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 8 meters (~ 26 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 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.
Obtaining a preferred projected image size The distance from the projector lens to the screen, the zoom setting (if available), and the video format each factors in the projected image size. 4:3 is the native aspect ratio of this projector. 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 in mm" value.
Projection dimensions Refer to "Dimensions" on page 58 for the center of lens dimensions of this projector before calculating the appropriate position.

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. Never remove any parts of the projector except the lamp. Contact your dealer if other parts need replacing. Cleaning the lens Clean the lens whenever you notice dirt or dust on the surface. • • Use a canister of compressed air to remove dust.
Lamp information Getting to know the 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 = 1 (hours used in Economic mode) + 4/3 (hours used in normal mode) See "Setting Lamp mode as Economic" below for more information on Economic mode. The lamp hour in Economic mode is calculated as 3/4 of that in Normal mode.
Timing of replacing the lamp When the Lamp indicator lights up red or a message appears suggesting it is time to replace the lamp, please install a new lamp or consult your dealer. An old lamp may cause a malfunction in the projector and in some instances the lamp may explode. The Lamp indicator light and Temperature warning light will light up if the lamp becomes too hot. Turn the power off and let the projector cool for 45 minutes.
Replacing the lamp • If lamp replacement is performed while the projector is suspended upside-down from the ceiling, make sure that no one is underneath the lamp socket to avoid any possible injury or damage to the human eyes caused by fractured lamp. • To reduce the risk of electrical shock, always turn the projector off and disconnect the power cord before changing the lamp. • To reduce the risk of severe burns, allow the projector to cool for at least 45 minutes before replacing the lamp.
5. 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.
11. Restart the projector. Do not turn the power on with the lamp cover removed. Resetting the lamp timer 12. After the startup logo, open the On-Screen Notice Display (OSD) menu. Go to the SYSTEM Reset Lamp Timer? SETUP: Advanced > Lamp Settings menu. Press Mode/Enter. The Lamp Settings page Reset Cancel displays. Press to highlight Reset lamp timer and press Mode/Enter. A warning message displays asking if you want to reset the lamp timer. Highlight Reset and press Mode/Enter.
