EN-47 ENGLISH Maintenance Care of the projector Your projector needs maintenance from time to time, depending on the environmental circumstances, and should be done by authorized service technicians only. Contact your dealer for instructions. The only thing you can do yourselves on a regular basis is to keep the lens and cabinet 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. Never rub the lens with abrasive materials. Cleaning the projector case Before you clean the case, turn the projector off using the proper shutdown procedure as described in Shutting down the projector on page 33 and unplug the power cord. • To remove dirt or dust, wipe the case with a soft, lint-free cloth. • To remove stubborn dirt or stains, moisten a soft cloth with water and a neutral pH detergent. Then wipe the case. • Never use wax, alcohol, benzene, thinner or other chemical detergents. These can damage the case. • Flammable substances may ignite causing fire or breakdown while the lamp is illuminating. Storing the projector If you need to store the projector for an extended time, please follow the instructions below: • Make sure the temperature and humidity of the storage area are within the recommended range for the projector. Please refer to Specifications on page 55 or consult your dealer about the range. • Retract the adjuster feet. • Remove the battery from the remote control. • Pack the projector in its original packing or equivalent. Transporting the projector It is recommended that you ship the projector with its original packing or equivalent.
EN-48 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: EX321U: Total (equivalent) lamp hour = 1 (hours used in Low mode) + 10/7 (hours used in Standard mode) EX241U: Total (equivalent) lamp hour = 1 (hours used in Low mode) + 4/3 (hours used in Standard mode) See Setting Lamp mode as Low below for more information on Low mode. EX321U: The lamp hour in Low mode is calculated as 7/10 of that in Standard mode. That is, using the projector in Low mode helps to extend the lamp hour by 3/7. EX241U: The lamp hour in Low mode is calculated as 3/4 of that in Standard mode. That is, using the projector in Low mode helps to extend the lamp hour by 1/3. To obtain the lamp hour information: 1. Press MENU/EXIT and then press / until the SYSTEM SETUP: Advanced menu is highlighted. 2. Press to highlight Lamp Settings and press MODE/ENTER. The Lamp Settings page is displayed. 3. You will see the Equivalent lamp hour information appearing on the menu. 4. To leave the menu, press MENU/EXIT. You can also get the lamp hour information on the INFORMATION menu. Extending lamp life EX321U: The projection lamp is a consumable item that normally can last up to 3500 (used in Standard mode)-5000 (used in Low mode) hours with proper usage. Such interval differs depending on the operating environment and may be shorter than 3500-5000 hours. EX241U: The projection lamp is a consumable item that normally can last up to 3000 (used in Standard mode)-4000 (used in Low mode) hours with proper usage. Such interval differs depending on the operating environment and may be shorter than 3000-4000 hours. To keep the lamp life as long as possible, you can do the following settings via the OSD menu. Setting Lamp mode as Low Using Low mode reduces system noise and power consumption by 20%. If the Low mode is selected, the light output will be reduced and result in darker projected pictures. Setting the projector in Low mode also extends the lamp operation life. To set Low mode, go into the SYSTEM SETUP: Advanced > Lamp Settings > Lamp mode menu and press / . • When this mode is switched, the projected images may flicker. • If this mode is frequently switched, the lamp may be deteriorated. Setting Auto Power Off This function allows the projector to turn off automatically if no input source is detected and no operation is made by user after a set period of time to prevent unnecessary waste of lamp life. To s e t Auto Power Off, go into the SYSTEM SETUP: Basic > Auto Power Off menu and press / . The time period can be set from 5 to 30 minutes in 5-minute increments. If the preset time lengths are not suitable for your presentation, select Disable. The projector will not automatically shut down in a certain time period.
