This summary is not the rule. The rule text controls.
If you disagree with something the judge decides during your case, you just need to say so and explain why. You don't have to use any special legal words or formal language to "except" to the ruling. In the past, courts required people to formally state an "exception" to preserve their right to challenge a decision later, but that's no longer required.
This also protects you if you didn't get a chance to object at the time. If the judge makes a ruling and you had no opportunity to speak up about it right then, you won't be penalized later for not objecting. Your case won't be hurt just because you missed a chance to object that never really existed in the first place.
In short, this rule makes things simpler. All you need to do is clearly tell the court what you disagree with and why, when you have the chance to do so.
