Important notes
Store this manual close to the device. If you pass on the device to third parties, you should also
pass on this manual.
!Be sure to read this page carefully and note the information before you open the PC.
You cannot access the components of the system board without first opening the device.
How to dismantle and reassemble the device is described in the Operating Manual
accompanying the device.
Please note the information provided in the chapter "Safety" in the Operating Manual of
the PC.
Incorrect replacement of the lithium battery may lead to a risk of explosion. It is therefore
essential to observe the instructions in the chapter „Add-on modules“ - „Replacing the
lithium battery“.
The lithium battery must be replaced with an identical battery or a battery type
recommended by the manufacturer (CR2032).
Do not throw lithium batteries into the trashcan. It must be disposed of in accordance with
local regulations concerning special waste.
The shipped version of this board complies with the requirements of the EEC
directive 89/336/EEC "Electromagnetic compatibility".
Compliance was tested in a typical PC configuration.
When installing the board, refer to the specific installation information in the
Operating Manual or Technical Manual of the receiving device.
Connecting cables for peripherals must be adequately insulated to avoid interference.
!Components can become very hot during operation. Make sure you do not touch
components when making extensions to the system board. There is a danger of burns!
iThe warranty expires if the device is damaged during the installation or replacement of
system expansions. Information on which system expansions you can use is available
from your sales office or the customer service.

Boards with electrostatic sensitive devices (ESD) may be identified by labels.
When you handle boards fitted with ESDs, you must observe the following points under all
circumstances:
• You must always discharge yourself (e.g. by touching a grounded object) before working.
• The equipment and tools you use must be free of static charges.
• Pull out the power plug before inserting or pulling out boards containing ESDs.
• Always hold boards with ESDs by their edges.
• Never touch pins or conductors on boards fitted with ESDs.

Recovering System BIOS - switch 5
Switch 5 enables recovery of the old system BIOS after an attempt to update has failed. Memory
bank 1 must be populated in order to be able to restore the system BIOS. To restore the old BIOS
you need a Flash BIOS Diskette (call customer service).
on The System BIOS executes from floppy drive A: and restores the System BIOS on
the system board.
off The System BIOS is started from the system board (default setting).
Write protection for floppy disk drive - switch 8
Switch 8 is used to define whether floppy disks can be written or deleted in the floppy disk drive. To
write and delete floppy disks, the write protection in BIOS setup must be disabled (in menu Security,
the field Diskette Write must be set to Enabled).
on The floppy disk drive is write-protected.
off Read, write and delete floppy disks is possible (default setting).
