E – 14 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 three minutes 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.

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 commercially available RGB signal cables 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.Slave projector Foot Depression for foot3-1-3. 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). 3-1-5. Store all the adjustments on a CompactFlash card from the master projector. 3-1-5-1. Insert a CompactFlash card into the PC Card slot. NOTE: Be sure to insert a CompactFlash card into the PC Card slot with itsfront side facing downward. 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 CompactFlash card, the POWER indicator will change to orange. 3-1-5-3. Remove the CompactFlash card from the slot of the master pro- jector. 3-1-6. Transfer the data to the other slave projector using the CompactFlash card so that all the projectors have the same data in memory. 3-1-6-1. Insert the CompactFlash card into the slot of the slave projector. NOTE: Since data in the slave projector 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 CompactFlash card to the slave projector. After copy- ing data to the slave projector, the POWER indicator will change to or- ange. 3-1-6-3. Remove the CompactFlash 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-41 for changing to RGB source. 3-1-6-4. 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-45 for Keystone correction. This completes set-up and adjustments. An image is projected from the master projector. See page E-50 for Link mode. NOTE: Up to two units can be gravity stacked without external support. In some cases, however, two images will not align on the screen correctly. This will become more apparent when displaying small text and detailed graphics. 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 – 17 6) Link Mode Setting 6-1 Assign a unique Projector ID for each projector. 6-1-1. Select [Projector Options] → [Setup] →[Page 5] → [Projector ID]. See page E-50 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 5] → [Communica- tion Speed]. See page E-50 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 projector. See page E-50 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 an unregistered signal, the master projector displays the image, but the slave projector doesnt. To view the information on the currently displayed signal, select [Help] → [Source In-formation] → [Page1]. 6-5 Make adjustments to the slave projector. NOTE: See “List of Menu Items Available on Link Mode” on page E-62 formore information. 6-5-1. Temporarily, change the master projector from Master to Standalone. Make sure that the slave projector is 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. NOTE: The optional lenses for GT2150 have different geometrical distortions in wide zoom and tele. Select the best zoom position for stacking where the geo- metrical distortion is as small as possible. See page E-63 for the recommended throw distances and other notes.

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 32˚F (0˚C) and 95˚F (35˚C). •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
