How to Program a Schwinn SC-8

The Schwinn SC-8 is a cycle computer that displays information about your trip. It is mounted on the handlebars of your bike for easy viewing. It displays information such as current speed, average speed, maximum speed, the time of day, the amount of time you've been riding, the trip distance and an odometer. To set up the Schwinn SC-8, you must first initiate the computer and then calibrate the device.

Mark this spot and measure with a measuring tape in millimeters. This is the circumference of the wheel.
