Do not look into the laser light window or shine the laser light beam on yourself or others. See 
the warning messages on the back of the remote control prior to using it.
The laser pointer is not a toy. Parents should be mindful of the dangers of laser energy and 
keep this remote control out of the reach of children.

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 from among 1 to 8 in the SYSTEM SETTING: 
ADVANCED > Remote Control Code menu.
To switch the code for the remote control, press ID set and 
the number button corresponding to the remote control code 
set in the projector OSD together for 5 seconds or more. 
The initial code is set to 1. When the code is switched to 8, 
the remote control can control every projector.
If different codes are set on the projector and remote control, 
there will be no response from the remote control. When that 
happens, a messgae will display to remind you to switch the 
code for the remote control.
Using the remote mouse control
The capability of operating your computer with the remote control gives you more 
flexibility when delivering presentations. 
1. Take a USB cable and connect one end to the the Mini USB port on the projector and 
other end to your PC or notebook prior to using the remote control in place of your 
computer’s mouse. See Connecting a computer on page 18 for details.
2. Set the input signal to D-Sub / Comp..
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, press on the 
finger grip on the cover and pull it up in the direction of the arrow as illustrated.
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 pushing it back down into position. 
Stop when it clicks into place.
WARNING
• 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 drained 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 the following 4 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.

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.
