Listed below are a few common problems the user may encounter,
with solutions.
No light from the unit;
1. Check if the fan is running. If not, there is no main power supply.
2. Check the breaker 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. Check the dipswitch settings.
2. Check that the DMX cables are connected 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.
3. If DMX connectors are fairly short, ordinary microphone cables

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).
