Troubleshooting
Your In-Wall Rear Projection SMART Board interactive whiteboard has light-emitting diodes
(LEDs) that communicate status information to you. Check these LEDs during your
troubleshooting investigation.
On the pen tray, a Ready light (LED) glows red when the pen tray has power, but is not active, and
green when the SMART Board driver is running (indicating that the pen tray is active). Each pen
tray tool has an LED above its slot. When you pick up a tool, the LED illuminates green, and when
you replace that tool, the LED stops glowing.
If you look behind the interactive screen, you’ll see two LEDs on the communications hub at the
bottom of the screen. One LED glows red to indicate that the screen is receiving power. The
second LED glows green when proper communication exists between the corner cameras and the
SC8 controller inside the pen tray.
If you encounter a problem with your screen, check all the cable connections. If this doesn’t solve
the problem, note the color of the LEDs described above, and then call Technical Support at the
numbers listed on page 59.
Touch Control or Electronic Ink Problems
If there are areas on the interactive whiteboard where your touch control is erratic or inaccurate, or
if there are areas where the electronic ink appears jagged or broken, you should orient the screen
(page 34) and calibrate the cameras (page 35).
