(3) If a bank sends or makes available a statement of account or items pursuant toSubsection (1), the customer must exercise reasonable promptness in examining the statement orthe items to determine whether any payment was not authorized because of an alteration of anitem or because a purported signature by or on behalf of the customer was not authorized.
