[RTTY] AGC: on or off?

[Peter Laws]

I keep seeing mention of AGC.  That's the one control on my IC-746Pro
I admit to not knowing how to set.  I've read the Handbook section on
AGC and the manual entry and, of course, fiddled with it ...  so? 
Where do I set it for RTTY?  SSB?  It's got a fast/med/slow setting
for each mode and each preset is adjustable, including to "off".
