Sudden reboot
In case EmbracePlus self-reboots, you will see a dark
display with 'HI!' for a few seconds. EmbracePlus
self-reboots to restore proper functioning in cases of
unexpected behavior.
During this brief interval, data recording will stop.
Once recording resumes, the display background will
turn light again and the time will be shown. Data
synchronization will be automatic and no further
action is required.
