Use the R9 Group Buttons Assembly to replace the 4-key button assembly which is used at each group of the Rocket R9. We recommend that if one of your groups’ buttons stops working, you should replace the whole assembly as one bad button might indicate the whole batch is on it’s way out. Please only purchase this to install if you feel technically skilled enough to do so, as we cannot provide any technical assistance over the phone.
