1.4 Handling Precautions
Like most development boards, the DB1065 is designed for use in office and laboratory
environments. The following practices will help ensure its proper operation.
1.4.1 Static Protection
The DB1065 uses low power CMOS circuits which can be partially or completely damaged by
electrostatic discharge. Partially damaged circuits can function erroneously and provide
misleading test results which can be time consuming (and extremely frustrating) to resolve.
Please observe common industrial static handling precautions when un-packing or handling the
printed circuit board.
1.4.2 Cleanliness
Because some DB1065 circuits are very high impedance, it is important to maintain their
cleanliness. All flux and other contaminants should be thoroughly removed after making any
additions or modifications to the circuit board.
1.5 Unpacking
After reviewing the instructions in section 1.4, Handling Precautions, check to make sure that
each of the following items are provided in the quantities indicated:
