2. Refer to 8-9. While monitoring the end surface of the optical fiber through the
fiberscope, adjust the X - Y axes adjustment screw so that the guide beam comes

right.
3. Tighten the lock nut and the X - Y axes adjustment screw. Look
into the fiberscope and verify that the direct guide laser beam is
located at the center of the fiber end face.
