They are parameters associated with the Automatic Gain Control. The idea of AGC is to try and maintain a reasonably constant listening level regardless of changes in propagation or local noise. The characteristics can be changed to suit personal preferences and the type of signal you are monitoring.
Here's a link that covers AGC in detail (more than you are ever likely to need).
GE Martin thank you for the AGC pdf, it is always interesting to re-learn almost forgotten characteristics plus the digital part. In an ANALOG radio the AGC is that never-used switch, or by me just in few cases put on FAST , never on OFF and always on SLOW because it sounds much more confortable. In a digital radio all functions are done in software and that is much uncomprensible to me. (plus some grammar mistakes in english...) 73 Phil IC8POF
