I have a KSW10 connected to my Yamaha RX-V663. Sometimes when I turn the system on I only see a red light on the KSW10 which I think indicates it's on, but not producing bass. I then turn the system off and back on to get the green light on the KSW10 and then I hear the bass. What would cause this condition? All connections are tight. The KSW didn't really have any info with it to explain how it works and my knowledge level is you turn it on and it's supposed to work. If it makes any difference, I control all my components with a Harmony 890.
