Haris systems are a big PITA, and Haris wants it that way so you have to go to them for everything. First and foremost make sure you have a BN model, AN models no matter what you do will not work on Haris systems. Then I would check for the radio seeing the control channels, that's the issue I am having, as I get out of range display even when I am looking at the tower that this system is transmitting from. I have heard that Haris uses an non standard at least compared to Mot for the channel ID, with base frequency and step, bandwidth and offset, so make sure they match your working Haris radio exactly. Next make sure your radio is up to the last firmware version (20.05.07) that supposedly addresses the WACN issue. I have yet to see one work, and then if you are an admin try transmitting on the system and look up in the logs that the radio is being seen.
Beyond that give the radio back to Mot and let them fiqure it out.
