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

The projector leaves the factory with no lens mounted. To protect the engine from e.g. dust, the lens gap is sealed with a foam
cover. Remove the foam cover before lens mounting.
How to remove the mounted lens
1. Support the lens with one hand. (image 1-1)
2. Move the lens lock (A) to the left to unlock the lens securing system.
3. Carefully pull the lens backwards to disconnect the lens zoom connector (B).
4. Take the lens out the lens block.

1.3 Lens installation
How to install a lens ?
1. Unlock the lens securing system by putting the lock handle to the left (A). (image 1-2)
2. Move the rear of the lens into the lens block, lining up the lens plug with the lens connector (B) (image 1-2).
3. Carefully push on the lens until the connector seats into the socket.
Note: On the lens block a reference pin (B) is provided to center the lens. For that reason the lens body is provided with a
notch (A) which has to match the reference pin after the lens plug connection into lens socket. (image 1-3)
4. Pull the handle (A) to the right to lock the lens securing system (image 1-2).

1.4 Cleaning the lens
To minimize the possibility of damaging the optical coating or scratching exposed lens surface, we have de-
veloped recommendations for cleaning the lens. FIRST, we recommend you try to remove any material from
the lens by blowing it off with clean, dry deionized air. DO NOT use any liquid to clean the lenses.

Necessary tools
TorayseeTM cloth (delivered together with the lens kit). Order number : R379058.
Howtocleanthelens?
Proceed as follow :
1. Always wipe lenses with a CLEAN TorayseeTM cloth.
2. Always wipe lenses in a single direction.
Warning: Do not wipe back and forwards across the lens surface as this tends to grind dirt into the coating.
3. Do not leave cleaning cloth in either an open room or lab coat pocket, as doing so can contaminate the cloth.
4. If smears occur when cleaning lenses, replace the cloth. Smears are the first indication of a dirty cloth.
Do not use fabric softener when washing the cleaning cloth or softener sheets when drying the cloth.
Do not use liquid cleaners on the cloth as doing so will contaminate the cloth.
Other lenses can also be cleaned safely with this TorayseeTM cloth.

2. LENS SPECIFICATIONS
2.1 Lens Formula
Calculation of the Projector distance (PD) as function of the Screen Width (SW)
Lens Formula
XLD(1.45 - 1.8:1) PDmin=1.45 x SW
PDmax=1.80 x SW
Due to production tolerances the real distances can differ by 2% from these calculated values.
For critical situations (fixed installs that use the lens at one of its extreme zoom positions) this should be
taken into account.
2.2 Projector Distance determination
Reference for measuring the PD
PD
