Case 0: A bell is called to you (five or more bells) (you are unaffected)

The bell two places behind will change places with the bell following you. You will continue in the same place, following or leading off the same bell, and it is following or leading off the same bell. You were named in the call but you don't have to do anything and the two bells in front of you stay the same. This case only occurs for five or more bells, when you are at least two places down from the back.

Case 0a: A bell is called to you (four bells only)

The bell two places behind will change places with the bell following you. You will continue in the same place, following or leading off the same bell, but it will be following or leading off another bell (the one that had been following you). You were named in the call but you don't have to do anything except figure out which bell will be two places ahead. This case only occurs for four bells, when you are in leads or 2nds.

Case 2: A bell is called to the bell you are following

Case 4: The bell two places ahead is called away to some other bell

The bell two places ahead will change places with the bell it is following. You will continue in the same place, following or leading off the same bell, but will be two places back from a different bell. This case cannot occur if you are in 3rds.

This case only occurs with five or more bells. In the case of four bells, for the bell two places ahead to be called away, it has to be called to you; that is Case 0a.

Case 5: All other calls (you are unaffected)

You are unaffected, and the two bells in front of you are also unaffected. Relax and keep ringing.

If you are in 6ths or later

The call: G to E EGF…CDB
If you are in 5ths or later

The call: F to lead FE…CDB
If you are in nths (2nds or later),
out of at least n+6 bells
Before the call: …ABDEFGH…
The call: F to D …ABDFEGH…
If you are in leads,
out of at least six bells
Before the call: BDEFGH…
The call: F to D BDFEGH…

None of these are possible if you are ringing on four or fewer bells (why not?) in which case you have to think and/or move at every call; and only one of them is possible (which one?) if you are ringing on five bells.
