The present invention relates to a radio remote control system of a machine that comprises at least one machine drive for a moveable machine part, which machine drive can be controlled by the radio remote control system, comprising a hand-held unit (10) comprising a control unit, a transmitter and at least one motion sensor, wherein the control unit is configured to communicate control commands issued by a user to a transmitter, and to cause the transmitter to transmit the control commands to the machine, in particular to an associated receiver, and wherein movements of the hand-held unit (10) in space about at least one tilt axis or pitch axis (KA, DA) can be detected by the motion sensor in such a way that in a motion control mode, the detected movements can be converted by the control unit into control commands, which can be communicated to the machine, wherein the motion control mode can be activated by a user input at the hand-held unit (10). It is proposed according to the invention that the control unit is also configured such that on activating the motion control mode, the current attitude (I) of the hand-held unit (10) in space is detected as the current reference attitude (I), so that movements relative to this current reference attitude (I) can be detected by the motion sensor, and can be communicated by the control unit as control commands to the machine. The invention also relates to an operating method for a radio remote control system according to the invention. |
