7. Replacing fuse :
Disconnect from the main power supply first, then remove the fuse from the
IEC Socket or fuse holder . Replace with a fuse of the correct rating as stated
on product label or user guide.
8. General maintenance :
To maintain optimum performance and minimize wear, fixtures should be
cleaned frequently. Usage and environment are contributing factors in
determining frequency. As a general rule, fixtures should be cleaned at least
twice a month. Dust build-up reduces light output performance and can cause
overheating. This can lead to reduced lamp life and increased mechanical
wear. Be sure to power off fixture before conducting maintenance.
Unplug fixture from power. Use a vacuum or air compressor and a soft brush
to remove dust collected on external vents and internal components. Clean all
glass when fixture is cold with a mild solution to the cloth or tissue, and drag
dirt and grime to the outside of the lens. Gently polish optical surface until
they free of haze and lint.
The cleaning of internal and external optical lenses and/or mirrors must be
carried out periodically to optimize light output. Cleaning frequently depends

on the environment in which the fixture operates: damp, smoky or
particularly dirty surroundings can require cleaning fluid. Always dry the parts
carefully. Clean the external optics at least every 20 days.
9. Quick trouble shooting :
7.1 If the unit does not function – Check that the main power is on and the
fuse is intact.
7.2 If the unit is not reacting to music – check the unit is in “sound to light”
mode and that the sensitivity control is fully clockwise.
7.3 If the product is not reacting to DMX signals, check the cables and
connections
