Or you could refer to the tuning thread.

lol, Sorry I had to. Also you can tune it by yourself without a tuner as long as you have basic knowledge of the fretboard and a fretboard diagram (not neccesary if you have memorized the fretboard). Just tune the 5th string first using the first string as a guide, then go down the strings tuning each one using the previous one as a guide. Then guess and check for the 6th string until it matches the 5th string. That was really vague because I don't know the tuning pattern for Db so I can't tell you what frets to use as guides.
