Now that your Hyperpac is connected, you can turn your key to the "on" position and fire up the computer. A start-up screen with the Hypertech logo will show up for about 10 seconds before the computer begins to lead you through the setup process. The setup will only happen the first time you turn on the Hyperpac. After the initial setup, it will go straight to the main menu when you start the truck. You can change the settings if you ever get a different truck or make alterations to your current rig.
