(2) Upon commencing an investigation, the protective investigator shall inform all of the vulnerable adults and alleged perpetrators named in the report of the following:
(a) The names of the investigators and identifying credentials from the department.
(b) The purpose of the investigation.
(c) That the victim, the victim's guardian, the victim's caregiver, and the alleged perpetrator, and legal counsel for any of those persons, have a right to a copy of the report at the conclusion of the investigation.
(d) The name and telephone number of the protective investigator's supervisor available to answer questions.
(e) That each person has the right to obtain his or her own attorney.
Any person being interviewed by a protective investigator may be represented by an attorney, at the person's own expense, or may choose to have another person present. The other person present may not be an alleged perpetrator in any report currently under investigation. Before participating in such interview, the other person present shall execute an agreement to comply with the confidentiality requirements of ss. 415.101-415.113. The absence of an attorney or other person does not prevent the department from proceeding with other aspects of the investigation, including interviews with other persons. In an investigative interview with a vulnerable adult, the protective investigator may conduct the interview with no other person present.
