USING THE PROJECTOR
This section describes how to use and make adjustments to the
projector. It also provides a reference to the keypad and remote
buttons and the options available from the on-screen menus.
Basic Image Adjustment
Make sure you have powered up your equipment in the right
1
order (page 15).
If the image doesn’t display completely, adjust the height and
2
tilt of the projector (page 19), zoom the image (page 19), or
center the image by adjusting its horizontal or vertical position (page 30).
If the image is out of focus, rotate the lens to focus it (page 19).
3
If the image appears to shimmer or if it has blurry vertical
4
bars after you have adjusted the focus, turn Auto Image
(page 29) off and then back on to reset the automatic sync and
tracking. If that doesn’t clear up the image, adjust the sync
(page 29) and/or the tracking (page 30) manually.
If the colors don’t look right, adjust the brightness (page 22)
5
and tint (page 25).
NOTE: In Focus has created a
software program called In Focus
Presents that automatically optimizes your computer’s display
when used with any In Focus projector. This free program is
included with every projector and
available for download from our
web site at www.infocus.com.
Using the Remote Control
Point the remote control at the projection screen or at the top of
the projector. The range for optimum operation is about 25 feet. If
you point the remote at the projection screen, the distance to the
screen and back to the projector must be less than or equal to 25
feet. For best results, point the remote directly at the front or the
rear of the projector.
The projector ships with a full-feature remote (see page 21 for a
description of the buttons) which includes a laser pointer. The
remote has a disk mouse and two mouse buttons, one on the top
of the remote and one on the bottom (Figure 14).
NO TE: If you can’t aim the
remote control at the projector so
that its signal is received — for
example, when using rear projec-
—
tion
use the remote control

Using Video Mirroring with a PowerBook Computer
When you turn video mirroring on (called SimulScan in newer
PowerBooks-see below), 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 Sim ulScan:
Open the Control Panel, then double-click Monitors and
1
Sound.
In the Resolution list, choose the SimulScan mode, then click

OK.
If this changes your display settings, a dialog bo x appear s.

Cleaning the Lens
Follow these steps to clean the projection lens:
Apply a non-abrasive camera lens cleaner to a soft, dry cloth.
1
•
Avoid using an excessive amount of cleaner and applying
the cleaner directly to the lens.
•
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.
Cleaning the Fan Intake Filter
The fan intake filter on the bottom of the projector catches dust
and particles in the air. If the filter becomes clogged, the projector
does not cool properly and may malfunction. To prevent this,
clean the filter after every 100 hours of use.
Turn off the projector and unplug the power cord.
1
Remove the lamp door.

•
Remove the screw on the outside of the lamp door
(Figure 27).

Replacing the Projection Lamp
The lamp hour counter in the Status menu counts the number of
hours the lamp has been in use. After 3000 hours of use, the lamp
monitor LED, marked on the top of the projector near the
keypad, lights yellow. For optimum results, the lamp should be
replaced at this time. You can order new lamp modules from your
In Focus dealer. See “Accessories” on page 49 for information.
Follow these steps to replace the projection lamp:
Turn off the projector and unplug the power cord.
1
Wai t 30 minutes to allow it to cool thoroughly.
2
Using a small, flat-blade screwdriver, loosen the screw on the
3
outside of the lamp door (Figure 29).
Pull the lamp door up and remove it.
4
WARNING: To avoid burns,
allow the projector to cool for at
least 30 minutes before you open
the lamp module door. Never
extract the lamp module while the
lamp is operating.

Replacing the Batteries in the Remote Control
The life of the batteries depends on how often and how long you
use the remote. Symptoms of low battery charge include erratic
responses when using the remote and a reduced range of operation.
Follow these steps to replace the batteries:
Turn the remote face down in your hand.
1
Slide the battery cover off the end of the remote by pressing
2
on it with the heel of your hand.
Remove the old batteries.
3
Install two new AA alkaline batteries. Make sure you install
4
each in the correct direction.
Slide the battery cover back on the remote.
5
Using the Kensington Lock
The projector has a Kensington Security Standard connector for
use with a Kensington MicroSaver Security System (Figure 31).
Refer to the information that came with the Kensington System
for instructions on how to use it to secure the projector.

