46 | CHAPTER 5 – TROUBLESHOOTING YOUR SMART BOARD INTERACTIVE
WHITEBOARD
Flowchart 5: Ready Light Steady GreenWhen you disconnect and reconnect the USB cable
to reset the power as described in Resetting Your
Interactive Whiteboard on page 41, all of the pen tray
LEDs flash sequentially twice, indicating successful
communication with the controller. If they flash
continuously, contact your next level of support.
A solid green Ready light indicates that the controller
is operating normally. If the pen tray failed or isn’t
communicating with the controller, your interactive
whiteboard still operates in mouse mode.
• Check that the tools are placed properly in their
pen tray recesses.
• Obstructed or dirty infrared (IR) sensors in the
pen tray recesses can prevent the detection of
pen or eraser removal.
• Remove any obstructions, and then clean the
infrared sensors with a cotton swab and glass
cleaner.
• If a sensor or the pen tray has failed, contact
your next level of support.
NOTE
If another user has reassigned the pen, eraser or pen tray button functions, you
can return them to normal operation using the SMART control panel.
