## Setup & Placement

<Steps>
  <Step title="Charge the battery">
    Before first use, fully charge your AT2 using the included USB cable. Connect it to any USB power source (wall adapter, laptop, power bank). A full charge typically takes **2–3 hours**. The LED will change colour when charging is complete.
  </Step>

  <Step title="Activate your subscription">
    Before the AT2 can transmit location data, you need an active subscription. Visit [shieldgps.co/activate](https://shieldgps.co/activate) and complete the registration steps using the IMEI printed on the device packaging.
  </Step>

  <Step title="Power on the device">
    Press and hold the power button for **3 seconds** until the LED flashes. The AT2 will begin searching for GPS signal and connecting to the 4G network.
  </Step>

  <Step title="Choose your placement location">
    Use the strong built-in magnet to attach the AT2 to any metal surface on your vehicle or asset. Common hidden locations include underneath the vehicle chassis, inside a wheel arch, behind a metal panel, or inside the boot/trunk near a metal floor plate.
  </Step>

  <Step title="Attach the device">
    Press the AT2 firmly against the metal surface — the magnet will hold it securely. Give it a light tug to confirm it won't come loose during movement. For extra security on rough terrain, you can secure it further with cable ties or adhesive pads.
  </Step>

  <Step title="Verify tracking in the app">
    Open the ShieldGPS app and confirm the AT2 is showing a live location on the map. Updates arrive every 10 seconds when the device is in motion.
  </Step>
</Steps>
