Hi you do not say which radio you use ? If nothing happens it's probaly not the LAN settings which is wrong. it's cables, radio mode or baud rate. If the RRC understand that you want to connect and the network/connection settings are wrong the you will get an error tone in the speaker. Don't forget to look at the status pages also. The most common error when setting up on LAN is that the user have forgot to change the default SIP contact to the current IP number of the radio RRC.
