Look into either mirror from a side angle at a minimum of 2 ft (61 cm) from the module.
Use the rear and front sights in the same way as you use sights when aiming a gun.
Rotate the transmitter's optical module left or right until you see the aiming light image
(or receiver's image, if aiming light is not used) in the mirror. The optical module points
at objects seen in the mirror when the front bore sight is in the center of the rear bore
sights as indicated in the following figure.

If the optical module is initially aimed too high or too low, adjust the Vertical Fine Tuning
adjustment Allen screw (with the supplied Allen wrench) slightly up or down until you see
the image.
