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 screw on the rear of the unit that holds the
lamp socket assembly cover in place.
3. After removing the thumb screw, slide out the cover from the rear
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.

Special Note: Line Termination.
When longer runs of cable are
used, you may need to use a terminator on the last unit to avoid erratic
behavior. A terminator is a 90-120 ohm 1/4 watt resistor which is con-
nected between pins 2 and 3 of a male XlR connector (DATA + and
DATA -). This unit is inserted in the female XlR connector of the last
unit in your daisy chain to terminate the line. Using a cable terminator
(ADJ part number Z-DMX/T) will decrease the possibilities of erratic
behavior.

Termination reduces signal errors and
avoids signal transmission problems
and interference. It is always advisable
to connect a DMX terminal, (Resistance
120 Ohm 1/4 W) between PIN 2 (DMX-)
and PIN 3 (DMX +) of the last fixture.

5-Pin XLR DMX Connectors.
Some manufactures use 5-pin XlR
connectors for DATA transmission in place of 3-pin. 5-pin XlR fixtures
may be implemented in a 3-pin XlR DMX line. When inserting stan-
dard 5-pin XlR connectors in to a 3-pin line a cable adaptor must be
used, these adaptors are readily available at most electric stores. The
chart below details a proper cable conversion.
