Locate the desired position and then rotate the CAM1 to one side by loosening the post clamp. Always make sure the post stop is secure first before loosening the post clamp. Apply a double sided adhesive pad either to the skin, or to the underside of the plastic plate on the end of the restraint arm.
Lower the restraint arm so that the plastic plate makes contact with the finger. Some pressure may be needed to get the adhesive to stick to the skin surface, but once it has stuck, avoid applying too much downward pressure when the restraint arm is clamped.
