I. Assembling the microscope
   The components for the S41-20 microscope are shipped detached for protection. Open the styrofoam packing with care and do not leave any components attached to the packing being removed. Do not discard any of the packing materials until all of the components have been identified. Remove the plastic covers from the microscope's head and the two gooseneck LED lights.

Assemble the stand connector and its supporting pillar on the vertical pillar, tightening the fastening knobs. Attach the working arm to the stand connector, the focus block connector to the microscope head, and then connect the working arm and focus block connector via the focus block fixing knob.
 
Locate the power cord, attach it to the microscope, and then plug it in. Turn on the power switch found on the back of the microscope stand.

II. Using the microscope

    Interpupillary adjustment
    Adjust the two eyepiece tubes until only one circular field can be seen through the two eyepieces. If two separate circles appear, the interpupillary distance is too large; if two overlapping circles appear, the interpupillary distance is too small. The eyepiece tube allows a flexible adjustment of the interpupillary distance between 54 and 76mm.

    Focusing the microscope
    To focus the sample, use the focusing knobs located on both sides of the head holder. By turning these knobs, the microscope can be moved up or down a certain distance. This movement is enabled by a "rack and pinion" mechanism.
 
Using the focusing knob, focus the sample until the image is clear. If the sample cannot be brought into focus within the travel range of the S303/S304 pole arm and stand, adjust the microscope head height along the vertical pillar to a working distance of 230mm from the sample. Remember to tighten the locking screw and support collar after adjusting the height of the microscope
