How to add analog Channel to XIR-P8668 Radio without error?

Does anyone know what can be done for the XIRP8668 motorola portable radio program and fix the error of not being able to add an analog channel? Do I have to buy a special license or not?

When I read the device and add the analog channel While writing the radio, an error message appears stating that it is not allowed to add the analog channel

Thank you for your help friends
