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 four optional lenses available:
GT10RL (Fixed short throw lens)
GT19ZL, GT13ZL and GT34ZL (Zoom lens)
* Press the power button (ON/STAND BY) on the projector or POWER OFF button on the remote control, wait ONE minute 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 hexagonal driver and dust-protective sheets are supplied with the optional lens.
1. Remove the lens hood cap and lens hood.1 Press and hold the catches on both ends of the lens hood cap, and 2 then remove it.
3  Loosen the 4 screws on the lens hood using the hexagonal driver until the hexagonal driver goes into a freewheeling condition and 4 remove
the lens hood. The 4 screws are not removable.

Setting up for Double Stacking in Link Mode
Master projector
NOTE: SW 1 Level and SW 2 Level of Switcher Control are not available on LinkMode.
For double stacking, follow the instructions described below.
1) Stacking the Projectors
1-1. Place the projectors at the proper height for best screen to projec-
tor relationship. Make sure that all projectors have the same display
orientation.
2) Hookup
2-1. Use the supplied RGB signal cable to connect the RGB output of
the master projector to the RGB input of the slave projector until all
the projectors are connected.
2-2. Next, using a commercially available, bi-directional RS-232C cable
connect the PC CONTROL OUT terminal of the master projector to
the PC CONTROL IN terminal of the slave projector until all the
projectors are connected.
2-3. Turn all the projectors on and roughly make some optical adjust-
ments to each projector.
3) Adjusting and registering signals to be projected in Link
mode and stack application.
Signal Data Preparation
3-1. Create data for the master projector and copy data to the slave
projector.
3-1-1. Choose one projector as the master.
3-1-2. Turn the master projector on.
3-1-3. Display all desired input signals, make adjustment to each signal,
then save all adjustments on the master   projector. (Adjustments will be
saved automatically.)
3-1-4. Turn the master projector off (standby mode).Slave projector
Foot
Depression
for foot3-1-5. Store all the adjustments on a PC card from the master projector.
3-1-5-1. Open the PC Card slot cover to access the PC card slot. Insert
a PC card into this slot.
3-1-5-2. Press and hold CANCEL, then press POWER on the top panel
of the master projector. The POWER indicator will change to steady
green and the PC Card Access indicator will start flashing. After stor-
ing data on the PC card, the POWER indicator will change to orange.
3-1-5-3. Remove the PC card from the slot of the master projector.
3-1-6. Transfer the data to the other slave projectors using the PC card so
that all the projectors have the same data in memory.
3-1-6-1. Insert the PC card into the slot of a slave projector.
NOTE: Since data in the slave projectors will be lost at this time, makebackup copies of them before proceeding.
3-1-6-2. Press and hold ENTER, then press MENU on the top panel of
the slave projector. The POWER indicator will change to steady green
and the PC Card Access indicator will start flashing to indicate that
the data is being copied from the PC card to the slave projector. After
copying data to the slave projector, the POWER indicator will change
to orange.
3-1-6-3. Remove the PC card from the slave projector.
NOTE: If you select the RGB1 input on the master projector, you must
select the same input on the slave projector and the RGB2 on the master
projector and the slave projector.
NOTE: After adjusting and registering signals as mentioned above, you
must change the input to RGB on the Entry Edit Command window for
Link Mode. See Entry List Edit on page E-40 for changing to RGB source.
3-1-6-3. Display the desired source.
4) Display the internal crosshatch test pattern.
NOTE: Use a different single color for each projector. Example:Turn on Green of one projector (master), then Red of the other (slave).
5) Adjusting the lens shift, zoom and focus to clearly display
all projected patterns.
5-1. Adjust the Lens Shift using the LENS SHIFT button on the projec-
tor cabinet. You can also adjust the Lens Shift by pressing and hold-
ing CTL and pressing the POSITION button on the remote control.
For Lens Shift Adjustable Range, see page E-13.
5-2. Zoom the lens in and out by using the ZOOM button on the projec-
tor cabinet or the remote control.
5-3. Adjust the lens focus by using the FOCUS button on the projector
cabinet or the remote control.
NOTE: If the physical (vertical) alignment of the projector is not correct, adjust
the height of the feet. If there is any keystone distortion, use Keystone adjust-
ment to correct and save the settings on each projector. See page E-22 and E-
42 for Keystone correction.
This completes set-up and adjustments. An image is projected from the master
projector. See page E-49 for Link mode.
CAUTION: To prevent the projectors from falling, install them in a place andfasten them in a way with sufficient strength to support the two projectors. 
						

							E Ð 17
6) Link Mode Setting
6-1 Assign a unique Projector ID for each projector.
6-1-1. Select [Projector Options] ® [Setup] ®[Page 6] ® [Projector ID].
See page E-49 for specifying ID.
6-1-2. Specify a unique projector ID for each projector.
6-2 Select the same communication speed for all the projectors.
6-2-1. Select [Projector Options] ® [Setup] ®[Page 6] ® [Communica-
tion Speed]. See page E-49 for setting the communication speed.
6-2-2. Select the appropriate speed between 4800 and 38400.
6-3 Set the Link Mode on each projector.
6-3-1. Select [Projector Options] ® [Link Mode].
6-3-2. First select [Slave] on the slave projector.
6-3-3. Select [Master] on the master projectors. See page E-49 for setting
Link Mode.
6-4 Project a source image from all projectors
6-4-1. Display any signal onto the screen.
6-4-2. Check to see if the imags on the master projector are displayed in
syncronization with the ones on the other slave projector while the pro-
jectors are in link mode.
NOTE: Registering signals is not possible in the Link mode. To register a
signal, first set Link Mode to Standalone on the menu and then repeat
the above steps from 3. If you select a unregistered signal, the projector
will display a background image. To view the information on the currently
displayed signal, select [Help] ® [Information] ® [Page1].
6-5 Make adjustments to the slave projector.
NOTE: See ÒList of Menu Items Available on Link ModeÓ on page E-68 formore information.
6-5-1. Temporarily, change the master projector from Master to Standalone.
Make sure that the slave projectors are still in Slave mode.
6-5-2. Display a source you want to adjust from the master projector.
6-5-3. On the Slave Projector select the same signal From the Entry List
(same No.) as that of the master projector. Display it from the slave
projector.
6-5-4. Make Picture adjustment such as brightness, contrast, or color tem-
perature.
6-5-5. Change the master projector from Standalone to Master to activate
the Link Mode
6-6 This completes the Link Mode adjustment procedure.

WARNING
¥ Installing your projector on the ceiling must be done by a qualified
technician. Contact your NEC dealer for more information.
* Do not attempt to install the projector yourself.
¥ Only use your projector on a solid, level surface. If the projector falls
to the ground, you can be injured and the projector severely dam-
aged.
¥ Do not use the projector where temperatures vary greatly. The pro-
jector must be used at temperatures between 32ûF (0ûC) and 104ûF
(40ûC).
¥ Do not expose the projector to moisture, dust, or smoke. This will
harm the screen image.
¥ Ensure that you have adequate ventilation around your projector so
heat can dissipate. Do not cover the vents on the projector. Transparent screen
