How do I set up a user profile or switch between different user profiles?

To set up a user profile or access the next user profile when the computer is on, press and hold the reset button. You'll then see one of U1, U2, U3, U4 flashing on the screen. Select the user profile you want by turning the dial until you get to the profile you want and press the dial. Set the value for gender by turning the dial until the value you want is displayed, then press the dial again. Repeat the process for age, height and weight. After entering the weight you'll be taken to the home screen, ready to start using the machine.

The computer stores the values for each user profile. So when user 1 finishes their workout, user 2 will press and hold the reset button. They'll then be able to turn the dial to get to U2 and then press the dial to select it. All values will be stored from before so simply keep pressing the dial until you reach the home screen. All feedback will now be based on the user profile selected.
