If you should have any more questions, or remarks, please do not hesitate to contact our
technical support team via the following web site www.Barco.com/esupport.
1.3 Validating the correct orientation of the magnet in the manual
XL Lamp House
Contact the Barco helpdesk to receive the caliber magnet.
Image 1-1
To validate the correct orientation of the magnet, the XL Lamp House
must be removed from the projector. This procedure assumes that the
Lamp House is already removed from the projector.
Necessary tools
• Caliber magnet (north side of the magnet is painted in red)
• 3 mm Allen wrench
How to validate a manual Lamp House?
1. Position the Lamp House on a flat and stable table, with the UV filter side resting on
the table.

The magnet is located (1) on the bottom side of the Lamp House near the handle, but is
not visible at this moment.
2. To validate the magnet orientation, approach the red side (2) of the caliber magnet to
the left side of the Lamp House magnet.
- If the caliber magnet attracts to the Lamp House, the magnet is oriented correctly.
Nothing needs to be done.
- If the caliber magnet repels from the Lamp House, the magnet is oriented incorrectly.
