Before Use
Detaching the lens / Attaching the lens
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 instruc-
tions 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.
zBefore attaching the lens, be sure to remove the two lens caps (1 each for front and rear)
attached to the lens.
zDo not touch the electric contact points of the projection lens with your fingers. 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 magnified by the lens and lower the quality of the projected image. Place the
supplied lens cap 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 fluffy 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.
