2. Use the X and Y adjustment screws to maximize the output signal. These adjustments are extremely sensitive. Once the XY maximum is achieved, only very small adjustments are needed.3. Adjust the Z1 position socket head cap screws. Start at any SHCS on the face of the fiberport and make very small adjustments to get a maximum in the output signal.4. Adjust the next two SHCS Z2, Z3 and get a maximum in the output signal. And repeat the step 3, and the Z maximum is achieved.5. After adjusting the SHCS, the signal may be lower that before the adjustment. Re-adjustment of the XY screws in the next step will show the increase in signal power.6. Repeat step 2, 3 to reach an absolute maximum signal.7. Screws the Plunger screw to lock the fiberport.
