Press the Power on/power off button to turn the device on or off. Upon each power up, the
display lights up and the ProBP 3400 displays the model number. When the internal self-check
completes, the display shows the Home screen with all values blank, and the device is ready for
operation.
If disconnected from an external power source, the ProBP 3400 automatically powers off when not
used for 30 minutes. When the device is connected to external power, the device will automatically
power off after three hours of non-use.

and a system fault code to assist service and engineers in diagnosing the problem.
