Inspect the carton(s) for dents and/or damage, report the results to a superior or supervisor in charge

if damages are noted. Do not unpack the unit until authorized.

Unpack the ANCD unit while following the packing method illustration and list of materials, see Table

2-1. Do not damage the packing materials; they should be stored in the carton in case the ANCD will

be stored or shipped at a later date.

Once the ANCD is exposed, perform a visual inspection of the housing assembly. Inspect the housing

for cracks. Check the fill connector and CIK and it's socket for damage. Open the display cover, check

the Liquid Crystal Display (LCD) for cracks and the keyboard for damage. Report any discrepancies

noted to a supervisor.
