Solution

You can check the status of the CPU LED after powering on the device, the LED should blink red & green for a few seconds then :
  • if the LED turns off, contact the technical support for alternative solutions
  • if the LED turns on red, apply the following procedure :
  1. At power-up, just after the main status led blinks red/green and just before the initialization time during which one the led stays red for a second, press the abort A push-button until the main status led becomes orange.
  2. Release the abort A push-button, the main status led should stay red. Repeat this step several time to be successful
  3. Launch MPUpdate software and select the correct *.dat file for the firmware used by the MP300 .
