3. To remove a rotating gobo, pull it gently
towards the lens until you can slide it up
and out of the two leaf springs that secure
it.
4. To install a gobo, slide the flange on the
edge of the gobo down between the
springs and the gobo wheel until the gobo
can be located in its aperture in the gobo
wheel. Check that it is held securely and
that the teeth around the edge of the gobo
are engaged in the cog in the center of
the gobo wheel.
5. To remove a color filter, turn the gobo
wheel so that the open position (arrowed
in Figure 10) is in front of the filter. Gently
press the filter towards the lens to release
it and then grasp it by the edges and
remove it. If your fingers are too large,
protect the glass with a piece of paper
that has been folded several times and
grasp the filter with needle nose pliers.
6. To install a color filter, slide it under the retention spring until it snaps into place.
7. Close the access hatch, pressing firmly until there is a definite click.
Replacing rotating gobos
Important! The gobo can fall out if the spring is inserted the wrong way round.
The gobos are held in goboholders by a retention spring (see Figure 11).
Note that the retention spring can only be used with gobos maximum 3
mm thick. Thicker gobos can be glued to the holder with a UV adhesive or
Loctite 330 Multibond with Activator.
To replace a rotating gobo
1. Put on clean, lint-free, heat-resistant gloves to protect your fingers and
avoid getting oil on optical components
2. Remove the gobo as described on page 27.
3. With a small screwdriver or similar, unhook the end of the gobo spring
furthest from the gobo and pull out the spring. Drop the gobo out of the
holder.
4. Insert the new gobo in the holder with the side that faces towards the
LEDs facing upwards, towards the spring (see Figure 8 and Figure 11).
5. Insert the spring with the narrow end against the gobo, as shown in
Figure 11. To identify the narrow end, press the spring flat: the narrow end is on the inside. Push the end
of the spring in under the lip of the holder.
6. Check that the gobo is seated flush against the holder. Press the spring as flat as possible against the
back of the gobo.
7. Work the rim of the goboholder under both clips on the gobo wheel until you can snap the goboholder
back into position. If necessary, lever the clips away from the wheel slightly with a small screwdriver or
similar tool.
8. Close the access hatch, pressing firmly until there is a definite click.

and press [Enter].
Run the focus car to the rearmost limit of its travel (i.e. furthest back towards the LEDs) where it is
pressing both end stop switches fully closed. Adjust the focus car forwards slightly until you hear an
audible click from the end stop switches as they open. Press [Enter] to save the setting. Replace the
bottom head cover.
3. Pan calibration is easiest when multiple fixtures are stacked vertically. To calibrate, set tilt positions for
easy one-over-the-other comparison and set each fixture to the same pan DMX value. Select one fixture
