LSci 175: Using the Projection Screen.

1. Obtain the keys.

The LSci 175 equipment cabinet key may be requested by departments or by faculty teaching in this room.

Classroom keys and building master keys do not open these locks. Departments with faculty or staff needing access to the AV /computer equipment may want to have a key in their department office available for checkout. Or faculty and staff who make frequent use of classroom equipment may want to request a key for their personal use. In either case, a key request card must be completed, signed by the Dean or Department Head, and delivered to Facilities Management Key Shop. "AV Cabinets" must be printed at the top of the card to specify that the requested key is for the equipment cabinet and not for the room itself. A separate key request card for the room must be completed to obtain a room key.

2. Unlock and open the equipment cabinet doors.

The projector controls and other equipment are located in the equipment cabinet at the front of the room. This cabinet has four locks. Use the equipment cabinet key to unlock them.

Then open the doors.

3. Lower the screen.

The projection screen is raised and lowered by an electric motor. The screen control switch is at the front left side of the room as you face the class. It is half visible and tucked away inside the crack in the wall between the audio amplifier and the lighting controls.

Lower the switch to the DOWN position.

The screen will automatically stop in the correct down position.
