The battery life is over, replace new one Couldnt communicate with other group members First, please verify that the channel frequency and the CTCSS you are using the same as those of your group members. If the channel frequency and the CTCSS are the same, please verify that your group members are within the radio coverage. Hear the voice from other groups  Please change your CTCSS for the channel. At the same time, you also need the CTCSS for all the radios in your group. If you dont like it, you may apply another channel frequency. Why can I hear the voices clearly from other group, sometimes, my voice is intermittent Please check whether the MIC is blocked by something. If so, please return the radio to your authorized dealer for maintenance. Sometimes, your frequency is same as the frequency of other groups.
