5 CFR 1201.52: Public hearings.

(a) Closing the hearing. Hearings are generally open to the public; however, the judge may order a hearing or any part of a hearing closed when doing so would be in the best interests of a party, a witness, the public, or any other person affected by the proceeding. Any order closing the hearing will set out the reasons for the judge's decision. Any objections to the order will be made a part of the record.

(b) Electronic devices. Absent express approval from the judge, no two-way communications devices may be operated and/or powered on in the hearing room; all cell phones, text devices, and all other two-way communications devices shall be powered off in the hearing room. Further, no cameras, recording devices, and/or transmitting devices may be operated, operational, and/or powered on in the hearing room without the consent of the judge.
