Maintenance 53 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. • 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 45 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. 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 61 or consult your dealer about the range. • Retract the adjuster feet. • Remove the batteries 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. When you carry the projector yourself, please use the original box or provided soft carry case.
Maintenance 54 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. That is, using the projector in Economic 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 displays. 4. You will see the Equivalent Lamp Hour information displaying on the menu. 5. To leave the menu, press MENU/EXIT. You can also get the lamp hour information on the INFORMATION menu. Extending lamp life The projection lamp is a consumable item that normally can last up to 3000-4000 hours with proper usage. To keep the lamp life as long as possible, you can do the following settings via the OSD menu. • Setting Lamp Mode as Economic Using Economic mode reduces system noise and power consumption by 20%. If the Economic mode is selected, the light output will be reduced and result in darker projected pictures. Setting the projector in Economic mode also extends the lamp operation life. To set Economic mode, go into the SYSTEM SETUP: Advanced > Lamp Settings > Lamp Mode menu and press / . • Setting Auto Power Off This function allows the projector to turn off automatically if no input source is detected 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.
