Most teachers love their Promethean boards and find uses for them throughout the day. The bulbs in projectors are expensive and there are ways you can promote their longevity.
Be sure to clean the two filters on your orange projector at least monthly to ensure the proper amount of air is being circulated through the projector for cooling. Your ITRT can show you how to access the two areas on the projector that require this regular maintenance.
When not using the projector for extended periods of time, turn the projector off. “Extended” periods would be 25 minutes or longer.
If you’re projecting in a dark environment without window or overhead light, consider running the projector in a reduced-brightness mode. This may be toggled through the remote. See your ITRT for details. If you run the projector in “Auto Brightness” mode, it will automatically choose the setting by using the projector’s ambient light sensor.
