You mean the calibration for the paddle wheel speed, or water temp, or speed of sound thru water (salt and fresh water are diffrent)? Normally you don't change them unless you know one of the readings needs calibration/adjustment.

i mean the speed of sound thru water , it makes the read of the bottom more faster?

Normally it is never changed unless you are fishing in Fresh water versus Salt water.
