nal optical lenses must be carried out periodically to optimize light
output.

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.

unit in.

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.

onds of inactivity. This is a way of extending lamp life, be assured this
is not the problem with the fixture.
