Important notices for handling the system board
When handling the system board, read the following:
• The system board has an accelerometer, which can be broken when several thousands of G-forces
are applied.
Note: Dropping a system board from a height of as little as 15 cm (6 inches) so that it falls flat on a hard
bench can subject the accelerometer to as much as 6000 G's of shock.
• Be careful not to drop the system board on a bench top that has a hard surface, such as metal, wood, or
composite.
• Avoid rough handling of any kind.
• At every point in the process, be sure not to drop or stack the system board.
