equivalent). Please remember there is only one way to insert the lamp and the lamp should fit completely in the lamp socket.

5.Once the lamp has been inserted into the socket, gently slide the socket assembly back into place and secure with the two Phillips screws.

6.Always be sure to optimize the lamp after lamp replacement.

The lamp orientation and optimization must be adjusted after every lamp change. 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. The minimum deviation amount is 1.0mm. Running the fixture within a lower deviation can cause damage to the lamp and/or lens.

The CMY Zoom 575™ lamp holder is aligned at the factory. However, due to slight imperfections in all lamps, fine adjustments will improve light performance. Please follow the procedure below for proper lamp optimization:

1.Using either a DMX controller or the control panel on the unit (see “SPOT” in the fixture menu on page 33), strike the lamp and focus the light on a flat surface (beam open, white, no gobo, no effect).

2.Center the hot-spot (the brightest part of the beam) using the 3 adjustment screws labeled 1, 2, and 3 as illustrated on the next page. 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.

3.To reduce a hot-spot, pull the lamp in by turning all three screws clockwise a 1/4-turn at a time until the light is evenly distributed.

4.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 each of the
