Performance Scan 250™ Breaker Reset
Optimizing Lamp Alignment: This procedure centers the lamp in the
reflector. Proper optimization will increase lamp life and ensure a bright
crisp output. Improper optimization may add a yellow tint to the lamp
output and reduce intensity.
1. Be sure main power is disconnected and allow the unit to cool. If
the you have just installed a new unit you can obviously skip this
step.
2. Make a preliminary adjustment: Turn the three lamp adjustment
thumb screws completely in (clockwise). Then back them each
out (counter-clockwise) about three complete turns.
3. Turn the unit on and allow it to reset.
4. Using either a DMX controller or the control panel on the unit,
strike the lamp and focus the light on a flat surface.
6. Center the hot-spot (the brightest part of the beam) using the 3
adjustment screws (A,B,and C). Turn one screw at a time to drag
the hot-spot diagonally across the projected image. If you
cannot detect a hot-spot, adjust the lamp until the light is even.
7. To reduce a hot-spot, pull the lamp in by turning all three screws
clockwise 1/4-turn at a time until the light is evenly distributed.
8. If the light is brighter around the edge than it is in the center, or if
light output is low, the lamp is too far back in the reflector. “Push”
the lamp out by turning the screws.

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.
Performance Scan 250™ Lamp Replacement
Caution: Always replace with the exact same type lamp, unless oth-
erwise specified by an authorized American DJ

your unit and will void your manufactures warranty.

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 slide out lamp socket assembly that is retained by thumb
screws.
1. Be sure to follow the proper handling procedures that deal with
discharge lamps.
2. Unscrew and remove the two thumb screws at the rear of the
unit.
3. After removing the thumb screws, slide the lamp socket assembly
out.
4. Carefully remove the old lamp.
5. Replace the lamp with an exact match and reassemble in reverse
order.
This fixture is fitted with halogen lamps which are
highly susceptible to damage if improperly han
-
dled. Never touch the lamps with your bare fingers
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.
