Inspecting and Unpacking the Shipment
The CrossCheck CDPD may be shipped in one or more cartons, 
depending on the number of units and the options ordered with the 
shipment. Before opening the shipping containers, inspect the cartons 
for punctures or damage and immediately report any damage to the 
shipping carrier. Then open the shipping cartons individually and 
check their contents against the packing slip.
