I have also found that the individual headsets need to "tap in". If the hub does it, it messes things up and can be difficult to get everyone back (this is using the three sets).
Mert, I think your issue with the 4 systems not working flawlessly together is that those 4 sets don't stay together. If you have two and they are paired, and then you add two more from other crews the other crews sets will remember who they paired with last. So if your contract climber was working with another crew 2 days ago, then his system will need to be re-programed into yours. That means all 4 helmets that your using that day will need to go through Nicks process.
I have had the helmets for 3 years now and always had a problem with them. We run a 4 man crew so it was always a HUGE hassle to get everyone connected. I took the time one snowy day and did Nicks process, and it has worked flawless for us. Now, the chipper operator can chime in and out without interrupting the other users.
I would suggest you get just two more batteries. Label them, and then pair them when you haves your 4 man crew. Once those members who are not with you all the time leave, you can take your batteries back, store them in a safe place until you use those guys, or any guys who have the senas again. Just replace their batteries with the ones you have already programed to your crew....I hope this all makes sense.
