Usage Guidel ines
•
Do not look directly into the projection lens when the lamp 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.
•
Transport the projector in a vendor-approved hard or soft case.
Part numbers for these cases are listed on page 41.

Setting up the Projector
Connecting a Video Player
The LP770 has 3 different connections for video players: S-video,
composite video, and BNC (the S-video and BNC connections
require cables not included with the LP770).
If your video player uses a round, one-prong composite video
1
connector, plug the composite video cable’s yellow connector
into the “video-out” connector on your video player. This connector may be labeled “To Monitor.” If you’re using an Svideo cable, connect it to the “S-video out” connector on the
video player. If you’re using a BNC cable, connect it to the
“BNC-video out” connector on the video player (Figure 9).
CAUTION: Your video player
may also have a “Video Out”
connector for a coaxial cable
connection. DO NOT use this to
connect to the projector.
Plug the other yellow connector into the
2
Video 2 In
composite
video connector on the projector. If you’re using S-video, plug
the other end of the cable into the
Video 1 or 2 In
“S-video”
connector on the projector. If you’re using BNC, plug the other
end of the cable into the
Video 1 In
“BNC” connector on the
projector.

connector on the projector; plug the audio cable’s red connector into the Right Audio connector on the projector.
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. See “Video Signal” on page 26 for details.
Connecting DVD players with component video output or HDTV
decoders
If your DVD player has (Y,Cb,Cr) outputs, use the Computer 1 or
Computer 2 In connectors. Also select (Y,Cb,Cr) for Computer
Input in the Signal menu (see “Computer Input” on page 28).
If your HDTV decoder has (Y,Pb,Pr) outputs, use the Computer 1
or Computer 2 In connectors. Also select (Y,Pb,Pr) for Computer
Input in the Signal menu.
If your HDTV decoder has R, G, B output, select RGB for Computer Input in the Signal menu.

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 11).
If the image doesn’t display completely, adjust the height and
2
tilt of the projector (page 15), zoom the image (page 15), or
center the image by adjusting its horizontal or vertical position (page 27).
If the image is out of focus, use the
3
Zoom/Focus
button on the
remote or keypad to focus it (page 15).
If the computer image appears to shimmer or if it has blurry
4
vertical bars after you have adjusted the focus, press the
Position
button on the remote or keypad (page 17). If the
Auto
image still doesn’t look right, adjust the fine sync (page 27)
and/or the tracking (page 28) manually.
If the colors don’t look right, adjust the brightness (page 21)
5
and tint (page 22).
Using the Remote Control
Point the remote control at the projection screen or at the front or
the rear 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 16 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 10).
NO TE: If you can’t aim the
remote control at the projector so
that its signal is received — for
example, when using rear projection — use the remote control
cable to connect the remote
directly to the projector.

MAINTENANCE & TROUBLESHOOTING
This section describes how to:
•
clean the lens
•
clean the air filters
•
replace the projection lamp
•
replace the batteries in the remote
•
use the Kensington lock feature
•

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.
•
Abrasive cleaners, solvents or other harsh chemicals might
scratch the lens.
Lightly wipe the cleaning cloth over the lens in a circular
2
motion.
If you don’t intend to use the projector immediately, replace
3
the lens cap.
Cleaning the Air Filters
The projector has two air filters, located on the bottom of the projector, that prevent dust and particles in the air from entering the
projector . The larg er filter is flexible mesh, the smaller one is rigid
metal mesh.
If the filters becomes clogged, the projector does not cool properly and may malfunction. To prevent this, clean the filters after
every 100 hours of use. Note that the filters are cleaned differently.
Turn off the power and unplug the power cord.

Replacing the Projection Lamp
The average life of the lamp is 2,000 hours. When the lamp has
been in use for 1,500 hours, the lamp LED alternately blinks
green and red. After 1,900 hours, the word “LAMP!” appears on
the screen for one minute. After 2,000 hours, the lamp shuts off
automatically. The projector cannot be used until you replace the
lamp and reset the lamp timer. You can order new lamp modules
from your InFocus dealer. See “Accessories” on page 40 for information.
Follow these steps to replace the projection lamp:
Turn off the projector and unplug the power cord.

the lamp module door. Never
extract the lamp module while the
lamp is operating.
CAUTION: Never operate the
projector with the lamp door open

Appendix
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 info rmation 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, then 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.
