Installation
2.1 Installation of the binocular viewing head
1) Loosen the thumb screw on the head of the body and remove the plastic cover on
the top
2) Remove the cap on the dovetail of the binocular viewing head
3) Insert the binocular viewing head into the head of the body; ensure that the dovetail
is completely seated into the socket; tighten the thumb screw.
Caution
: Do not release the head from your hand grip until you are sure the head is
installed securely.
2.2 Installation of the eyepieces
1) Remove the protective caps from the eyepiece tubes.
2) Insert the eyepieces into the eyepiece tubes.
2.3 Installation of the objectives
1) Adjust the coarse focus knob until the mechanical stage is at its lowest position.
2) Install the 4x objective into the nosepiece. Then in a clock-wise direction, rotate the
nosepiece and install each succeeding higher magnification objective.
Note:
Inspect the objectives frequently for dirt or oil; clean if necessary. Use the 10x
objective to initially focus the image of your specimen. When changing the objective
magnification, rotate the objective nosepiece until you hear a “click” sound. This
ensures the objective is centered in the optical light path.
2.4 Installation of filter
1) Swing out the filter holder under the condenser.
2) Insert the filter into the holder, swing the holder in.
2.5 Installing (or changing) the halogen bulb
1) Turn the power off and disconnect the power cord.
2) Allow some time to cool down the lamp.
3) Turn over the microscope on its side; find the bulb compartment at
the bottom.
4) Open the cover of the bulb compartment by loosening the thumb
screw. Take out the dead bulb and insert the new bulb. Be sure
the pins on the bulb are completely inserted into the lamp socket.
You may also loosen the two screws on the cover to adjust the
position of the bulb to get centered and even brightness. Screw the cover on.
Caution:
Before you turn over the microscope, be sure to take the eyepieces off and be
certain that the head is securely locked by the thumb screw.

1) Turn off the power and disconnect the power cord.
2) Turn over the microscope on its side; find the fuse at the bottom of the base.
