I use TTS datamaster and had the same problem where it would kick on and off recording. There was a disable CCM handshake option and once I turned that off it worked like a champ. Mine's a 90, not sure if your 89 has a CCM though.
Mick is great to work with. He got mine running great with the Bosch III's and they were a lot quiter.
