FUSE REPLACEMENT
Locate and remove the unit’s power cord. Once the cord has been removed, locate the fuse holder
located inside the power socket. Insert a flat-head screw driver into the power socket and gently pry
out the fuse holder. Remove the bad fuse and replace with a new one. The fuse holder has a built-in
socket for a spare fuse, so be careful not to confuse the spare fuse with active fuse.
CLEANING
Due to fog residue, smoke, and dust, cleaning of the internal and external optical lenses must be
carried out periodically to optimize light output.
Use a soft cloth to wipe down the outside casing. Cleaning frequency depends on the environment
in which the fixture operates (i.e. smoke, fog residue, dust, dew).
TROUBLESHOOTING
Listed below are a few common problems the user may encounter, with solutions.
Unit not responding to DMX:
Check that the DMX cables are connected and wirely correctly (pin 3 is “hot”; on some other DMX
devices, pin 2 may be “hot”). Check that all cables are connected to the correct connectors in the
correct order. The way in which the input and output are connected can affect the operation of the
device.
Unit does not respond to sound:
Quiet or high pitched sounds will not activate the unit.
