    2 Unpacking Open your weather station box and inspect that the contents are intact (nothing broken) and complete (nothing missing). Inside you should find the following: Item Description Display Console Outdoor Sensor Body with built-in: Thermo-hygrometer / Rain Gauge / Wind Speed Sensor/ Wind Direction Sensor, Light and UV sensor, Solar panel Wind speed cups (to be attached to outdoor sensor body) Wind vane (to be attached to outdoor sensor body)
  • Page 6 Note: Batteries for the outdoor sensor package are not included. You will need 2 AA size batteries, alkaline or Lithium batteries (Lithium recommended for colder climates). Note: The console operates using an AC adapter. The included adapter is a switching-type adapter and can generate a small amount of electrical interference with the RF reception in the console, when placed too close to the console.

    4 Set up Guide To complete assembly you will need a Philips screwdriver (size PH0) and a wrench (size M5; included in package). Note: We suggest you assemble all components of the weather station, including console in one location so you can easily test functionality. After testing, place the outdoor sensor package in the desired location.

If issues show up after outdoor mounting they are almost certainly related to distance, obstacles etc. 4.1.5.2 Mounting Your package includes two U-Bolts, 4 nuts, and a metal mounting plate for the U-Bolts, in addition to a small section of metal pipe.
  • Page 16 Finally, place the sensor package on top of the prepared mounting pipe. The U-Bolts should be loose enough to allow this but loosen the nuts as necessary. Once placed, hand tightens all four nuts, taking care to do so evenly. Do not use a wrench yet! Now you will need to align the whole package in the proper direction by rotating it on top of the mounting pipe as needed.

    Make sure you check, and correct if necessary, the westerly orientation as the final installation step, and now tighten the bolts with a wrench. Do not over tighten, but make sure strong wind and/or rain cannot move the sensor package. Note: If you tested the full assembly indoors and then came back here for instructions and mounted to sensor package outdoor you may want to make some further adjustments on the console.
