10 Rotate the COLLECTOR TILT SCREW counterclockwise and record the number of
rotations until the LEDs change from amber to red, green or no color.
Note
The number of rotations is approximately 70 - 100.
11 To obtain the center position of the COLLECTOR AY, do the following formula:
number of rotations from Step 10 ÷ 2
example: 74 rotations ÷ 2 = 37

“Scan Line Bow Magnitude” ÷ 40 = number of rotations for “Scan Line Bow”
Important
If the number of rotations for “Scan Line Bow” is:
• positive - you must add the number of rotations to the center position determined in
Step 11
• negative - you must subtract the number of rotations from the center position determined
in Step 11
16 Determine the new number of rotations for the COLLECTOR TILT SCREW, see the
examples:
Example 1:
• number of rotations = 74 ÷ 2 = 37
• number of rotations for “Scan Line Bow Magnitude” = -120 ÷ 40 = -3
• new number of rotations = 37 - 3 = 34 rotations
Example 2:
If you rotated the COLLECTOR TILT SCREW 74 rotations and the“Scan Line Bow
Magnitude” is -120 um, rotate the COLLECTOR TILT SCREW clockwise until the
LEDs illuminate amber then continue clockwise for 34 rotations to center the
“scanline” in the COLLECTOR.
17 Rotate the COLLECTOR TILT SCREW clockwise the new number of rotations obtained
in Step 16.
