The Display Source button lets you switch between three input devices for video and audio 
input, and control over the interactive whiteboard. You’ll know which is the current source from 
the Active Display Source LED.

Refer to Table 3 for details on using the Display Source button. This table assumes that 
you’ve connected the internal computer and the laptop to the provided cable bundles, and the 
S-video source to the connection panel.

NOTE: Don’t press the Display Source button too quickly. Instead, wait until the source 
displays before pressing the button again.

If your Computer 1 source is connected with BNC connectors (not supplied), you can change 
Source 1 to the BNC setting by holding all three Down buttons for three seconds. To change 
Source 1 back to the 15-pin connector, hold the three Up buttons for three seconds.
