CHAPTER 5 – TROUBLESHOOTING YOUR SMART BOARD INTERACTIVE 
WHITEBOARD

Flowchart 5: Ready Light Steady Green

When 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.
