We know that almost all the DMR radios support firmware upgrade. Sometimes the new firmware improves lots of functions or adds some new functions. After upgrading the firmware, you may need to initialize your radio to make sure all the data is compatible. Or sometime we accidentally messed up the radio data, and want to restore factofy settings.
First we need that initialize the radio and restore radio factory settings are same.
