Inserting/Exchanging Rotating Gobos - American DJ ULTRA SCAN 250 User Manual

Lamp adjustment
The lampholder is aligned at the factory. Due to differences between lamps, fine adjustment may improve light
performance.
Strike the lamp and focus the light on a flat surface (wall). Center the hot-spot (the brightest part of the beam)
using the 3 adjustment screws „X, Y, Z". Turn one screw at a time to drag the hot-spot diagonally across the
projected image. If you cannot detect a hot-spot, adjust the lamp until the light is even.
To reduce a hot-spot, pull the lamp in by turning all three screws „X,Y, Z" clockwise ¼-turn at a time until the light
is evenly distributed.
If the light is brighter around the edge than it is in the center, or if light output is low, the lamp is too far back in the
reflector. „Push" the lamp out by turning the screws „X,Y,Z" counterclockwise ¼-turn at a time the light is bright
and evenly distributed.

DANGER!
Instal the gobos with the device switched off only.
Unplug from mains before!
If you wish to use other forms and patterns as the standard-gobos, or if gobos are to be exchanged, please
follow the instructions below:
Remove the fixation-ring with an appropriate tool. Remove the gobo and insert the new gobo. Press the fixation-
ring together and insert it in front of the gobo.
CAUTION!
Never unscrew the screws of the rotating gobo
as the ball bearing will otherwise be opened!
