I should clarify that technically you wouldn't have to do anything to force this system to TIIIStd. DSD+ should already be able to determine that it's a Hytera TIIIStd system even if you have nothing in your files, as shown below. Of course if you do want to label everything, you'd need to setup your files, and that's where making sure everything is TIIIStd as documented above comes into play.
