2. Turn the fixture over and remove the thumb screw holding the cover in
place.
3. Slide the fixture cover open.
4. Turn the focus knob clockwise as far as it will go. This will move the
lens module towards the front of the fixture, giving enough space to
remove the lens module.
5. The lens module has a
bayonet-type fitting.
Working through the
front aperture of the
fixture, loosen – but do
not remove – the three
2mm Allen bolts
around the lens.
6. Working inside the fixture, grasp the lens module and twist it
counterclockwise so that it is released from the mounting screws. Lift
the lens module out of the fixture.
