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 device.

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 device.

Before disconnecting cables from the system board remember how the connectors are

plugged in. Some connectors may not be coded.

Incorrect replacement of the lithium battery may lead to a risk of explosion. It is therefore

essential to observe the instructions in the section „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.

Data 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.

Upgrading main memory

The system board is equipped with two 168 pin sockets with which the main memory can be

upgraded to a maximum of 256 Mbyte.

These slots are suitable for 16, 32, 64 and 128 Mbyte SDRAM memory modules of the DIMM

format.

Memory modules with different memory capacities can be combined.

DIMM = Dual Inline Memory Module

SDRAM = Synchronous Dynamic Random Access Memory

!Depending on the processor type SDRAM memory modules must be designed for a

clock frequency of 66 MHz or 100 MHz or higher (meets PC100 specification).

Upgrading main memory
