Domonial : Can't Connect Tcu In Programming Mode

During programming the panel with the TCU, I think I entered a wrong adress or code. And now, I can't return in programming mode with the TCU because each time I press the panel tamper (3 seconds), the panel bip and the alarm sounds (but the panel is already disarmed !!). So the panel refuse to connect to the TCU. I notice, that if open a RF sensor, the tamper of the sensor triggered the alarme (I don't think that it was the same reaction before...I think only when the panel is armed but not when it was disarmed). .

So I don't know how to connect the TCU. I can't reset the panel to restore the originals parameters because I need to connect TCU too in programming mode !!.

Thank you in advance.

Sorry for my english speaking...
