The 998  has the same thing.  It's pretty clunky and I don't use it 
myself.  It needs to be set in one of the menus.

I don't know if the 994 does it different, but in the 998, a single beep 
is for  swr between 1.0 and 1.5, 2 beeps for 1.5 up to 2.0, 3 beeps for 
2.0 up to 2.5, and 4 beeps from 2.5 through 3.0.   Don't remember what 
happens above 3.0, maybe smoke and flames.
