Receiver Alignment:

Next, remove the paper and clear the light path of all obstacles.

Observe the “LIGHT LEVEL” on the display. The alignment

screws on the Receiver are used to optimize the light level as

observed on the Display. Adjust the receiver alignment screws

until the light level reaches its most negative number. This last

step directs the optical beam through the optical components of

the Receiver to the Detector. Be sure to tighten all nuts on

lamp and receiver after alignment.
