DFM (Don't Forget Me) is a device designed to avoid losing of the transmitter with an acoustic and visible notification that alerts the operator whenever Scanreco radio transmitter is not in the truck cabin.
There are two parts in this system: the first one must be fixed into the transmitter, the other one (picture to the side) must be placed in cabin.
Through a special magnet placed within these parts, an attraction force allows the device to remain attached to the outside of transmitter and detect its presence.
You can install DFM device on both Maxi and Mini radio transmitter. Installation is really simple and will be illustrated in a separate document.
