Simply place it on a suitable stand* or otherwise adjust it so that it sits in a position appropriate for your child’s height. Note: Connecting the FC35 to any of these models placed on a desk will place pressure on the FC35 cable, which may damage the cable. Accordingly, we ask that you refrain from using the FC35 with any of these models placed on a desk.
