Remote control code
The projector can be assigned to two different remote control codes, A or B. When several 
adjacent projectors are in operation at the same time, switching the remote control codes 
can prevent interference from other remote controls. Set the remote control code for the 
projector first before changing that for the remote control.
To switch the code for the projector, select A or B in the SYSTEM SETTING: 
ADVANCED > Remote Control Code menu.
To switch the code for the remote control, press PgUp and PgDn buttons on the remote 
control together for 5 seconds or more. The initial code is set to A.
If different codes are set on the projector and remote control, there will be no response from 
the remote control. When that happens, switch the code for the remote control again.

remote control in place of your computer’s mouse. See Connecting a computer on 
page 15 for details.
2. Set the input signal to D-Sub / Comp. 1, D-Sub / Comp. 2.
3. Press Mouse on the remote control to switch from the normal mode to the mouse 
mode. An icon appears on the screen to indicate the activation of the mouse mode.
4. Perform the desired mouse controls on your remote control.
• To move the cursor on the screen, press  / / / . 
• To left-click, press  . 
• To right-click, press  . 
• To operate your display software program (on a connected PC) which responds to 
page up/down commands (like Microsoft PowerPoint), press PgUp/PgDn.
• To return to the normal mode, press Mouse again or other keys except for the 
mouse related multi-function keys.
Remote control effective range
The Infra-Red (IR) remote control is located on the front 
of the projector. The remote control must be held at an 
angle within 30 degrees perpendicular to the projectors 
IR remote control sensor to function correctly. The 
distance between the remote control and the sensor should 
not exceed 8 meters (~ 26 feet).
Make sure that there are no obstacles between the remote 
control and the IR sensor on the projector that might 
obstruct the infra-red beam.

Replacing the remote control batteries
1. To open the battery cover, turn the remote control over to view its back, push on the 
finger grip on the cover and slide it in the direction of the arrow as illustrated. The 
cover will slide off.
2. Remove any existing batteries (if necessary) and install two AAA batteries observing 
the battery polarities as indicated in the base of the battery compartment. Positive (+) 
goes to positive and negative (-) goes to negative.
3. Refit the cover by aligning it with the base and sliding it back down into position. 
Stop when it clicks into place.
• Avoid leaving the remote control and batteries in an excessive heat or humid environment 
like the kitchen, bathroom, sauna, sunroom or in a closed car.
• Replace only with the same or equivalent type recommended by the battery manufacturer.
• Dispose of the used batteries according to the manufacturers instructions and local 
environment regulations for your region.
• Never throw the batteries into a fire. There may be danger of an explosion.
• If the batteries are dead or if you will not be using the remote control for an extended 
period of time, remove the batteries to avoid damage to the remote control from possible 
battery leakage.

Positioning your projector
Choosing a location
Your room layout or personal preference will dictate which installation location you select. 
Take into consideration the size and position of your screen, the location of a suitable power 
outlet, as well as the location and distance between the projector and the rest of your 
equipment.
Your projector is designed to be installed in one of four possible installation locations:
1. Front Table
Select this location with the projector placed near 
the floor in front of the screen. This is the most 
common way to position the projector for quick 
setup and portability.
2. Front Ceiling
Select this location with the projector suspended 
upside-down from the ceiling in front of the 
screen.
Purchase the projector ceiling mount kit from your 
dealer to mount your projector on the ceiling.
Set Front Ceiling in the SYSTEM SETTING: 
BASIC > Projector Position menu after you turn 
the projector on.
3. Rear Ceiling
Select this location with the projector suspended 
upside-down from the ceiling behind the screen.
Note that a special rear projection screen and the 
projector ceiling mounting kit are required for this 
installation location.
Set Rear Ceiling in the SYSTEM SETTING: 
BASIC > Projector Position menu after you turn 
the projector on.
4. Rear Table
Select this location with the projector placed near 
the floor behind the screen.
Note that a special rear projection screen is 
required.
Set Rear Table in the SYSTEM SETTING: 
BASIC > Projector Position menu after you turn 
the projector on.

Projection dimensions
Refer to Dimensions on page 58 for the center of lens dimensions of this projector before 
calculating the appropriate position.
The screen mentioned below refers to the projection screen usually consisting of a surface 
and a support structure
There is 3% tolerance among these numbers due to optical component variations. It is 
recommended that if you intend to permanently install the projector, you should physically 
test the projection size and distance using the actual projector in situ before you permanently 
install it, so as to make allowance for this projectors optical characteristics. This will help you 
determine the exact mounting position so that it best suits your installation location.

Connecting a computer or monitor
Connecting a computer
The projector provides two VGA input sockets that allow you to connect them to both 
IBM® compatibles and Macintosh® computers. A Mac adapter is needed if you are 
connecting legacy version Macintosh computers.
To connect the projector to a notebook or desktop computer:
1. Take the supplied VGA cable and connect one end to the D-Sub output socket of the 
computer.
2. Connect the other end of the VGA cable to the COMPUTER IN 1 or COMPUTER 
IN 2 signal input socket on the projector.
3. If you wish to use the remote paging function, take a USB cable and connect the 
larger end to the USB port of the computer, and smaller end to the MINI USB socket 
on the projector. See Using the remote mouse control on page 10 for details.
Many notebooks do not turn on their external video ports when connected to a projector. 
Usually a key combo like FN + F3 or CRT/LCD key turns the external display on/off. Locate a 
function key labeled CRT/LCD or a function key with a monitor symbol on the notebook. Press 
FN and the labeled function key simultaneously. Refer to your notebooks documentation to 
find your notebooks key combination.
Connecting a monitor
If you want to view your presentation close-up on a monitor as well as on the screen, you 
can connect the MONITOR OUT signal output socket on the projector to an external 
monitor with a VGA cable following the instructions below:
To connect the projector to a monitor:
1. Connect the projector to a computer as described in Connecting a computer on page 
15.
2. Take a suitable VGA cable (only one supplied) and connect one end of the cable to the 
D-Sub input socket of the video monitor. 
Or if your monitor is equipped with a DVI input socket, take a VGA to DVI-A cable 
and connect the DVI end of the cable to the DVI input socket of the video monitor.
3. Connect the other end of the cable to the MONITOR OUT socket on the projector.
• The MONITOR OUT output only works when COMPUTER IN 1 connection is made to the 
projector.
• To use this connection method when the projector is in standby mode, turn on the Active 
VGA Out function under the SYSTEM SETTING: BASIC > Standby Settings menu.
