Inspection
When the equipment is received, all items should be care-
fully checked against the bill of lading to insure a complete
shipment. The shipping receipt should not be signed until all
items have been accounted for. All units should be carefully
inspected for damage upon arrival. All shipping damage
should be reported to the carrier and a claim filed. The unit
serial plate should be checked before unloading the unit to be
sure that it agrees with the power supply available.
