(A) Notice of the place, if any, the time, and the purposes of any meeting of voting members or directors, as the case may be, whether required by law, the articles, the regulations, or (in the case of directors) the bylaws, may be waived in writing, either before or after the holding of such meeting, by any member, or by any director, which writing shall be filed with or entered upon the records of the meeting. A transmission by authorized communications equipment that contains a waiver is a writing for purposes of this division.
