Important notes
Store this technical manual close to the device. If you pass on the device to third
parties, you should also pass on the Operating Manual.
!Be sure to read this page carefully and note the information before you
open the PC.
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 with regard to "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 cable for peripherals must be adequately insulated to avoid
interference.
!Modules can become very hot during operation. Make sure you do not
touch modules when adding components 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.

Possible screen resolution
Depending on the operating system used the screen resolutions in the following
table refer to the screen controller on the system board. If you are using an
external screen controller, you will find details of supported screen resolutions in
the Operating Manual or Technical Manual supplied with the controller.
To select the appropriate setting for your monitor, please use the

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).
