INTRODUCTION

®

The InFocus

LP™425z lightweight multimedia projector is spe­cifically designed for the mobile presenter. It generates crisp,
clear SVGA 800x600 images using Digital Light Processing™
(DLP) technology. The projector is easy to connect, easy to use,
and easy to maintain. The soft carry case makes it easy to trans­port the 7.4 pound projector.

Image Resolution

The SVGA resolution of the 425z’s projected image is 800x600.
Screen resolutions between 800x600 and 1024x768 are com­pressed to 800x600. The 425z cannot compress screen resolutions
above 1024x768. If your computer’s screen resolution is higher
than 1024x768, reset it to a lower resolution before you connect
the projector.

Compatibility

The projector is compatible with a wide variety of computers and
video devices, including:

•

IBM-compatible computers, including laptops, up to 1024x768
resolution at 75 Hz

NOTE: The 425z automatically

expands 640x480 images to

800x600. You can display these

images at 640x480 by turning off

the Auto Resize feature. See

“Resize” on page 21.

•

Apple Macintosh and PowerBook computers up to 1024x768
resolution at 75 Hz.

Introduction

Usage Guidelines

•

Do not look directly into the projection lens when the projector
is turned on. The bright light may harm your eyes.

•

Do not block the grills on the projector. Restricting the air flow
can cause it to overheat and turn off. If this happens, you must
wait a minute before attempting to turn it back on.

•

Handle the projector as you would any product with glass
components. Be especially careful not to drop it.

•

Avoid leaving the projector in direct sunlight or extreme cold
for extended periods of time. If this happens, allow it to reach
room temperature before use.

•

This projector is not intended for use in mainframe computer
rooms as defined in the Standard for the Protection of Elec­tronic Computer/Data Processing Equipment, ANSI/NFPA 75.

•

Transport the projector in a vendor-approved hard or soft case.
Part numbers for these cases are listed on page 37.

The projector is compatible with these major broadcast video
standards: NTSC, NTSC 4.43, PAL, PAL-M, PAL-N, and SECAM.
It automatically adjusts to optimize its performance for the
incoming video. The input signals for SECAM, PAL-M, and
PAL-N video are similar to other video signals and cannot be
automatically detected, therefore they must be chosen manually.
See “Video Standard” on page 23 for details.

may also have a “Video Out” port

for a coaxial cable connection.

DO NOT use this to connect to the

projector.

the keypad to move the cursor up and down to the item you want
to change (the selected item is highlighted red), then use the left
and right mouse buttons (not the left and right arrow buttons) to
adjust a setting. Some submenus, such as Brightness, consist of a
slider bar you use to increase or decrease a value; some sub­menus, such as Standby Time, consist of options you scroll
through to select the desired one. All changes are saved when
you close the menus.

NOTE: Some menu items may be

grayed out at certain times. This

indicates the item is not applicable

to your setup (for example, video

standards do not apply to com-

puter sources) or the item is not

enabled until another selection is

made (for example, Manual Track-

ing is not available until Auto

Image is turned off).

Video Standard

When Video standard is set to Auto, the projector attempts to
pick the video standard (NTSC, NTSC 4.43, PAL, PAL-M, PAL-N,
or SECAM) automatically based on the input signal it receives.
(The video standard options may vary depending on your region
of the world.) The input signals for SECAM, PAL-M, and PAL-N
video cannot be automatically detected, therefore they must be
chosen manually. If the projector is unable to detect the correct
standard, the colors might not look right or the image might
appear “torn.” If this happens, manually select a standard by
clicking either mouse button and cycling through the standards.

NOTE: If you already know the

video standard used in your geo-

graphical area, it’s often best to

manually select it.

Standby Time

This option lets you select how long the lamp stays on and the
blank screen is displayed when the projector enters standby
mode before the projector turns off. Select among 1, 5, 10, and 15
minutes and 1 and 2 hours by clicking either mouse button and
cycling through the options.

Ceiling Projection

When you turn

Ceiling Projection

on, the projector turns the
image upside down for ceiling-mounted projection. Highlight

MAINTENANCE & TROUBLESHOOTING

This section describes how to:

•

clean the lens

•

replace the projection lamp

•

use the security lock feature

•

troubleshoot the projector

Cleaning the Lens

Follow these steps to clean the projection lens:

Apply a non-abrasive camera lens cleaner to a soft, dry cloth.

•

Avoid using an excessive amount of cleaner.

•

Abrasive cleaners, solvents or other harsh chemicals might
scratch the lens.

Lightly wipe the cleaning cloth over the lens.

2

If you don’t intend to use the projector immediately, replace

3

the lens cap.

Replacing the Projection Lamp

The lamp hour counter in the Status menu counts the number of
hours the lamp has been in use. The projectors use a metal halide
bulb. These types of bulbs deteriorate over time. Replace the
lamp when the brightness is no longer acceptable. You can order
new lamp modules from your InFocus dealer. See “Accessories”
on page 37 for information.

