LCD Projector

All projectors are not alike.  If these answers don’t work for your particular projector, you should direct your questions to the TIS or the media specialist at your school.

What do I do if the sound is too low to be heard in the classroom?

You will need to attach speakers to your computer if your school does not have an audio system in the classrooms.

How do I turn the projector off?

Push the power button on top of the projector.  A message on the screen will ask if you want the power off.  Press once for yes.  The fan will run to cool the projector bulb.  Once the fan is off, then the power switch on the side of the projector may be turned off and the projector unplugged.

Do I need to let the bulb cool before I turn off the projector?

Yes.  Cooling extends the bulb life.  Each bulb costs about $350.
