What is the law on the duty of looking after his legal rights and of calling the judge's attention to any infringement of his rights?

" ' " 'The law casts upon the party the duty of looking after his legal rights and of calling the judge's attention to any infringement of [his or her rights]. If any other rule were to obtain, the party would in most cases be careful to be silent as to his objections until it would be too late to obviate them, and the result would be that few judgments would stand the test of an appeal.' " ' [Citation.]" (Fn. omitted; [citations].)' [Citation.]" (Keener v. Jeld-Wen, Inc., supra, 46 Cal.4th at pp. 264-265, fn. omitted.)
