7th Cir. R. 56

(a) Opportunity to State Objections and their Rationale. Whenever a rule of court requires concrete proposals or objections and reasons in order to preserve a claim for appeal (e.g., Fed. R. Civ. P. 51, Fed. R. Crim. P. 30, Fed R. Evid. 103(a)), the judge must ensure that parties have an adequate opportunity to put their proposals, objections, and reasons on the record. When the judge entertains proposals or objections off the record (for example, a sidebar conference or a jury instruction conference in chambers), as soon as practicable the judge must offer an opportunity to summarize on the record the proposal or objection discussed, and the reasons for the proposal or objection. The judge then must state the ruling made.

(b) Waiver. Parties offered an opportunity to make a record under part (a) of this rule must use it in order to preserve a position for appeal. No proposal, objection, or reason may be urged as a ground of appeal unless placed on the record. A lawyer who believes that he or she has not been given an adequate opportunity to make a record under this rule must so state on the record. This rule does not alter any obligation imposed by any other rule to make concrete proposals or to state objections and reasons in order to preserve a claim for appeal.
