Remote control effective range Infra-Red (IR) remote control sensors are located on the front and the back of the projector. The remote control must be held at an angle within 30 degrees perpendicular to the projector's IR remote control sensors to function correctly. The distance between the remote control and the sensors should not exceed 6 meters (~ 20 feet). Make sure that there are no obstacles between the remote control and the IR sensors on the projector that might obstruct the infra-red beam.
Positioning your projector Choosing a location Your projector is designed to be installed in one of four possible installation locations: 1. Table in front of screen; 2. Ceiling in front of screen; 3. Table at rear of screen; 4. Ceiling at rear of screen. 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.
If you use the projector with wireless function, there's no need to worry about data cable connections.This gives you the flexibility to site the projector anywhere in the room up to a range of 20m away from your notebook, and switch between presentations on different notebooks instantly without fiddling with cables To use the wireless function, you need to install a BenQ wireless module to the projector and enable your notebook/desktop PC with wireless connection.
Obtaining a preferred projected image size The distance from the projector lens to the screen, the zoom setting, and the video format each factors in the projected image size. The maximum (native) resolution of the projector is 1024 x 768 pixels, which is a 4 to 3 aspect ratio (expressed as 4:3). To be able to project a complete 16:9 (widescreen) aspect ratio image, the projector can resize and scale a widescreen image to the projector's native aspect width.
How to determine the position of the projector for a given screen size 1. 2. Select your screen size. Refer to the table and find the closest match to your screen size in the left columns labelled '4:3 Screen Diagonal'. Using this value, look across this row to the right to find the corresponding average distance from screen value in the column labelled 'Average'. This is the projection distance. 3. On that same row, look across to the right column and make note of the vertical Offset value.
Projection dimensions Refer to "Dimensions" on page 66 for the center of lens dimensions of this projector before calculating the appropriate position.
Connection When connecting a signal source to the projector, be sure to: 1. Turn all equipment off before making any connections. 2. Use the correct signal cables for each source. 3.

To connect the projector to an composite Video source device: 1. Take the Video cable and connect one end to the composite Video output socket of the Video source device. 2.
Operation Start up 1. Plug the power cord into the projector and into a wall socket. Turn on the wall socket switch (where fitted). Check that the Power indicator on the projector lights orange after power has been applied. 2. Remove the lens cap. If it is left on, it could become deformed due to the heat produced by the projection lamp. 3. Press and hold (for 2 seconds) II Power on the projector or remote control to start the projector.
Utilizing the password function For security purposes and to help prevent unauthorized use, the projector includes an option for setting up password security. The password can be set through the On-Screen Display (OSD) menu. For details of the OSD menu operation, please refer to "Using the menus" on page 46. WARNING: You will be inconvenienced if you activate the password functionality and subsequently forget the password.

Maintenance Care of the projector Your projector needs little maintenance. The only thing you need to do on a regular basis is to keep the lens clean and to clean the dust filter to prevent overheating. See "Cleaning the lens" and "Cleaning and replacing the dust filter" below for details. Never remove any parts of the projector except the lamp and dust filter. Contact your dealer if other parts need replacing. Cleaning the lens Clean the lens whenever you notice dirt or dust on the surface.
A warning message like the one pictured to the right will be displayed for 10 seconds every 500 hours of use to remind you to clean the filter. To leave the message, press ENTER on the projector or remote control. Clean the Air Filter The air filter should be cleaned every 500 hours of use. If you have not done so, please clean or replace the filter. OK To clean the filter 1. 2. Turn the projector off and wait until the fans stop running. Locate the filter case on the back of the projector.
6. 7. 8. Refit the filter case by aligning and inserting it into the projector slot. Press the case back until it clicks into place. Turn the projector back on. If the case is not correctly seated in place, the projector will display an on-screen message as pictured to the right every three minutes. WARNING The message will display 3 times for a 10-second duration each, if no further action is taken. Check the Air Filter The air filter is not installed well. Please reinstall again.
Lamp information Calculation of lamp hour When the projector is in operation, the duration (in hours) of lamp usage is automatically calculated by the built-in timer. The method of calculating the equivalent lamp hour is as follows: Total (equivalent) lamp hour = 3/4 (hours used in Economic mode) +1 (hours used in normal mode) See "Lamp Mode (Normal)" on page 51 for more information on Economic mode. The lamp hour in Economic mode is calculated as 3/4 of that in normal mode.
Out of Lamp Usage Time The projector will be shut down automatically for safety issue. Please replace the lamp as soon as possible. If this warning message displays, the projector will shut down in 40 seconds. The lamp MUST be replaced before the projector will operate normally. Replacing the lamp • To reduce the risk of electrical shock, always turn the projector off and disconnect the power cord before changing the lamp.
4. Disconnect the lamp connector from the projector. 5. Loosen the screw that secures the lamp. 6. Lift the handle so that it stands up. Use the handle to slowly pull the lamp out of the projector. • Pulling it too quickly may cause the lamp to break and scatter broken glass in the projector. • Do not place the lamp in locations where water might splash on it, children can reach it, or near flammable materials. • Do not insert your hands into the projector after the lamp is removed.
9. Tighten the screw that secures the lamp. • Loose screw may cause a bad connection, which could result in malfunction. • Do not over tighten the screw. 10. Ensure the handle is fully laid flat and locked in place. 11. Replace the lamp cover on the projector. 12. Tighten the screw that secures the lamp cover. • Loose screw may cause a bad connection, which could result in malfunction. • Do not over tighten the screw. 13. Restart the projector.
