PARTS LIST
OPERATION
1. Remove components from package.  
    identify all parts before assembling. 
2. Tighten the knob on the stand to  
    prevent the elevator from sliding  
    down.
3. Fix the binocular body on the stand  
    with the tightening screw.
4. Check the input voltage to ensure that  
    it conforms to the microscopes   
    requirement.
SELECTING THE ILLUMINATION  
1. Depending on microscope use, select  
    oblique or transmitted illumination. 
2. The Brightness Adjustment knobs  
    change the oblique or transmitted   
    light independently. The transmitted  
    illuminator fluorescent lamp cannot   
    be adjusted.
3. The angle of the oblique lamp can be  
    adjusted to ensure optimum lighting   
    of the sample.

    the sample.
CHANGING THE INTERPUPILLARY 
DISTANCE
1. The distance between the observer's  
    pupils is the interpupillary distance.   
2. To adjust the interpupillary distance  
    rotate the prism caps until both eyes  
    coincide with the image in the   
    eyepiece.
