source should not exceed 250 volts rms between the supply conductors or between either conductor and the ground.
iii
Safety Summary
Power Cord
Use only the power cord that was shipped with the projector.
Although other power cords might be similar in appearance, they
have not been safety-tested with the projector. Do not use a
power cord if it has become damaged or frayed. Contact your In
Focus dealer or call In Focus if you need to replace your power
cord.
Grounding
The projector is grounded through the grounding conductor on
the power cord. To avoid electric shock, plug the power cord into
a properly wired receptacle. Do not defeat the purpose of the
grounding-type plug.
Fuse
For continued protection against the risk of fire, use only the
specified fuse. It must be a time delay, high breaking capacity
5x20mm fuse with the following amperages: for 6.3amp use
T6.3AH, for 8amp use T8AH. Refer to page 42 for more information about fuse specifications a nd to pa ge 33 for instructions on
replacing the fuse.
Lamp
To avoid overheating and unacceptable image quality, replace the

Replacing the Projection Lamp
The lamp hour counter on the status bar at the top of the menus
counts the number of hours the lamp has been in use. The LP 225
uses 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 In Focus
dealer. See “Accessories” on page 43 for information.
Follow these steps to replace the projection lamp:
1 Turn off the projector and unplug the power cord.
2 Wait 45 minutes to allow it to cool thoroughly.
3 Using a small, flat-blade screwdriver, remove the screw on the
outside of the lamp door (Figure 22).
4 Pull the lamp cover up and remove it.
WARNING: To avoid burns,
allow the projector to cool for at
least 45 minutes before you open
the lamp module door. Never
extract the lamp module while the
lamp is operating.

counter was reset by pressing the menu button and viewing
the counter.
Replacing the Fuse
A power line surge or spike can blow the power supply fuse,
causing the projector to stop working. If this happens, you’ll need
to replace the fuse.
The projector ships with a 6.3 amp fuse. The correct replacement
fuse depends on the power line voltage in the country where you
are operating the projector.
•
If your line voltage is 115V to 240V, use a T6.3AH, 250V,
5x20mm fuse.
•
If your line voltage is 100V to 115V (as in Japan), use a T8AH,
250V, 5x20mm fuse. You can order the fuse from your In Focus
dealer; the part number is listed on page 44.
After you make sure that the condition that made the fuse blow
no longer exists, follow these steps to replace the fuse:
1 Turn off the projector by pressing the “O” side of the power
switch.
2 Unplug the power cord.
3 Remove the fuse holder, located just above the power cord
connector. Pull out the fuse holder with a small, flat-blade
screwdriver, key or coin (Figure 25).
CAUTION: Use only the specified power supply fuse. Using a different fuse may damage the
projector.
CAUTION: The 6.3A IEC 127
type fuse is required in Europe. In
countries with low main voltage,
you may need the 8.0A fuse to
avoid repeated (nuisance) blowing
of the 6.3A fuse. Both fuses provide protection from risk of fire. Do
not use the projector if repeated
blowing still occurs after switching
to the 8.0A fuse. Call In Focus
Technical Support for assistance.

puter and check the computer monitor’s display. The maximum resolution that the 225 can display is 1024x768 pixels,
preferably 800x600. 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.
36
6 If you’re using a laptop computer and its monitor is not dis-
playing your presentation, make sure you have re-activated
the computer’s monitor. Most laptop computers de-activate
their own monitor when a second display device, such as the
projector, is connected. Refer to page 45 for more information.
7 If the problem still exists, read through the problems and solu-
tions in this chapter.

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.

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
