Extron Instructions (pre 2012)
1. This is the ON/OFF buttons for the Projector, when the projector is in a “warm up” or “cool down” mode these lights will flash on and off indicating the projector is in the process of either turning on or shutting off and cannot be accessed by the panel, this will typically last for 10-30 seconds. Once the light on the button is solid you may continue.
2. These buttons are your “Source Selection” buttons, these allow you to select between your DVD/VCR and your Computer (PC) as a video source. The VCR and DVD button both point to the same device because we use combo DVD/VCR units in all our classrooms so either button will work. MUTE button not available with our systems
3. Volume control knob, the red and green LEDs indicate the volume level, red being the max level output.
4. This is a configuration port that is not used by the end user it allows River City to configure the wall plate to work with our projectors and sound systems.
