An arrangement, system and method for reducing the effect of interference at radio frequencies in an electronic price label system. The arrangement includes an electronic price label system, which includes a base station equipped with at least a radio transmitter and a radio receiver as well as a set of electronic price labels that receive and reflect back radio signals from the base station. The electronic price label system is connected to an electronic article surveillance system which includes a detector device which is able to detect electronic article surveillance tags, and which electronic article surveillance system further includes an activation device for changing a state of the detector device between an activated-state and a deactivated state. The electronic price label system is configured to start transmitting transmissions from base stations and/or electronic labels only when the detector device of the electronic article surveillance system is in the deactivated state.
