What are the audio-visual link requirements for a remote dispensing location?

Every remote dispensing location (RDL) where a pharmacist is not physically present must be equipped with a live, two-way audio-visual link that permits dialogue and communication between the patient and a pharmacist who is physically present in the accredited pharmacy. In the event of a disruption in this link, all dispensing at the RDL must cease immediately and cannot resume until the link is restored.
