Chem 150: Using the Projection Screen.

1. Obtain the keys.

The Chem 150 equipment key may be requested by departments or by faculty teaching in Chem 150.

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 cabinet doors.

AV equipment is located in the two rightmost sections of the instruction table as you face the class. Use the Chem 150 equipment key to unlock and open these doors.

3. Lower the screen.

The projection screen in Chem 150, is raised and lowered by an electric motor. To lower the screen, press the Down arrow button on the screen control switch. This switch is located in the top middle portion of the AV cabinet.

Press the button once and release it. The screen will automatically stop in the correct down position.

4. Turn on the projector.

To turn the projector ON, press the STANDBY/ON button.

5. Use the Computer and AV equipment.

6. Lower the shades and adjust the lighting.

The projector provides the best picture quality and brightness in a dark or dimly lit room. The window shades are lowered and raised by an electronic motor. The shades control switch is located in the top middle portion of the AV cabinet. Lower the switch to the down position.

Now adjust the lighting. The lighting control switches are located on the left wall of the room near both exits. You might want to experiment to find the best lighting option for your purposes. The left control panel has on/off switches for the overhead and front lecture lights. The right panel (front of the room only) controls the small round lights with an on/off button and sliding dimmer adjustment.

It is a good idea to adjust the lights after you have set up so you can see the controls better.

7. Restore the room lighting when you are finished.

Full room lighting can be restored by switching on the overhead and front lecture lights.

The shades control switch is located in the AV cabinet. Raise the switch to the up position.

8. Turn off the video projector.

To turn the projector OFF press the STANDBY / ON button approximately a second or two.

The lamp will turn off and be cooled. Then the unit will be completely shut off.
