        • 14. Make sure the fan blades are rotating by directing the connected SIM cover to sunlight or by shining a bright incandescent light on the solar panel. You should hear a slight whir if the fan is running.
        • Guidelines for Securing Cables
      • Securing Cables
    • Note: Do not use metal staples or a staple gun to secure cables. Metal staples—especially when installed with a staple gun—have a tendency to cut the cables.
      • Take the Console Out of Setup Mode
        • 1. At your Vantage Pro2 console, press and hold DONE for three seconds to take the console out of Setup Mode.
        • 2. Check the console for erroneous rain data and clear if necessary.
        • 3. Congratulations! You have completed the upgrade and can now enjoy your daytime fan-aspirated radiation shield.
  • Maintenance
    • Annual Maintenance
      • 1. Remove your fan-aspirated ISS and place on a stable work surface.

      • 3. Disassemble the radiation shield.
      • 4. Remove any debris lodged inside the unit.
      • 5. Clean the surfaces of the radiation shield with a damp cloth.
      • 6. Assemble the radiation shield.
      • 7. Re-install the ISS in its previous location.
