  • Page 3: Getting Started

    SSEMBLING THE Getting Started Follow the steps below to assemble your station. At various stages of this assembly, you will be advised to test the system to ensure proper functioning. 1. Detach and remove the extension tube from the support tube by cutting the two black cable ties.
  • Page 4 4. Prepare the rain collector for use. Detach the black rain collector cone from its base by rotating the cone counter-clockwise until its latches line up with the latch openings in the base and then lift the cone off. (The cone fits tightly and may require extra pres- sure to remove it the first time.) Carefully cut and remove the black cable tie which holds the bucket in place during shipping.

Power Adapter Power Adapter Note: As illustrated above, if you are using the WeatherLink in addition to the SensorLink Receiver, you will need to position the receiver outside the mounting base.

  • Page 6: Lithium Battery

    If you have a non-solar-powered system, decide whether you want to install the power adapter OR the lithium battery (the two will NOT work in tan- dem or as backup). Davis recommends the battery to ensure power during storms. If used as the primary power source, one fresh lithium battery should provide about six months of service.
  • Page 7 For roof mounting, and for ease of installation in other locations, we recommend using the optional Mounting Tripod (contact Davis for more information). As you position your console, be aware of possible interference from cordless phones and other items.
  • Page 8 ESTING ROPOSED Test your proposed console and sensor locations to ensure successful data transmission. 1. Temporarily place the sensor array where you plan to mount it. 2. Apply power to the sensor array (see step 7 on page 6). 3. Set dip switch #4 on the transmitter to the TEST position, as shown below. This puts the transmitter in Test Mode —the Indicator LED will flash to indi- cate that the sensor unit is transmitting.

    ID code. Use the default setting unless you have another Davis wireless weather station operating nearby which you want to work separately from the new system. The dip switch settings for the eight possible codes are shown below.
  • Page 10 Silent Operating Mode Dip switch #4 on the receiver allows you to set the console to either emit audi- ble warnings or stay silent. In Silent Mode, the console does not beep to indicate problems such as low battery or poor reception. The factory sets Silent Mode off as the default so that the console will warn you when problems occur.

Please refer to the tripod manual for tripod installation instructions. Note: If mounting on a roof, tower, or other elevated structure without the tripod, be sure to consider the effects of wind loading and vibration and design the installation accordingly.
  • Page 12 Important: Mount Station Pointing South The station’s wind direction is calibrated as if the horizontal part of the ane- mometer arm were pointing south. To take advantage of the station’s preset wind direction, be sure to mount your station with the anemometer arm pointing south.

If two beeps or more are heard in a 2.5-second interval, then another Davis wireless system may be operating nearby on the same ID (or a cordless phone may be operating within 10 feet of the receiver). Try changing to a different ID code on both the console and the sensor array (or try moving the phone).
