The Act Commentary on Sections Section 7:  Warning to jury
42.This section requires the judge to warn the jury in Crown Court trials, in whatever way the judge considers appropriate, to ensure that the fact that the order was made does not prejudice the defendant. The provision is based on section 32 of the Youth Justice and Criminal Evidence Act 1999 which makes similar provision for jury warnings where a special measures direction has been made to assist a vulnerable or intimidated witness.
