Fuse & Lamp Replacement
Caution:
Always replace with the exact same type lamp and fuse,
unless otherwise 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 fuses, 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
a slide out lamp assembly that is retained by two phillips screws.
1. Be sure to follow the proper handling procedures that deal with
discharge lamps.
2. Remove the two small screws (A,B) on the rear of the unit
3. After removing the screws, gently slide out the socket assembly
from the rear of the unit to expose the lamp.
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.
6. After replacing the lamp follow the optimization procedures on the
next page to be sure the lamp is center in the reflector
A

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.
5. Center the hot-spot (the brightest part of the beam) using the 3
adjustment screws. 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.
6. 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.
7. 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.

Fuse Replacement:
Locate and remove the unit’s power cord. Once
the cord has been removed located the fuse holder 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 has a built-in socket for a spare fuse
be sure not to confuse the spare fuse with active fuse.
