If the laser spot is not in the center of the third mirror, you will need to adjust the angle of the
second mirror using the knobs behind it (Fig. 4–6). These are similar to the knobs behind the
first mirror described in Step 3 above and work identically.

(6) Test the alignment of the second and third mirrors when distant
When the second and third mirrors are well-aligned in Position 1, slowly and gently move the third
mirror along the Y-axis guide rail until it is in Position 2 (Fig. 4–7) far away from the second
mirror. Push the Test Switch button to activate the laser and produce a second spot on the tape on
the third mirror.