Maintenance & Troubleshooting
Troubleshooting
If you’re experiencing trouble with the projector, follow these
steps to make sure everything is properly connected before you
call Technical Support for assistance.
Check cable connections. Verify that all computer, CableWiz-
1
ard and power cables are properly connected.
Verify that all power is sw itched on.
2
Verify that the projector is not in standby (the Standby LED on
3
the keypad is lit when the projector is in standby).
If the projector still doesn’t display an image, restart the com-
4
puter.
If the problem still exists, unplug the cable from the computer
5
NOTE: Macintosh computers
require a specific power-up
sequence: the projector must be
turned on before you turn on the
computer.
and check the computer monitor’s display. The maximum resolution that t h e projector can di s play is 1280x1024 pixels, pref erably 1024x768. The problem might be with the graphics
controller in your computer rather than with the projector.
When you reconnect the projector, remember to turn the computer and monitor off before you power up the projector.
Power the equipment back up in this order: projector, monitor,
computer .
40
If you’re using a laptop computer and it is not displaying your
6
presentation, make sure you have activated the computer’s
external video output. Most laptop computers do not automatically turn on their external video port when a secondary
display device such as a projector is connected. Refer to
page 51 for more information.
If the problem still exists, read through the problems and solu-
7
tions in this chapter.
Solutions to Common Problems
Problem: Nothing on projection screen
•
Make sure that the power cord is properly connected to a functional AC electrical outlet. Make sure that the power cord is
also properly connected to the projector and the green Power
LED is lit.
•
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 from the projection
lens at the front of the projector.
•
Make sure the projector is turned on.
•
Check the projector’s lamp to ensure that it is securely connected in the lamp module. See “Replacing the Projection
Lamp” on pa ge 37.
•
Make sure that the CableW izar d and the cables do not have any
bent pins. Check the power cord for bent pins also.
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 + or -” on page 22 for more
information.
•
Verify that the appropriate input source is selected. See “Computer” on page 22 or “Video” on page 23.
Problem: The screen resolution is not right
•
Make sure the computer’s graphics card is set for a resolution
of no greater than 1280x1024.
Problem: Image isn’t centered on the screen
•
Reposition the image. Refer to “Horizontal position” on
page 30 and “Vertical position” on page 30.
•
If you’re using an extension cable between the CableWizard
and the projector, make sure it’s In Focus-approved.
41
Maintenance & Troubleshooting
Problem: Only the start-up screen displays
•
Verify that the cables are connected correctly. Check to see that
the CableWizard computer cable is correctly connected to the
monitor connector on the computer (this is the connector
where your monitor cable usually goes.) See page 6 for con n ection procedures.
•
Verify that the proper input source is connected. See “Computer” on page 22 or “Video” on page 23.
•
You might need to turn everything off and power up the equipment again. Make sure you power up in this order: projector,
computer monitor, computer. It is especially important that
you follow this sequence for Macintosh computers.
•
Make sure your computer’s graphics board is installed and
configured 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.
42
Verify that the Display setting is 1280x1024 or less.
2
If you’re using Windows 95 or Windows 98:
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 1280x1024 or less.
3
Also check the following:
•
Does your computer have a compatible graphics board? The
projector isn’t CGA or EGA compatible.
•
Is your computer’s graphics board turned on? This is especially true for laptop computers. See “Portable and Laptop
Activation Chart” on page 51.
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 30.
•
Adjust the resolution of your monitor if it’s greater than
1280x1024. Only this resolution at 75 Hz or less will display on
the projector.
Problem: Image is out of focus
•
Turn the projection lens to focus the image.
•
Make sure the pr ojection scr een is at least 4 feet (1.2m) from the
projector.
•
Make sure the projector is turned off, then check the projection
lens to see if it needs cleaning.
Problem: Image and menus are reversed left to right
•
Rear projection mode is probably turned on. Switch back to forward projection from the Controls menu. The image should
immediately return to forward projection. See “Rear Projection” on page 32.
Problem: Image and menus are upside down
•
Ceiling mode is probably turned on. Turn off the mode from
the Controls menu. The image should immediately return to
forward projection. See “Ceiling Projection” on page 31.
Problem: the projector displays vertical lines, “bleeding” or spots
•
Adjust the brightness. See “Brightness + or -” on page 22.
•
Make sure the projector is turned off, then check the projection
lens to see if it needs cleaning.
Problem: no sound
•
Press the mute button.
•
Adjust volume.
•
Verify audio/input connections.
•
Adjust audio source.
43
Maintenance & Troubleshooting

Try these steps in this order.
Deactivate the screen saver on your computer.
1
2
Turn
Auto Image
off and then back on again. See “Auto
Image” on page 29.
Adjust the synchronization and tra c king manually to find an
3
optimal setting. See “Manual Sync” on page 29 and “Manual
Tracking” on page 30.
•
If you’re using an extension cable between the CableWizard
and the projector, make sure it’s In Focus-approved.
•
The problem could be with your computer’s graphics board. If
possible, connect a different computer.
Problem: Projected colors don’t match the computer or video
player’s col ors
•
Adjust the brightness, tint and/or contrast from the Display
menu. Just as there are differences in the displays of different
monitors, there are often differences between the computer
image and the projected image. See “Brightness + or -” on
page 22, “Tint” on page 25, and “Contrast” on page 25.
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 page37.
44
Problem: Lamp shuts off
•
A minor power surge may cause the lamp to shut off. Turn the
projector off, wait at least 30 seconds, then turn it back on.
Problem: Remote not operating correctly
•
You might need to replace the batteries. See “Replacing the Batteries in the Remote Control” on page 39.
•
Make sure you’re pointing the remote at the top of the projector, or at the projection screen.
•
Make sure the remote is within its operating range of 25 feet.
