To operate, attach Audio Alert to a bed, chair, etc. with its integral elastic strap and affix the clip on the end of the cord to any part of the patient's clothing. If the patient decides to leave the immediate area, a magnet at the end of the cord is pulled away from the unit to emit a piercing alarm. A nurse is alerted to take appropriate action. Once the patient is secure, the magnet is placed back on the unit and the alarm ceases.
