The robot's LED doesn't light up

If the LED does not light up, either after sending a relevant code or in test mode, please try the following:

1. Verify that power is coming through to the Core from the battery box.
Please click here for instructions.

2. In the Robot Recipes or the Learning Course, if the connecting port is displayed, verify that it is connected in the right location.

3. If the previous actions did not yield results, some electronic parts may be damaged. Please verify whether or not that's the case using the Troubleshooting mode. Also, please pay particular attention to such problems happening when the only source of power is the USB cable.

If these steps do not yield results, please inquire at customer service at the phone number at the bottom of this page.
