Replacing the Projection Lamps

When a lamp fails, be sure to replace it with another EVD bulb (36 volt, 400 watt) from General Electric or OSRAM. These bulbs provide the best performance and longest bulb life.

You can order replacement lamps from In Focus. Refer to “Accessories” on page 43 for information.

Follow these steps to replace the lamps.

1.Press the “0” side of the LitePro’s power switch. Then, allow the LitePro to cool thoroughly (at least 20 minutes).

Allow the LitePro to cool for at least 20 minutes before you attempt to open the lamp door! The inside of the LitePro lamp housing can become very hot. Use extreme care.

2.While you’re waiting for the LitePro to cool, find a clean soft cloth that you can use to hold the bulbs. You can also use the plas- tic bag that came with the lamp. Holding a bulb with your bare fingers can damage the bulb and shorten its life.

3.Disconnect the power cord from the LitePro.

4.Open the lamp door. To do this, push in on the two buttons as shown below, then lift the door up.

5.Hold the lamp door open with one hand.
