-   Each racer needs a bib number assigned to them
-   On the Zone4 phone, go to the Keypad tab

-   On the Keypad, enter only 1 bib number (it can be any bib number that is within that specific start group)
-   Example: If the Open Women category has bib 1 – 54, the starter can enter number 2 on the keypad and when they press enter, it will give a start time to the entire Open Women category.
-   Once it is keyed in. Once the starter says go, press enter on the phone keypad.
-   That will give a start time to the full group
-   Repeat these steps for each start group.
