Quad Scan LED
Trouble Shooting
Trouble Shooting: Listed below are a few common problems that
you may encounter, with solutions.
No light output from the unit;
1. Be sure the external fuse has not blown. The fuse is located on
the rear panel of the unit.
2. Be sure the fuse holder is completely and properly seated.
Unit does not respond to sound;
1. Low frequencies (bass) should cause the unit to react to sound.
Tapping on the microphone, quiet or high pitched sounds may
not activate the unit.
Fixture Cleaning:
Due to fog residue, smoke, and dust cleaning
the internal and external optical lenses and mirror should be carried
out periodically to optimize light output. Cleaning frequency depends
on the environment in which the fixture operates (I.e. smoke, fog
residue, dust, dew). In heavy club use we recommend cleaning on a
monthly basis. Periodic cleaning will ensure longevity, and crisp out-
put.
1. Use normal glass cleaner and a soft cloth to wipe down the out-
side casing.
2. Use a brush to wipe down the cooling vents and fan grill.
3. Clean the external optics and mirror with glass cleaner and a soft
cloth every 20 days.
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
back in.

Disconnect the unit from its power source. Remove the power cord
from the unit. Once the cord has been removed, you will find that
the fuse holder is 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 also
has a holder for a spare fuse.
