Notes: 1. These assemblies are ESD sensitive, ESD precautions shall be observed.

2. These assemblies must be clean and free from flux and all contaminants.

Failure to use clean flux is unacceptable.

3. These assemblies must comply with workmanship standards IPC-A-610 Class 2.

4. Reference designators marked with an asterisk ('**') cannot be substituted.

All other components can be substituted with equivalent MFG's components.
