Soft power key
The soft power key can trigger two shutdown functions during active operation:
•
Correct shutdown of the operating system and shutdown of the device
To perform this function, press the key briefly with a pointed object.
•
Immediate switch-off of the device without correct shutdown of the operating system
This function is used to shut down the device when it no longer responds. Press the key
for approximately 4 seconds with a pointed object
Caution
Data loss
Although this function does not trigger a hardware reset, loss of data cannot be ruled out
as a result.
Then you can start the device again in one of two ways:
•
Restart via soft power key
If you wait at least 7 s after shutdown and then press the key, the device will boot again.
•
Restart via On/Off switch
After shutdown, place the On/Off switch in Position 0 and wait for at least 7 s. Then, when
you place the On/Off switch in Position 1, the device will boot up again.
