Installation  

1.1  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. 

4) Tighten the thumb screw. Do not release the head from your hand grip until you are 

sure the head is installed securely.   

1.2  Installation of the eyepieces   

1) Remove the protective caps from the eyepiece tubes.   

2) Insert the eyepieces into the eyepiece tubes.     

1.3  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. 

1.4  Installation of the glass filter 

1) Swing out the filter holder under the condenser.   

2) Insert the filter into the holder, swing the holder back in.   

1.5  Replacing the fuse 

1) Turn off the power and disconnect the power cord. 

2) Turn the fuse holder counter-clockwise to take it off. 

3) Insert new fuse, and then turn it back on clockwise. 

Caution: 

The fuse is located at the bottom of the base. 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.

 

1.6  Installing (or changing) the halogen bulb 

1) Turn the power off and disconnect the power cord. Allow some time to cool down the 

lamp.  

2) Open the cover on the bottom of the base by loosening the thumb screw.   

3) Take out the dead bulb and insert the new bulb. Be sure the pins on the bulb are 

completely inserted into the lamp socket.
