Read this rst! Always follow these precautions
WARNING:
Do not look at or place your skin into the light emitted from the lens while the
projector is being used.
Doing so can cause burns or loss of sight.

Note
zThis manual omits the alphabets at the end of projector model numbers.
zModels other than the above may also be supported. Refer to the operating instructions of
the projector you are using.
■Supplied Accessories
Make sure that the following has been provided.
Part name Appearance (quantity)
Lens cover
1 each
(The product is
delivered with a lens
cap attached.)
Before replacing the projection lens
Return the projection lens to the home position before replacing or removing it.
For details on how to return the lens to the home position, refer to the operating
instructions of the projector.
Attention
zMake sure that the projector power supply is switched off before attaching or detaching the
projection lens.
zAfter removing the projection lens, store it safely away from vibration or impacts.
zDo not touch the electric contact points of the projection lens with your ngers. Dust and
dirt on the contacts may cause contact malfunctions.
zDo not touch the surface of the lens with bare hands. Finger prints and dirt on the surface
of the lens will be magnied by the lens and lower the quality of the projected image. Place
the supplied lens cover on the zoom lens when the projector is not in use.
zThe lens is made of glass. The lens could be damaged if brought into contact with or
rubbed against hard objects. Handle the lens carefully.
zUse a clean, soft and dry cloth to wipe away dust and dirt from the lens.
Do not use uffy cloths containing oil, water or dust for cleaning. The material in the lens is
easily damaged, so do not apply excessive pressure when wiping it.

Perform the lens position shift within the adjustment range.
The focus may change when the lens position is shifted out of the adjustment range.
This is because the movement of the lens is restricted to protect the optical parts.
Projection position can be adjusted with the optical axis shift based on the home position
in the respective range.

Note
zA ±5 % error in listed projection distances may occur.
In addition, when [KEYSTONE] is used, distance is corrected to become smaller than the specied screen size.
zThe throw ratio is based on the value during projection with the projected image size of 2.03 m (80").
Remarque
zUne erreur de ±5 % dans des distances de projection énumérées peut se produire.
En outre, lorsque [CORRECTION DE TRAPÈZE] est utilisé, la distance est corrigée pour devenir inférieure à
la taille d’écran spéciée.
zLe rapport de projection est basé sur la valeur en cours de projection avec une taille de l’image projetée de
2,03 m (80").

6Appendix / Annexe
Setting-up dimensions which are not given in the above table can be calculated using the formulas below.
Check the projected image size SD (m) and use the following formula to determine projection distance (L).
La configuration des dimensions qui ne sont pas données dans le tableau ci-dessus peut être calculée à
l’aide des formules suivantes. Vérifiez la taille de l’image projetée SD (m) et utilisez la formule suivante
pour déterminer la distance de projection (L).
