ENSURED.
10. Install the new optical element. Incorrect positioning is impossible because the optical element is mechanically
coded. Carefully tighten the two Torx screws and do not over
-
tighten. (Tightening torque of approximately 0.35 Nm).
11. Reinstall the cover to the SZL control unit and tighten the four Torx screws. (Tightening torque of approximately
0.5 Nm). Take care not to trap the cable guide for the windshield wiper switch.
8. Unscrew the four T9 Torx screws of the SZL
housing. Lift open the cover by gently prying it out at
position (1) (using a screwdriver).
9. Unscrew the two T6 Torx screws to remove the
optical element (1) from the board.
Important:
l
Touch nothing other than the optical element.
l
Under no circumstances should the SZL or
optic disk be cleaned or wiped in any way. A
visible haze on the optic disk has no negative
effect on the operation of the SZL.
12. Affix the "OK" label near the part number label
position (2).
13. Reinstall the rotary coupler (slip ring)
Note for correct installation:
Ring (1) must be positioned in the retainer (2) in such
a way that opening (3) for the driving pin (of the rotary
coupler) is at arrow position (4).
