Replacing the lithium battery
In order to permanently save the system information, a lithium battery is installed to provide
the CMOS-memory with a current. A corresponding error message noti
fi es the user when the
charge is too low or the battery is empty. The lithium battery must then be replaced.
For 0-Watt devices: As an interim solution, the device can be started using the
emergency on button at the rear, see chapter
"Switching on a device when the
lithium battery is discharged (0-Watt devices)", Page 22 .
