    Troubleshooting way


    The main euipment cannot be power on to work

    Check if the power outlet is normal.

    Check if the power adapter is normal.


    When the main euipment is woring,but the output signal is weak

    Check if the input RF cable and connector are tight;

    Use your mobile phone to check if the outdoor antenna position has a strong signal.;


    The phone signal is full while the call quality is poor and the internet speed is low.

    Check if the input RF cable is damaged and the connector is tight;

    Adjust the position of the host and the outdoor antenna. It is recommended that the horizontal distance be greater than 10 meters, and it is better to have a wall in the middle to prevent the host from self-exciting.


    The host does have signal output, but the indoor coverage area is small.

    Adjust the position of the outdoor antenna to increase the received signal strength;

    Place the host in the center of the coverage area to cover a larger area;

    Replace the higher power host.


    After the device working for a period of time, the signal strength decreases and the coverage becomes smaller.

    Use your mobile phone to check if the outdoor antenna position signal is weak. Is there any cover?

    Whether the antenna installation direction changes and the antenna is damaged;

    Whether the outdoor antenna has its own RF cable is well or the connector is tight;
