Using the remote control for the first time Pull the tab before using the remote control. Remote control effective range Infra-Red (IR) remote control sensor is located on the front of the projector. The remote control must be held at an angle within 30 degrees perpendicular to the projector's IR remote control sensor to function correctly. The distance between the remote control and the sensor should not exceed 8 meters (~ 26 feet).
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 possible installation locations: 1. Front Table 3.
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 EX321U-ST. 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. This will result in a proportionally smaller height equivalent to 75% of the projector's native aspect height.
1. 2. 3. 4. 5. Determine the aspect ratio of your screen, 16:9 or 4:3. If you have a 4:3 screen, refer to the table labeled "(Standard)". If you have a 16:9 screen, refer to the table labeled "(16:9)". Select your screen size. Refer to the table and find the closest match to your screen size in the left columns labeled "Screen". Using this value, look across this row to the right to find the corresponding average distance from screen value in the column labeled "Distance from the screen: L".

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. If there is dirt or smears, use lens-cleaning paper or moisten a soft cloth with lens cleaner and gently wipe the lens surface.
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 Low mode) + 10/7 (hours used in Standard mode) See "Setting Lamp mode as Low" below for more information on Low mode. The lamp hour in Low mode is calculated as 7/10 of that in Standard mode.
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 indicator 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 Spare lamp for EX321U-ST/EW331U-ST: VLT-EX320LP • Be sure to replace the lamp with a new lamp separately sold that is exclusive to this projector. Contact your dealer for purchase of the 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.
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. If you touch the optical components inside, it could cause color unevenness and distortion of the projected images.
• • EN-52 Do not reset if the lamp is not new or replaced as this could cause damage. This projector uses a lamp that contains mercury. Disposal of the lamp or the projector with the lamp may be regulated due to environmental considerations. For disposal or recycling information, please contact your local authorities or the Electronic Industries Alliance: www.eiae.org. (For US only).
