Assigning Timing Chips is quick and easy in Zone4.
Zone4 Go timing chips are labeled with a rack letter followed by a chip number. For example, rack ‘A’ contains chips labeled ‘A1’, ‘A2’, ‘A3’ through to ‘A98’, ‘A99’, ‘A00’.

Simply type the letter of the racks being used into the Chip Racks Field, and then Click “Assign Timing Chips”. Zone4 will take care of the rest and attempt to assign the chips so that the number matches up with the racer number where possible.