Follow these steps to replace the projection lamp:

Turn off the projector and unplug the power cord.

1

Wait 30 minutes to allow it to cool thoroughly.

2

Place the projector on its side, then insert a small screwdriver

3

or other flat object into the tabs on the lamp module door (Fig­ure 19).

Pull the lamp door up and remove it.

Troubleshooting

Problem: Nothing on projection screen

•

Make sure that the power cord is properly connected to a fully

functional AC electrical outlet. Make sure that the power cord
is also properly connected to the projector.

•

If the projector is plugged into a power strip, make sure the

power strip is turned on.

•

Make sure you have removed the lens cap on the projection

lens at the front of the projector.

•

Make sure the projector is switched on.

•

Check the projector’s lamp to ensure that it is securely con-

nected in the lamp module. See “Replacing the Projection
Lamp” on page 27.

•

Make sure that the cables do not have any bent pins.

Problem: Color or text not being projected

•

You might need to adjust the brightness up or down until the

text is visible. Refer to “Brightness” on page 18 for more infor­mation.

Problem: The screen resolution is not right

•

Make sure the computer ’s video card is set for a resolution of

no greater than 1024x768.

Problem: Image isn’t centered on the screen

•

Reposition the image. Refer to “Horizontal position” on

page 22 and “Vertical position” on page 22.

•

Be sure the projector is at a 90 degree angle to the screen.

Problem: Only the start-up screen displays

•

Verify that the cables are connected correctly. See page 7

through page 8 for connection procedures.

•

Verify that the proper input source is connected. See “Source”

on page 15.

31

Maintenance & Troubleshooting

•

You might need to turn everything off and power up the

equipment again in the proper order. Refer to your com­puter’s documentation to determine the correct order.

•

Make sure your laptop’s external video port is turned on. See

the “Portable and Laptop Activation Chart” on page 39 or
your computer’s manual for details.

•

Make sure your computer’s video board is installed and con-

figured correctly.

If you’re using Windows 3.x:

In the Windows Program Manager, double-click the Win-

1

dows Setup icon in the Main program group.

Verify that the Display setting is 1024x768 or less.

2

If you’re using Windows 95:

Open “My Computer” icon, the Control Panel folder and

1

then the Display icon.

Click the Settings tab.

2

Verify that the Desktop area is set to 1024x768 or less.

3

Also check the following:

•

Does your computer have a compatible video board? The pro-

jector isn’t CGA or EGA compatible.

•

Is your computer’s video port activated? This is especially

true for laptop computers. See “Portable and Laptop Activa­tion Chart” on page 39.

Problem: Image is too wide or narrow for screen

•

You might need to manually adjust the tracking to reduce or

enlarge the projected image. Refer to “Manual Tracking” on
page 22.

•

The problem could be with your computer’s video card. If

possible, connect a different computer.

33

Maintenance & Troubleshooting

Problem: Projected colors don’t match the computer or video
player’s colors

•

Just as there are differences in the displays of different moni-

tors, there are often differences between the computer image
and the projected image. Adjust the brightness, tint and/or
contrast from the Display menu. See “Brightness” on page 18,
“Tint” on page 18 and “Contrast” on page 18.

Problem: Lamp seems to be getting dimmer

•

The lamp begins to lose brightness when it has been in use for

a long time. Replace the lamp as described in “Replacing the
Projection Lamp” on page 27.

Problem: Lamp shuts off

•

A minor power surge may cause the lamp to shut off. Turn the

projector off, wait at least a minute, then turn it back on.

Using Video Mirroring with a PowerBook Computer

When you turn video mirroring (called SimulScan in newer Pow­erBooks-see below) on, the projector displays the same informa­tion that appears on your PowerBook’s built-in screen. When
video mirroring is off, the projector acts like a separate display.

To turn on video mirroring for the first time:

Open the Monitors control panel; click on Monitor 2.

1

Set the number of colors you want.

2

Open the Control Strip; click on the monitor icon.

3

Select “Turn Video Mirroring On.”

4

Now you can turn video mirroring on and off from the Control
Strip without having to open the Monitors control panel again.

When using video mirroring and high color graphics such as
slide shows, the projected image occasionally might turn black
and white. If this happens, perform the following steps:

Turn off video mirroring.

1

Open the Monitors control panel.

2

Move the white menu bar to Monitor 2 to set the projector as

3

the primary monitor.

Restart the PowerBook.

4

Using SimulScan

Some newer PowerBooks display images on an external monitor
or projector differently than previous ones. When using
SimulScan, the projector displays the same information that
appears on your PowerBook

To select SimulScan:

Open the Control Panel, then double-click Monitors and

1

Sound.

In the Resolution list, choose the SimulScan mode, then click

2

OK.

If this changes your display settings, a dialog box appears.

3

Click OK to confirm the change.
