwing into revolving
turret. Tighten and secure to maximum finger pressure only.
3. Place the specimen on the stage and secure with spring clips.
NOTE: The cover glass must face upward (the thinner glass is
the cover glass), otherwise when the 40x objective is used the
specimen cannot be observed. Observation is best when the
thickness of the cover glass is 0.1-1.1mm and the cover glass
is 0.17mm.
4. Plug power cord into an electrical outlet. Turn microscope
lamp ON.
5. Observe the specimen using the lowest magnification objective
first. The 10x objective provides a larger field of view making it
easier to search the specimen.
