Optional Lens Installation
This section describes how to install the lens.
Before installation
* Determine the optional lens to be used to obtain a desired projection distance. There are six optional lenses available:
0.64 : 1 fixed part no. 102-373
0.96 : 1 fixed part no. 102-835
1.2 - 1.44 : 1 zoom part no. 102-374
1.44 - 1.8 : 1 zoom part no. 102-375
1.8 - 2.4 : 1 zoom part no. 102-376
2.4 - 3.6 : 1 zoom part no. 102-377
3.6 - 5.6 zoom part no. 102-378
* Press the power button (ON/STAND BY) on the projector or POWER OFF button on the remote control for a minimum of two seconds to turn
off the power, wait 90 seconds for the cooling fan to stop, then disconnect the power cable.
Check that the projector has cooled off sufficiently before proceeding.
CAUTION
* The projector and lens contain high-precision parts. Do not induce shock to the projector or the lens.
* Do not touch the lens surface. Doing so can degrade the optical performance.
Preparation: Tools needed for installation:
A cross head screwdriver.
NOTE: It is possble that the ‘Lens Shift’ feature (described on the previous page and in Section 3. Projecting an Image) may have used to move the
lens mount to the far right side, making installation difficult. If this is the case, then turn the projector back on again and use the Position buttons to
shift the lens back towards the mid-position. When this has been done, turn the projector off as decribed above, before continuing.
1. Remove the rear lens cover, but leave the front cover on to protect the lens surface during installation.
2. Insert the lens into the lens mount with the connector to the right, taking care to line up the locating pin on the lens with the locating hole above
the opening. Push the lens in firmly to engage the connector.
3. Secure the lens using the three cross-head screws.
NOTE. Remove the lens cover before use
