A touch member of a mobile communication terminal, the touch member comprising - a touch surface comprising sensor electrodes (21-23, 31-33) that are separated from each other on the touch surface, each of the sensor electrodes producing a sensor signal upon a user touch of the sensor electrode and each of the sensor electrodes having a certain determined sensor signal threshold that has to be reached in order to establish the corresponding sensor electrode, and - within the touch surface, a first area associated with at least two (21-22, 31-32) of the sensor electrodes and a second area associated with at least one (23, 33) of the sensor electrodes, - a controller, wherein the controller, upon a user touch of the touch member in an unlocked operation state, the unlocked operation state referring to a state wherein the touch member is ready to receive input, is arranged to - monitor periodically sensor signal levels received from each of the sensor electrodes to indicate a touch location, - calculate periodically the touch location with respect to the first area of the touch surface, - compare the sensor signal levels of each of the sensor electrodes in the second area of the touch surface to the signal level threshold of the corresponding sensor electrodes to produce compared signal level information, and - select an operation state of the touch member based on calculated touch location information and the compared signal level information, wherein the controller is configured to - select an activated operation state, if two adjacent sensor electrodes are established at the same time, the calculated touch location information indicates that the touch location is within the first area, and the sensor signal levels of the sensor electrodes in the second area do not reach the signal level threshold of the corresponding sensor electrode, the activated operation state referring to a state wherein a functionality associated with the touch member will be performed, and - select a locked operation state, if a sensor signal level of a sensor electrode in the second area reaches the signal level threshold of the corresponding sensor electrode, the locked operation state referring to a state wherein the touch member is not able to input any information. -
