How can i tune a guitar with a fzone fmt-60?

well i can tell you a simple way to tune a guitar if you can reconize tones...starting at the biggest string put your finger on the 5th fret then play that string and the string below it change the tuning of the a string until they sound the same do this for all the srtings but one the one that will be different is when tuning the b string...you will use the 4th fret of the to tune that one
