Just opened a New Three truck shay with Tsunami sound etc. Do not have dcc unit yet.
Ran on dc linear power. When throttle in forward, the rear light is on and when reverse
the front light is on. When in forward and throttle depressed the engine ran fine but had three toots as in reverse. What is the problem.

Has anyone used the Airwire 9000 with the Spectrum Tsunami. Im new to DCC and need any help possible.
