Yeah... well.... I am sort of frustrated by this product myself, so I am not sure I can be of much help but I am willing to try anyway hoping it may help somewhat: In the manual a special chapter is dedicated to pairing one G4 with 2 other G4 units. In my (Dutch) manual this is chapter 9.10b First: you need to understand the setup. There are 3 drivers, all using G4's: riders A, B and C. In the example of the manual, rider B is "the middleman". Rider B is the only driver linked to both riders A and C, which means he uses one channel for rider A and one channel for rider B. In this setup, there is no channel left for rider B to use for a mobile phone (since bluetooth only has 2 channels), so he can not use one. Rider A and C however CAN use a mobile phone besides their connection to B. So this is the setup. In your own situation, create an equal setup. 1) Power up the G4's of riders B and C by clicking the mobile phone button (middle on top) until the blue light flashes three times. Both G4's are now ON. 2) No press on BOTH B and C G4 the Channel B button until the blue lights start to blink faster which should mean they are both ready for pairing up. 3) Now switch on the G4 of rider A (which is one of the G4's of the power set) and wait until he connects to his factory mate of the powerset (paired in the factory). So just put it ON and wait for it to connect to his pal. His pal is G4 rider B. Should this not happen, then push the Channel A button and force the connection between A and B. You now should have a 3 rider setup working. So you need to pay attention to the setup you have chosen. Who is rider A and B and who is rider C does matter since you have a powerset involved who are factory paired. I advise you to match your situation to the situation as described above, which should work. Let us know if it worked out.
