4. Procedure
Subtask 23-73-64-720-050-A ** ON A/C NOT FOR ALL

A. Do this adjustment test.

ACTION	RESULT
1.On the PSIU 2040VU and 2041VU:	On the related reading light:
push the related pushbutton switch to on.	the reading light beam will fall on the related passenger seat.
NOTE: Do not adjust the angle of the beam light more than 20 degrees in any direction. 2.On the PSIU 2040VU and 2041VU: adjust the beam light with the adjusting device.	On the related reading light: the light points fall to the middle of the leading edge at the related seat.
3.On the PSIU 2040VU and 2041VU:	On the related reading light:
push the related pushbutton switch to off.	the reading light goes off.
4.Do again this procedure on all reading lights.

Subtask 23-73-64-720-050-B ** ON A/C NOT FOR ALL

A. Do this adjustment test.

NOTE: The subsequent adjustment test gives the procedure for one reading light. The procedure is the same for all reading lights.

ACTION	RESULT
1.On one PSU:	On the related reading light:
push the related pushbutton switch to the ON position.	the reading light beam falls on the related passenger seat and/ or the folding table.
NOTE: Do not adjust the angle of the light beam more than 20 degrees in any direction.
adjust the light beam with the adjusting device.	At the passenger seats:
	the folding table is fully illuminated. NOTE: The light beam has its focus on the surface of folding table. This point is directly in front of the passenger and approx. 25% of the distance from the aft table edge to its forward edge. Adjustment of the Reading Light ** ON A/C NOT FOR ALL
	At the attendant seats:
	the light beam points to the middle of the leading edge of the related seat.
push the related pushbutton switch to the OFF position.	the reading light goes off.
2.Do this adjustment procedure again for all reading lights.	all light beams point to the middle of the leading edge of the related seat.
