Turning the device on for the first time
Let's turn the device on--at the back, you will find the power button. Next to that are five LEDs that indicate whether the device is active and the state of the batteries. Each LED stands for 20% of the remaining power; so, assuming your device is fully charged, you will see five LEDs that are switched on. When you wear the device and press the power button, you will be greeted by a friendly "Hello", followed by either a "Scanning your environment" message or the start menu. The "Scanning your environment" message means that the device is looking at the environment. It will map all surfaces and will see if it recognizes them. If it does, it will load the known environment and use that, otherwise it will store a new one.
If this is the first time you have turned on the device, you have to personalize it. The steps necessary are simple, and the wizard will walk you through it, I will not go into that here. However, it is important to note that one step really should not be skipped--the network configuration. The device does not have a built-in GPS receiver and will rely on the network to identify the place it is in. It will store the meshes that make up the rooms and identify those with the network identifier. This way, it will know whether you are using it in your house or in your office, for instance. Next to that, applications, such as Cortana, need network connectivity to run, so the device can only really reliably be used in areas with a decent Wi-Fi reception.
One of the steps required is entering your Microsoft account. If you do not have one, I advise you to set one up before starting the device.
