Trouble Shooting
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 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 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.
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 breaker has not blown. The breaker is locat
ed on the bottom panel of the unit.
3. Remove the lamp cover and be sure the lamp is seated in its
socket properly. Occasionally lamps become loose during ship-
ping be sure the lamp is push in to its socket all the way.
Unit does not respond to sound;

not activate the unit.

ScanTron 250™ Lamp Replacement
Caution:
Always replace with the exact same type lamp, unless oth-
erwise specified by an authorized American DJ
®
service technician.
Replacing with anything other than the specified part can damage
your unit and will void your manufactures warranty.
Warning:
If you continue to blow lamps or the breaker, SToP using
the unit. Contact customer support for further instructions, you may
have to return the unit for servicing. Continuing to use the unit may
cause serious damage.
Lamp Replacement:
Caution! Never attempt to change the lamp
while the fixture is plugged in. Always disconnect the main power
and allow the unit ample time to cool before attempting to replace the
lamp. Lamp replacement has been made simple by incorporating the
use of a flip-up front cover that is retained by thumb screws.
1. Be sure to follow the proper handling procedures that deal with
halogen lamps.
2. Remove the thumb screws on the front of the unit that holds the
lamp socket assembly cover in place.
3. After removing the thumb screw, remove cover from the front
of the unit to expose the lamp socket assembly.
4. Carefully remove the old lamp and discard it in the trash.
5. Replace the lamp with an exact match and reassemble in reverse
order.
This unit is equipped with a built-in safety breaker. This breaker is
designed to close the power circuit in the event of an internal short
or power surge. This will reduce the risk of electrical shock or fire and
protect the circuitry. To reset the breaker, push the breaker button in
until you hear it “pop” back in to place. If the breaker continues to
pop, stop using the unit and contact our customer support team, the
unit may need to be returned for service.

Breaker Reset
This fixture is fitted with halogen lamps which are
highly susceptible to damage if improperly han-
dled. Never touch the lamps with your bare fin-
gers as the oil from your hands will shorten lamp
life. Also, never move the fixture until the lamps
have had ample time to cool. Remember, lamps
are not covered under warranty conditions.
