Hi Andrew, yep sorry you are right, I only quickly read the thread and it was the pressing of the green but that made me think you were talking about the Viper 4Kv20, but yes you are correct no reset on button on the Viper 4Kv20.
It's been a while since I've fired up the Viper 4K here to be honest, I will do so next week when back in the office and remind myself how it works and follow up here.
