8. Using Optional Lenses
Five optional lenses are available for the NP2000/NP1000. See the information described on this page to buy the
appropriate lens for your screen size and throw distance. See page 11 5 for installing the lens.

 Table of Throw Distances and Screen Sizes for Optional Lenses
STANDARD (H X 1.5) - (H X 2.0)
NP01FL (H X 0.8)
NP03ZL (H X 1.9) - (H X 3.1)NP04ZL (H X 3.0) - (H X 4.8)
NP05ZL (H X 4.6) - (H X 7.0)
NP02ZL (H X 1.2) - (H X 1.5) 
Example: Distance from a 100 screen with the lens NP03ZL
Referring to the diagram on page 124, H is 2.0 m/78.7. Therefore, the projection distances of 100 inches are from
2.0 m/78.7 × 1.9 to 2.0 m/78.7 × 3.1 = from 3.8 m/150 to 6.2 m/244.
NOTE: Distances may vary +/-5%
For screen sizes between 30 and 500 not indicated on the above table, use formulas below.
Throw distance for Standard lens (m/inch)=H × 1.5 through H × 2.0 Distance from 0.89m to 20.83m/35.1 to 820.2
Throw distance for NP01FL(m/inch)=H × 0.8 Distance from 0.64m to 2.5m/25.3 to 98.6
Throw distance for NP02ZL(m/inch)=H × 1.2 through H × 1.5 Distance from 0.7m to 16.1m/27.5 to 634
Throw distance for NP03ZL(m/inch)=H × 1.9 through H × 3.1 Distance from 1.56m to 32.15m/61.4 to 1265.6
Throw distance for NP04ZL(m/inch)=H × 3.0 through H × 4.8 Distance from 3.6m to 49.52m/141.7 to 1949.5
Throw distance for NP05ZL(m/inch)=H × 4.6 through H × 7.0 Distance from 7.65m to 74.36m/301.3 to 2927.5

9. Appendix
If there is no picture, or the picture is not displayed correctly.
•Power on process for the projector and the PC.
Be sure to connect the projector and notebook PC while the projector is in standby mode and before turning on the
power to the notebook PC.
In most cases the output signal from the notebook PC is not turned on unless connected to the projector before
being powered up.
NOTE: You can check the horizontal frequency of the current signal in the projector’s menu under Information.  If it reads “0kHz”,
this means there is no signal being output from the computer. See page 104 or go to next step.
•Enabling the computer’s external display.
Displaying an image on the notebook PC’s screen does not necessarily mean it outputs a signal to the projector.
When using a PC compatible laptop, a combination of function keys will enable/disable the external display.  Usu-
ally, the combination of the ‘Fn” key along with one of the 12 function keys gets the external display to come on or
off.  For example, NEC laptops use Fn + F3, while Dell laptops use Fn + F8 key combinations to toggle through
external display selections.
•Non-standard signal output from the computer
If the output signal from a notebook PC is not an industry standard, the projected image may not be displayed
correctly. Should this happen, deactivate the notebook PC’s LCD screen when the projector display is in use. Each
notebook PC has a different way of deactivate/reactivate the local LCD screens as described in the previous step.
Refer to your computer’s documentation for detailed information.
•Image displayed is incorrect when using a Macintosh
When using a Macintosh with the projector, set the DIPswitch of the Mac adapter (not supplied with the projector)
according to your resolution. After setting, restart your Macintosh for the changes to take affect.
For setting display modes other than those supported by your Macintosh and the projector, changing the DIP
switch on a Mac adapter may bounce an image slightly or may display nothing. Should this happen, set the DIP
switch to the 13” fixed mode and then restart your Macintosh. After that, restore the DIP switches to a displayable
mode and then restart the Macintosh again.
NOTE: A Video Adapter cable manufactured by Apple Computer is needed for a PowerBook which does not have a mini D-Sub
15-pin connector.
•Mirroring on a PowerBook
*When using the projector with a Macintosh PowerBook, output may not be set to 1024 x 768 unless “mirroring”
is off on your PowerBook. Refer to owner’s manual supplied with your Macintosh computer for mirroring.
•Folders or icons are hidden on the Macintosh screen
Folders or icons may not be seen on the screen. Should this happen, select [View] → [Arrange] from the Apple
menu and arrange icons.
