38 Powering up the System

3 Install the Telescope Assembly (12) on the detector/source front. Fasten

the Telescope with Fastening Screws (13).

4 Crude Alignment

a Use ¼” Allen screw driver for all alignment screws

b Loosen screws 5, 6

c Approximately aim the source horizontally toward the detector

d Tighten screw 6

e Loosen screws 3, 4

f Approximately aim the source vertically toward the detector

g Tighten screw 3

5 Repeat step 4 for the Detector

6 Fine Alignment

a Aim the Source to the Detector within horizontal axis using screws

7. Aim the cross to the detector or source center of the front

window (see figure 1 & 2 item 8).

b Tighten screw 5

c Aim within the vertical axis using screw 8

d Tighten screw 4

e Make sure the telescope cross is pointing to the detector and
