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 you have connected your unit into a standard 120v
wall outlet.
2. Be sure the external fuse has not blown. The fuse is located
on the back panel of the unit inside the power socket.
3. Remove the lamp holder and be sure the lamp is seated in
its socket properly. Occasionally lamps become loose dur-
ing shipping be sure the lamp is push in to its socket all the
way.
4. 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 clean-
ing the internal and external optical lenses and mirror should be
carried out periodically to optimize light output. Cleaning fre-
quency depends on the environment in which the fixture oper-
ates (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 output.
1. Use normal glass cleaner and a soft cloth to wipe down the
outside 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.
