Please check whether or not the handheld device is connected to the WFR-01 network, then confirm whether or not the connection between WFR-01 and the karaoke machine is correct. If IR control is used check whether or not the playlist USB is inserted into the WFR-01 and the playlist is correct. If the above situations have been excluded but you still cannot be synchronized, then something is wrong. You can contact our service unit to check the problem.
