This summary is not the rule. The rule text controls.
Here's what this rule means in practice.
After the judge tells the jury the legal rules they need to follow, both sides get a chance to speak up if they disagree with what was said. This happens away from the jury, so the jury doesn't hear the disagreement. A party can object because they think the judge got an instruction wrong, or because the judge left out something they had asked to be included.
The important part is what happens if a party doesn't object at this point. Normally in court, if you don't object right away, you lose the right to complain about it later. This rule works differently. Even if a party stays quiet and doesn't object after the instructions are read, they can still raise that same issue later when asking for a new trial. In other words, missing the chance to object at this stage doesn't automatically end their ability to challenge the instructions afterward.
This gives parties some protection. It means a mistake in the jury instructions can still be fixed later, even if nobody caught it or spoke up at the exact moment the judge read the instructions to the jury.
