Installation  

2.1  Installation of the binocular viewing head 

1)    Loosen the set screw on the top of the stand and remove the plastic cover on the top. 
2)    Remove the cap on the dovetail of the binocular viewing head. 
3)  Seat the dovetail of viewing head into the socket on the top of the stand and tighten 

the set 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 the light filter 

1)  Swing out the filter holder which is located underneath the condenser. 

2)

  Insert the light filter into the holder, swing the holder back in.
