What to keep in mind during mains operation
Risk of fire and electric shock
The On/Off button does not completely isolate the device from the power supply. If the
device is switched off with the On/Off button, there is still a risk of electric shock and fire,
for example, if the device or the connection cables are damaged, or in the event of
improper use.
When working on the device or if the device is not used for a long period of time, always
disconnect it fully from the power supply. Shut down the operating system and if you are
using the device in mains operation, pull out the power plug.
