Important notices for handling the system board:

When handling the system board, bear the following in mind.

•The system board has an accelerometer, which can be broken if several thousands of G-forces are applied.

Note: Dropping a system board from a height of as little as 6 inches so that it falls flat on a hard bench can subject the accelerometer to as much as 6,000 G's of shock.
