An appellant or representative may record the hearing with his or her own equipment. Filming, videotaping or televising the hearing may only be authorized when prior written consent is obtained from all appellants and contesting claimants, if any, and made a matter of record. In no event will such additional equipment be used if it interferes with the conduct of the hearing or the official recording apparatus. In all such situations, advance arrangements must be made with the Board of Veterans' Appeals, P.O. Box 27063, Washington, DC 20038.
