Safety Instructions
Before You Begin
Before handling your MBATX-945G-VGA board, read the instructions and safety
guidelines on the following pages to prevent damage to the product and to ensure your
own personal safety. Refer to the “Advisories” section in the Preface for advisory
conventions used in this user’s guide, including the distinction between Warnings,
Cautions, Important Notes, and Notes.
Always use caution when handling or operating a computer. Only qualified,
experienced, authorized electronics service personnel should access the interior
of a computer. The power supplies produce high voltages and energy hazards,
which can cause bodily harm.
If you have any problems or questions about the unit, please contact Kontron
Post-Sales Technical Support.
WARNING
High voltages are present inside a computer chassis when the
unit’s power cord is plugged into an electrical outlet. Turn off
system power, turn off the power supply, and then disconnect
the power cord from its source before removing the chassis
cover. Turning off the system power switch does not remove
power to components.

page 8 MBATX-945G-VGA User’s Guide
When Working Inside a Computer
Before taking covers off a computer, perform the following steps:
1) Turn off the computer and any peripherals.
2) Disconnect the computer and peripherals from their power sources or
subsystems to prevent electric shock or system board damage. This does not
apply when hot swapping parts.
3) Follow the guidelines provided in “Preventing Electrostatic Discharge” on the
following page.
4) Disconnect any telephone or telecommunications lines from the computer.
In addition, take note of these safety guidelines when appropriate:
To help avoid possible damage to system boards, wait five seconds after turning
off the computer before removing a component, removing a system board, or
disconnecting a peripheral device from the computer.
When you disconnect a cable, pull on its connector or on its strain-relief loop, not
on the cable itself. Some cables have a connector with locking tabs. If you are
disconnecting this type of cable, press in on the locking tabs before
disconnecting the cable. As you pull connectors apart, keep them evenly aligned
to avoid bending any connector pins. Also, before connecting a cable, make sure
both connectors are correctly oriented and aligned
CAUTION
Do not attempt to service the system yourself. Follow installation
and troubleshooting instructions closely.

MBATX-945G-VGA User’s Guide page 9
Preventing Electrostatic Discharge
Static electricity can harm system boards. Perform service at an ESD workstation and
follow proper ESD procedure to reduce the risk of damage to components. Kontron
strongly encourages you to follow proper ESD procedure, which can include wrist straps
and smocks, when servicing equipment.
You can also take the following steps to prevent damage from electrostatic discharge
(ESD):
When unpacking a static-sensitive component from its shipping carton, do not
remove the component’s antistatic packing material until you are ready to install
the component in a computer. Just before unwrapping the antistatic packaging,
be sure you are at an ESD workstation or grounded. This will discharge any
static electricity that may have built up in your body.
When transporting a sensitive component, first place it in an antistatic container
or packaging.
Handle all sensitive components at an ESD workstation. If possible, use antistatic
floor pads and workbench pads.
Handle components and boards with care. Don’t touch the components or
contacts on a board. Hold a board by its edges or by its metal mounting bracket.
Do not handle or store system boards near strong electrostatic, electromagnetic,
magnetic, or radioactive fields.

Regulatory Compliance Statements
This section provides the FCC compliance statement for Class B devices and Safety
Standards.
FCC Compliance Statement for Class B Devices
The product(s) described in this user’s guide has been tested and found to comply with
the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits
are designed to provide reasonable protection against harmful interference when the
equipment is operated in a residential environment. This equipment generates, uses,
and can radiate radio frequency energy and, if not installed and used in accordance with
the user’s guide, may cause harmful interference to radio communications. However,
there is no guarantee that interference will not occur in a particular installation. If this

be determined by turning the equipment off and on, the user is encouraged to try to
correct the interference by one or more of the following measures:
•Reorient or relocate the receiving antenna.
•Increase the separation between the equipment and the receiver.
•Connect the equipment into an outlet on a circuit different from that to which the
receiver is connected.
•Consult the dealer or an experienced radio/TV technician for help.
You are cautioned that changes or modifications not expressly approved by Kontron
could void your authority to operate the equipment. This device complies with Part 15 of
the FCC Rules. Operation is subject to two conditions:
1) This device may not cause harmful interference.
2) This device must accept any interference received, including interference that
may cause undesired operation
Note: The assembler of a personal computer system may be required to test
the system and/or make necessary modifications if a system is found to cause
harmful interference or to be noncompliant with the appropriate standards for its
intended use.
