See How do I set up my Fitbit device?
We can't give any advice other than that unless you say something about what you have tried and where your difficulty is.
And it would be helpful to know what device is being used to setup the Zip.
Best AnswerZip is not listed as a choice on the "set up device" screen. I am guessing that fitbit no longer supports this, which is unfortunate. I hate watches. I really wish fitbit would bring back One and Zip.

Zip is listed for me as a set-up option on Android phone.
Another non-wrist option is the Inspire (non-HR), which comes with a clip, sold separately.
