Removal steps of the P sensor 2 2 2 2 3 1 1100 System board 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 0.15 m (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. • If you put a system board down, be sure to put it only on a padded surface such as an ESD mat or a corrugated conductive material.
