Installing the Projection Lens
The projector is supplied without any lens.
Remark :
To install a projection lens, the projector must be switched ON as the lens bridge must be shifted upwards.
Installation of QLD lenses :
Remove the foam rubber in the opening of the lens holder.
1 Switch on the projector.
2 Push 3x on the HELP key.
3 Push the é key to pull up the lens bridge (zoom & focus part of the lens housing)
4 Take the new lens out of its shipping carton and remove the lens covers.
5 Turn the lens into the lens holder by turning clockwise.
6 Push the ê key to bring the lens bridge back on its position.
7 Press EXIT to return to operational mode.
Installation of LD lenses :
LD lens will be delivered with an adapter ring.
They can be mounted in the same manner as QLD lenses.
No motorized zoom function is standard available. To add this motorized zoom function to the lens, a zoom ring kit has to be ordered
separately.
Zoom ring kits :
For LD(2.5-4:1) and LD(4-7:1) lens : R9840310
For LD(1.5-2.5:1) lens : R9840320
Use of lenses of competitors.
The lenses of competitors can be used in this ELM projector in combination with a lens mount adapter ring kit. This kit can be ordered
separately, order number : R9840370.
Why using an adapter ring? The ELM lens holder has been designed for QLD type lenses. These lenses in turn have been designed
for the SXGA DLP chip. This chip is bigger than the XGA chip. In order to offer sufficient lens shift capabilities and corner focus
performance, the diameter of the QLD lenses is larger than the LD type.
Cleaning the lens
To minimize the possibility of damaging the optical coating or scratching exposed lens surface, we have developed 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.
A Toraysee TM cloth is included with the lens kit.
Proceed as follows :
1. Always wipe lenses with a CLEAN Toraysee
TM
cloth.
2. Always wipe lenses in a single direction. 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.
5. Do not use fabric softener when washing the cleaning cloth or softener sheets when drying the cloth.
6. Do not use liquid cleaners on the cloth as doing so will contaminate the cloth.
Order number for a new Toraysee TM cloth : R379058.
