For Conventional Radio:

    1. Why can’t I communicate with other group members?

      First, please verify that the channel frequency and the CTCSS you are using are 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.

    2. Why can I hear the voice from other groups?

      Please change your CTCSS for the channel. At the same time, you also need to the CTCSS for all the radios in your group. If you don’t like this, you may apply another channel frequency

    3. What is the battery life cycle?

      Please replace your old battery with a new one when the battery life cycle is over, so that you can get the best performance from your radios. For a Ni-MH battery, it is designed to a 500 standard recharge & discharge cycles; for a Li-ion, it is 1000 standard cycles.

    4. My radio can not scan channels? Why?

      This happens because when the radio is programmed, the channel is not included into the scan list. Or the whole channel scan function is not turned on for the radio. Please turn to a professional engineer to troubleshoot this problem.

    5. After the radio is programmed, there are noises from the radio like “dudududu”, Why?

      This happens because the radio is wrongly programmed. This noise is an indication that the channel frequency programmed is out of the frequency range supported by this radio. Please check your setting or turn to a professional engineer for help.

    6. After a period of time, my radio works well, but there’s no sound from my earpiece. What’s happened?

      The socket inside the radio has been damaged. Please return the radio to your Hytera authorized dealer for maintenance.

    7. Why is the radio communication range shorter than before and why has the sensitivity becomes poorer?

      Please check the antenna and make sure it is a good one. Also please check the antenna socket to ensure it is not damaged or loosened. If it is, please return the radio to your Hytera authorized dealer for maintenance.

    8. What is Radio to Radio Clone Method?

      When a lot of radios need to be programmed, the fast and secure way to do this is to do a radio-to-radio clone. Hytera radios can support wired clone and wireless clone, depending on the radio functionalities. Please contact your Hytera authorized dealer to get the detailed clone procedures for your radio.

    9. What kind of batteries do you offer and what’s the difference among them?

      There are 2 kinds of batteries we offer, i.e. Li-ion battery and Ni-MH battery.

    10. Why are the programming software updates so often, and why are some incompatible?

      To perfect the software, the updating is necessary, and the new ones have good compatibility. If you want the latest edition, we could supply it for you.

    11. How do I make my radio talk to others?

      Firstly, set the two radios at the same frequency, secondly, set the same CDCSS/CTCSS, and then they can talk each other.

    12. Is a long antenna better than a short antenna?

      No. Short antenna has a convenient-design, and are easy to carry. Long antenna cover wider communication range. So the choice all depends on the environment and personal favourite.

    13. How long is the communicate distance of TC-XX?

      The communicate distance would be disturbed by following factors:

      • Environment: If you use it around high buildings and large mansions, the communication range is smaller.
      • Weather: If you use the radio on a rainy day, the radio performance maybe poor.
      • Power: If the power of the radio is very low, you will have a poorer communication distance.
    14. How do I use the earphone correctly?

      • Do not pull the earphone cable tightly.
      • Do not stick in or pull out the earphone from the jack frequently.

    3. What is DMR Radio?

      Digital Mobile Radio; Based on a TDMA (Time division multiple frequency) Modulation protocol technology, operating in 12.5 kHz bandwidth channels, With 4 levels FSK (frequency shift keying) and advanced FEC (forward error correction) technology.

    4. How many time slots are available on a TDMA channel for data and voice communications?

      There are two time slots that can be used as audio or data channels (-e)

    5. Why is the battery life of a portable 40% longer?

      DMR technology is intermittent meaning 30milliseconds on 30 millisecond off.

    6. CPS; Under Channel (Digital/Analog); how does the Offset (MHz) works?

      Add +/- offset to receive frequency, RX Freq + (+/-Offset) = TX frequency

    7. What is the model for the Portable Programming cable?

      PC38

    8. What is the model for the repeater/mobile cable?

    28. How to judge the performance of different models of DMR Radios?

      Based on the different parameter: band range, Tx power, Rx sensitivity, and other data.

    29. The voice received on the radio is intermittent with rather big noises. Why?

      Usually, when the radios are at the edge of the coverage area or in some places where the radio signals are interrupted or blocked, this symptom will happen. Please kindly verify the above. If necessary, please return the radio to your Hytera authorized dealer for maintenance.

    30. Why can i hear the voices clearly from other groups but sometimes my voice is intermittent?

      Please check whether the MIC is blocked by something. If so, Please return the radio to your Hytera authorized dealer for maintenance.

    31. There is no display or something strange is displayed on my LCD? Why?

      This happens because of the poor connection between the LCD and PCB. The possible cause of this is that the radio was dropped and not used properly. Please return the radio to your Hytera authorized dealer for maintenance.

    32. I can not turn on the radio and even if it is turned on, it shuts off automatically. Why?

      Please check the battery contacts on the radio. If it is broken or twisted, please return the radio to your Hytera authorized dealer for maintenance.
