Preventing electrostatic discharge 
To prevent damaging the system, be aware of the precautions you need to follow when setting up the 
system or handling parts. A discharge of static electricity from a finger or other conductor may damage 
system boards or other static-sensitive devices. This type of damage may reduce the life expectancy of the 
device. 
To prevent electrostatic damage: 
 
Avoid hand contact by transporting and storing products in static-safe containers. 
 
Keep electrostatic-sensitive parts in their containers until they arrive at static-free workstations. 
 
Place parts on a grounded surface before removing them from their containers. 
 
Avoid touching pins, leads, or circuitry. 
 
Always be properly grounded when touching a static-sensitive component or assembly.
