Plug the Tactile Unit (8) into the socket (5). The Tactile Unit should work immediately with the red/green LED (7) indicating the current speed. To adjust the speed and the intensity of the vibration, use the speed control (1) and the vibration control (6). Please turn both controls slowly because there is a time delay in the microprocessor.
You can use the Tactile Unit in conjunction with the Audio Scan or independently.
The tactile device draws a lot more current than the acoustic stimulation. If the clicks are still loud and clear but the tactile device vibrating weakly then it is necessary to change the battery.
Please not that the Audio Scan Basic Unit is not part of the tactile Unit (for illustration purpose only) and needs to be purchased separately.
