Due to the delicate nature of the optics housed within the DE3200 and DE3200-S2, the microscope must be shipped in a partly un-assembled state to ensure safe delivery. 1. Unwrap the modular focus base and vertical illuminator. 2. Remove the dust cover from the back of the vertical illuminator and the front of the focus base. 3. Using a 3mm wrench, mount the dovetail of the vertical illuminator to the modular focus base. DO NOT overtighten the screw as it could crack or damage the mount. Make sure that the vertical illuminator is mounted vertically on the focus base. You can check this by looking at the space between the illuminator and the focus base for clearance.
