4. Installation
4.1 Fitting/Exchanging the lamp
DANGER !
Install the lamp with the device switched off only.
Unplug from mains before !
To insert the lamp MSD 250W/2 open the small cover at the rear of the projector by loosening the 3 screws „X, Y, Z" on
the lamp cover.
Gently pull out the lamp socket assembly.
If changing the lamp, remove the old lamp from the socket. Insert the lamp to the socket.
Do not install a lamp with a higher wattage! A lamp like this generates temperatures the device is not designed for.
Damages caused by non-observance are not subject to warranty. Please follow the lamp manufacturer's notes!
Do not touch the glass-bulb bare hand during the installation! Make sure that the lamp is installed tightly into the lamp
holder system.
Reinsert the lamp assembly and tighten the 3 screws again.
Before striking the lamp, reset the „LAti/rSEt" and „LASt/rSEt" counters in the „InFO" menu on the control panel, by
pressing the [Up] and [Down] buttons in one time and then confirming with the [Enter] button.
Do not operate this fixture with opened housing-cover!
4.2 Lamp adjustment
The lamp holder is aligned at the factory. Due to differences between lamps, fine adjustment may improve light performance.
Strike the lamp, cancel all effects, open the shutter and set the dimmer intensity to maximum and focus the light on a flat
surface (wall) or use function „LAAd" in the Special functions of the control board.
Center the hot-spot (the brightest part of the beam) using the 3 adjustment screws „A, B, 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.
To reduce a hot-spot, pull the lamp in by turning all three screws „A, B, C" clockwise 1/4-turn at a time until the light is
evenly distributed.
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 „A, B, C" counterclockwise 1/4-turn at a time the light is bright and evenly
distributed.
4.3 Installation of the barn-doors
You can install the barn-doors to better define the
