Turning Off the FTB-500
There are several ways to turn off the unit, including the following:

Standby: keeps the unit’s status information in memory (RAM). The
next time you turn your unit on, you will quickly return to your work
environment (running applications will still be running).This mode will
take more battery power while the unit is off.

Hibernation: saves the unit’s status information that was in memory
(RAM) to a special file on the disk. The next time you turn your unit on,
this file will be used to ensure that you return to your work
environment (running applications will still be running). The unit will
take longer to start up than in Standby mode, but it requires less battery
power when the unit is off. You can configure your unit to switch
automatically from Standby to Hibernation mode after the specified
delay.

Shutdown: completely cuts power to the test modules and platform;
the unit will perform a complete restart routine the next time you use
it. You should perform a shutdown if you do not intend to use your unit
for a week or more.
After a shutdown, the unit will start in Toolbox or in the application you
defined as the startup application.
Note: Should the unit ever stop responding, you can force a hardware reset by
pressing and holding down the power button for more than 10 seconds.
By default, your unit will display the standard shutdown window from
which you can select the desired shutdown mode. However, you can
configure your unit to perform a different action when the power button is
pressed.
You can also configure your unit to automatically restart when AC power
comes back after the unit has turned off (emergency shutdown, standby,
or hibernation modes) when battery level is too low.
