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
z Make sure that the projector power supply is switched off before attaching or detaching the
projection lens.
z After removing the projection lens, store it safely away from vibration or impacts.
z Do not touch the electrical contacts of the projection lens with your fi ngers. Dust and dirt on
the contacts may cause contact malfunctions, while static electricity may damage the unit.
z Do not touch the surface of the lens with bare hands. Finger prints and dirt on the surface
of the lens will be magnifi 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.
z The lens is made of glass. The lens could be damaged if brought into contact with or
rubbed against hard objects. Handle the lens carefully.
z Use a clean, soft and dry cloth to wipe away dust and dirt from the projection lens.
Do not use fl uffy cloths containing oil, water or dust for cleaning. The lens is easily
damaged, so do not apply excessive pressure when wiping it.
