Maryland Commercial Law Section 2-606

      (1)      Acceptance of goods occurs when the buyer

            (a)      After a reasonable opportunity to inspect the goods signifies to the seller that the goods are conforming or that he will take or retain them in spite of their nonconformity; or

            (b)      Fails to make an effective rejection (subsection (1) of § 2-602), but such acceptance does not occur until the buyer has had a reasonable opportunity to inspect them; or

            (c)      Does any act inconsistent with the seller's ownership; but if such act is wrongful as against the seller it is an acceptance only if ratified by him.

      (2)      Acceptance of a part of any commercial unit is acceptance of that entire unit.
