Possible operating states 
You may press the ON/OFF button (power button), or close the display panel (lid switch), or 
use the Windows Start menu to switch the PG from normal mode to one of the following 
operating states:  
●  Standby mode (Save to RAM),  
●  Hibernate (save to disk), default setting  
●  Off (Windows is brought down). 
When the device is brought down from Windows, the device automatically switches off. If the 
device is not in Windows, it can be switched off using the on/off button. 
 
 
Note 
You can use Settings > Control Panel > Power Options in Windows XP to assign a response 
to the on/off button and the lid. You can also assign these settings to the hot keys FN + F5 
and Fn + F6. 
 
 
Note 
In accordance with the settings in the Windows Power Options, the Field PG supports 
different operating states. The Power Options have been preset by the factory in such a way 
that in the factory state the device always adopts defined operating states (On, Standby, 
Hibernation, Off). 
By changing these settings, and by adding extra hardware (such as USB components) or 
software to the device, you can modify the operating states so that the device cannot switch 
to Hibernation or Standby mode. Even though the screen display is dark, relevant 
consumers remain switched on in the device. 
Please remember to always bring down the Field PG or set it to Hibernation prior to 
transporting in the backpack. When the device is in these states, all the status LEDs on the 
device go off when you disconnect the power supply. This way you can ensure the device is 
not switched on and the battery is not unintentionally discharged during transportation. 
 
Press the on/off button briefly to reactivate the PG from Standby mode or Hibernation. In 
Standby mode the device LED flashes, and in Hibernation all the displays are switched off.
