Please forgive me in advance for me asking a basic question but I am struggling! I have a pair of 18s, a Core and now a Transmitter 1. I am really struggling to get set up so all wireless. I know it should be straightforward but I am lost. I can get one 18 connected to Transmitter 1, but not the other! I am uncertain as to how properly link the Core (I am using a PL from Core to PL4 on Transmitter but is this wrong??) and then I am lost to the settings I should put into my app for the Core. Again, am terribly sorry for asking this but is there any simple way of helping explain what I need to do?? Many thanks for any tolerant soul who may help.
