How far away were you from the panel when you learned the bell. Need to learn everything on close to receiver, then go and put everything up in its location starting with closest to the panel first. The bell is no different to anything else with regards learning so not sure why you had the issue.
Yep no problem I will get that sorted for you, give me a shout tomorrow once you have spoken to the customer so I can arrange to get this shipped. Once you have the other gear out if you can pack it I will get it picked up.
