Note: * CV 37: The short horn function can be changed to a grade crossing horn sequence by changing CV 37 to 0. If you would like to re-map the short horn function to another key using SoundTraxx' Flex-MapTM function mapping, CV 37 must also be set to 0 to prevent the short horn function from being activated with function key 3.
*CV 1.403: From the factory, Tsunami2 equipped Athearn Genesis models feature three types of functioning brakes for more prototypical operation. In order to use these brake rates to slow and stop your model, you must disable the automatic brake release. Set CV 1.403 to 0 before programming any brake rates in CV 117 (Independent Brake Rate) or CV 118 (Automatic Brake Rate) to allow control of the brakes with function key 11.
