If the LED core flashes red, it means the device has received an error message. There are 2 main causes of an input error.
  1. No Body Sensed: If the device does not sense your body through one of the sensors, the light will flash red. Move closer to the device to resolve.
  2. Timeout: If you do not enter trick inputs fast enough, the device will time out. Try to enter the inputs faster to resolve.
