The period of guarantee begins on the date of transfer of risks, in the case of special systems and software on the date of commissioning,
at latest 30 days after the transfer of risks. In the event of justified notice of complaint, Barco can repair the fault or provide a replacement
at its own discretion within an appropriate period. If this measure proves to be impossible or unsuccessful, the purchaser can demand a
reduction in the purchase price or cancellation of the contract. All other claims, in particular those relating to compensation for direct or
indirect damage, and also damage attributed to the operation of software as well as to other services provided by Barco, being a component

2. Installing the lens
2. INSTALLING THE LENS
Overview
• Preparations
• Mounting the lens
• Connecting the lens
2.1 Preparations
How to prepare the projector lens holder ?
1. Turn in the 3 Allen screws M4.

Image 2-1
2. Turn a nut M4 on the Allen screws. Do not fasten yet.
How to prepare the projector ?
1. Ensure the lens shift mechanism on projector is not locked.
2.2 Mounting the lens
What has to be done ?
The lens has to be mounted on the projector’s lens holder. The lens holder has three mounting points i.e. 3 threaded screws
mounted with springs.

2. Installing the lens
2.3 Connecting the lens
What must be done ?
The lens must be connected to the projector to allow the control of the Zoom and Focus and to allow data communication for the
aperture control.
Insure that the lens is always connected to the projector. Not doing this will possibly damage the lens aperture
and will not allow optimal aperture control.
Never change the lens when the projector is ON. Always insure that the projector is in standby or OFF.
How to connect the lens ?
1. Connect the male connector attached to the lens to the female connector located on the front of the projector.
Tip: The side labeled TOP on the male connector must be orientated upwards.

What can be done ?
The position of the lens can be adjusted. The lens can be turned inside or outside the projector chassis . By doing that, the back
focal length is adjusted and the focus is set to an optimal value. This adjustment will allow to benefit from the largest adjustment
range for the lens focus (motorized lens focus).
