[GreenKeys] I (don't) hear bells...

[Rokumon Cat]

Hi one more time this morning!
 
I was wondering (again) how to get the bells working in my ASR 28 and my Model-15. They both have bells, but I can get neither to go 'ding' even when sending "FIGS BELL".
 
Just curious, as I am considered a bit echm, 'dingy' by some. OK, sorry for the pun, but seriously, I would like to be able to hear the melodious tinkling of TTY bells as they are hammering away...
