    Hello

    This TNC worked well but suddenly its battery wire interrupted my TNC keys doesn't work at all and it hasn't any reaction , its monitor is same as attached picture.
    I think its program erased but whats is the solution.

    Looks like you lost the parameters. The default language is German. Install new batteries and then put your parameters back in the machine and you should be good to go.
