Installing or removing beam containment devices and color frames:
Step 1: Push the latch on top of the scroller cartridge toward the back of the fixture head
to clear the accessory slot on the front of the cartridge.
Step 2: Insert or remove the beam containment device or color frame.
Step 3: Release the latch. It is spring-loaded and will slide back into the locked position
upon release. If the safety tether is present, attach it to the installed beam
containment device.
Gel Strings
You can change the gel string in your fixture. Replacement strings must have a minimum
of 2 frames or a maximum of 20 frames of gel media. If you are going to make or purchase
your own gel strings, follow the specifications below to ensure proper performance.
Replacing the gel string:
Step 1: Remove the scroller cartridge from the fixture by pulling the latch forward and
pulling the cartridge up out of the head. The gel string is held in tension and may
roll back after being released from the head.
Step 2: Place the cartridge on a flat surface and, if necessary, wind the gel string back
onto the right spool.
