The wireless update software is designed to be fail safe. The radio protocol contains limited error handling due to its small footprint, but the update software provides recovery if the update process fails. Upon communication failures, the Chronos module is put in low-power mode (LPM4) and the LCD is turned off. The update process can be restarted by pushing the DOWN button after the update process is restarted on the PC.
