2: Setup and Configuration
2. Remove the front barrel assembly of the Source Four ellipsoidal fixture by loosening the
thumbscrew and the Philips set screw located above and beneath the lens barrel. Rotate the barrel
assembly until it releases from the mounting tabs located in the rear housing assembly.
3. Insert the SeaChanger into the Source Four rear housing assembly by aligning the mounting tabs
into the rear-locking ring of the SeaChanger. You must rotate the rear housing until the Source
Four mounting tabs are captured in the SeaChanger locking ring channels. Tighten the
thumbscrew and Philips set screw to lock the module onto the Source Four fixture.
5. Insert the front barrel assembly onto the front locking ring of the SeaChanger, engaging the barrel
assembly into the locking ring channels.
6. Adjust the front barrel assembly to the desired orientation and tighten the thumbscrew and Philips
set screw to lock the front barrel assembly to the SeaChanger.
7. Mount the unit using safety cable at the mounting location.
Optimizing Performance
Soft Edge Beam
For optimum performance from SeaChanger and the Source Four when you need a soft edge, always
move the lens tube out (away from the lamp housing) from the focus point, not towards.
