(a) As to disqualification of officer. Objection to taking a deposition because of disqualification of the officer before whom it is to be taken is waived unless made before the taking of the deposition begins or as soon thereafter as the disqualification becomes known or could be discovered with reasonable diligence.

(b) As to taking of deposition. (1) Objections to the competency of a witness or to the competency, relevancy, or materiality of testimony are not waived by failure to make them before or during the taking of the deposition, unless the ground of the objection is one which might have been obviated or removed if presented at that time.

(2) Errors and irregularities occurring at the oral examination in the manner of taking the deposition, in the form of the questions or answers in the oath or affirmation, or in the conduct of parties, and errors of any kind which might be obviated, removed, or cured if promptly presented, are waived unless reasonable objection thereto is made at the taking of the deposition.
