Power Up
The following diagram shows the respective TD7
AdaptiView™ screens during a power up of the Symbio
800 and display. This process takes 15 seconds for the
Symbio 800, and 105 seconds for the display. On all power
ups, the software model always will transition through the
'Stopped' Software state independent of the last mode. If
the last mode before power down was 'Auto', the
transition from 'Stopped' to 'Starting' occurs, but it is not
apparent to the user.
