6.7 Realignment of the lamp in its reflector
Each xenon bulb lamp installation requires a realignment of the lamp in its reflector for optimal performance
of the xenon bulb lamp in the DP-1500 projector. Furthermore, it is recommended to realign the lamp after the
first run time of 100 and 200 hours. Especially the Z-axis of the lamp.
WARNING: This procedure may only be performed by qualified technical service personnel.
How to realign the lamp in its reflector?
1. Remove the cover of the lamp compartment to gain ac cess to the X -, Y -, and Z-axis adjus tment thumbs crews of the lam p.
2. Switch on the projector and start up the lamp.
3. Go via the Communicator touch panel to the menu “Installation” > “Lamp” > “Light output”.
4. Set the “Light output mode”innormal mode and the “Lamp Dimming” on maximum (255).
Note: This window on the Communicator touch panel shows in the upper left corner the measured value of the built-in light
sensor of the projector.
