Evidence is previewed on a video monitor at the judge's bench. If the evidence is deemed to be admissible, the judge simply presses the "ENABLE" on this wireless touch screen. Video will then be sent to the witness monitor and to the video projector to be viewed by the entire courtroom. Pressing "DISABLE" will stop video from being sent to the witness monitor and the projector. Volume control and mute are also provided on this screen. The "PROJECTOR POWER" button displays a screen where the video projector power can be turned off or on. The "SETUP" button displays a screen where the touch screen's beep volume can be adjusted or disabled. Note: This touch screen will turn itself off after a period of inactivity to conserve battery power. Touch the screen anywhere to turn it back on. The touch screen is recharged by placing it in its base when not in use.
