c. Unscrew the locking screws, that also center the condenser (Fig. 2).
d. Insert the condenser in the support, so that the slot on the collar lines up with the positioning
pivot. (Fig. 3)
e. Tighten the locking screws and centralise, until well supported and turn the focusing knob of
the condenser until it is in its highest position.
B. Specimen holder mechanism (6): Turn the coarse focus knob (16) until the stage (8) reaches its
lowest position. Unscrew the two locking screws (Fig. 1) of the specimen holder mechanism. Place
the mechanism on the stage with the moveable finger pointing upwards (4) so the holes on the
mechanism line up with the locking screws. Tighten locking screws firmly.
C. Objectives (5): Ensure that the revolving nosepiece (3) is well positioned: i.e. that it does not revolve
freely, but rotates until a "click" is heard, showing that it is secure in place. Place objectives, starting
with the lowest magnification 4X in any of the holes in the revolving nosepiece. Next, place that of
the second lowest magnification 10X in the hole alongside, and so forth: the 40X objective, and
finally the 100X objective can be placed.
D. Head (12): Loosen the knurled locking screw on the head (14) and remove the protective cover on
the collar where the head is placed. Insert the head, until it is well supported on the stand (15).
Although the head can be placed in any position, we recommend for your comfort that the eyepiece
tubes (13) face forward on the microscope. Firmly re-tighten the knurled locking screw.
E. Eyepieces (1): Remove the protective covers on the
eyepiece tubes (13). Gently place the eyepieces in
the tubes without touching the lens surface.
F. Filter: Place the blue filter on the illuminator (19).
Make sure that the filter is well positioned.
G. Power cable: Insert the power cable in the connector
situated in the lower back part of the microscope
(Fig.4).
Warning: Before connecting the microscope to a power
source, make sure that the voltage coincides with that of the
microscope.
