    3.3.1 Ventilation The FS22DI is an electronic equipment with active ventilation, meaning that it uses fans for thermal control of the device. Fine dust particles over time can reduce the life time of optical and electronic components leading to a general degradation of the equipment, so it is important to prevent dust from entering the device.
