Startup Options

Power up Immediately 

Raspberry Pi will power up automatically as 
soon as the it receives power from  
SmartUPS.

Power up on Battery Stable Raspberry Pi will power up automatically when 

the battery status becomes stable.

Power up on Battery Full

Raspberry Pi will power up automatically when 
the battery is fully charged.

No Auto Power up

Raspberry Pi will not power up automatically

Shutdown Options

Shutdown Time

Raspberry Pi will shutdown automatically after 
a user defined time once the main power is 
disconnected from the SmartUPS. A value of 
0 (zero) will not shutdown the Raspberry Pi 
until the battery status reaches 'Critical'.  

Verbose

The SmartUPS will display a message through 
command prompt every minute of the 
shutdown process

Quiet

The SmartUPS will not display messages 
during the shutdown process
