			<li> Massage Pad - To simulate the vibrations in diffusion sequences, particularly in children's studies, we now have massage pad. The massage pad measures 12 inches by 12 inches. To use the massage pad correctly, place the pad on the simulator bed and position the pad to be right below the shoulder blades of the subject. There are two heat and two massage levels on the Slide Control Box. Setting the massage level on LO simulates the diffusion sequence quite well. It is not necessary to use any heat settings. When you are finished using the pad, turn the controller off and unplug the pad from the wall socket. For now the pad is stored on the window ledge by the simulator bed.
