When an administrative appeal is entered, the claimant and his or her representative, if any, will be promptly furnished a copy of the memorandum entitled ``Administrative Appeal,'' or an adequate summary thereof, outlining the question at issue. They will be allowed a period of 60 days to join in the appeal if they so desire. The claimant will also be advised of the effect of such action and of the preservation of normal appeal rights if he or she does not elect to join in the administrative appeal. (Authority: 38 U.S.C. 7106)
