3.6.4.3 Error Handling

The wireless updater is designed to be fail safe. The radio protocol contains limited error handling due to

its small footprint, but the updater provides recovery if the update process fails. Upon communication

failures, the watch 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.
