Slide advancer and pointer are installed in all general classrooms and the USB connector is plugged directly into the back of the room computer and are NOT missing. There is a switch on the side to turn it off/on. Please leave in the classroom for your colleagues to use. One note though if you are recording your class the laser pointer does not show up in the recordings it is better to use the mouse and or pen attached to the monitor. Need to borrow one for a room not equipped? Contact this office.
