Listed below are a few common problems the user may encounter,
with solutions.
No light from the unit;
1. Check if the ‘Power On’ (red) LED is lit and the fan is running. If
not, there is no main power supply.
2. Check the fuse in the back panel.
3. Check if lamp is lit. The user should be able to see some light
escape through the fan. If power is present but the lamp is not lit,
lamp may need to be replaced.
Note: The unit has been designed to shut the lamp down after 60 sec-
onds of inactivity. This is a way of extending lamp life, be assured this
is not the problem with the fixture.
Unit not responding to DMX;
1. If the Green LED on the top of the unit is flashing, the unit is
definitely receiving DMX
2. Check the dipswitch settings.
3. If the DMX LED is not lit, check that the DMX cables are con-
nected properly and are wired correctly (pin 3 is ‘hot’; on some
other DMX devices pin 2 may be ‘hot’). Also, check that all cables

are connected to the right connectors; it does matter which way
the inputs and outputs are connected.
4. If it is a bad connection, the Green LED may flash when cables are
wiggled (but remember it may also be the unit sensing audio!)
5. If DMX connectors are fairly short, ordinary microphone cables
may be used. For longer runs, this may cause data transmission
problems (which will show up as random or incorrect movements)
for best result, use proper balanced data transmission cable.
Unit does not respond to sound;
1. Check to see if the unit is receiving DMX (the green LED should
be off).
2. Tapping the microphone should cause the LED to flash (quiet
or high pitched sounds will not activate the unit). If the red LED
does not flash to sound there may be an internal problem.
3. Be sure the audio sensitivity knob is turn in the full clockwise
position (maximum sensitivity).
Unit blacks out in stand alone mode;
1. Some of the units’ built-in patterns include special effects such
as blackout sweeps.
2. Be sure the audio sensitivity knob is turn in the full clockwise
position (maximum sensitivity).

Due to fog residue, smoke, and dust, cleaning the internal and exter-
nal optical lenses must be carried out periodically to optimize light
output.
1. Use normal glass cleaner and a soft cloth to wipe down the out-
side casing.
2. Use a brush to wipe down the fan grill.
3. Clean the external optics with glass cleaner and a soft cloth every
20 days. Situation may very. If used heavily in clubs with lots of
fog, cleaning may be required more often.
4. Clean the internal optics with glass cleaner and a soft cloth every
30-60 days.
5. Always be sure to dry all parts completely before plugging the
unit in.
Cleaning frequency depends on the environment in which the fixture
operates (i.e. smoke, fog residue, dust, dew).
