Caution: Do not force the rollers to turn when moving them by hand. If
they do not turn easily, you have not disconnected the color changer from
the power supply and should do so immediately
.
Remove the old gelstring
This procedure is performed with no power to the color changer.
1. Place the color changer on a flat surface with the Forerunner logo
facing up.
2. Remove the front panel by unscrewing the two thumb screws at the
top right and left corners of the front door as shown in the first picture
on the left.
3. Gently roll the gelstring onto the left roller, exposing the clear leader
taped on the right roller.
4. Untape the leader from the right roller. Remove the tape from the
leader.
5. Roll the gelstring into a tube, slowly rolling it off of the left roller.
6. When you reach the clear trailer, untape it from the roller.
Hint: To save time, move all gelstrings to frame one via the DMX source
before disconnecting power.
Install the new gelstring
Note: Use gaffer's tape to attach the gelstrings to the rollers. Do not use duct tape or
masking tape.
