  • Page 30 OUTDOOR TRANSMITTER 915 MHz RECEPTION CHECK The outdoor temperature, humidity, wind data are transmitted from thermo-hygro transmitter every 4.5 seconds; the rainfall data are transmitted from the rain sensor (optional) every 6.25 seconds. The receiver will be synchronized to the thermo-hygro transmitter and rain sensor (optional) then.

  • Page 31: Positioning

    Signals from the sensors can be received by the base station at points of mounting La Crosse Technology Sensor Extension Cable You can purchase a La Crosse Technology Extension Cable if you require additional length to properly mount your sensor. The extension cable is 32 feet in length and comes with the appropriate connecter attached.
  • Page 32 An ideal mounting place for the thermo-hygro sensor would be the outer wall beneath the extension of a roof, as this will protect the sensor from direct sunlight and other extreme weather conditions. Be sure to mount vertically. To wall mount, use the 2 screws to affix the wall bracket to the desired wall, plug in the thermo-hygro sensor to the bracket and secure both parts by the use of the supplied screw and ensure that the cable from the wind sensor is correctly plugged in otherwise data transmission errors could occur.

  • Page 33: Care And Maintenance

    The Rain Sensor (optional) Horizontal panel For best results, the rain sensor should be securely mounted onto a horizontal surface about 39.37” (1 meter) above the ground (or higher) and in an open area away from trees or other coverings where rainfall may be reduced causing inaccurate readings. When securing into place, check that rain excess will not collect and store at the base of the unit but can flow out between the base and the mounting surface (test by pouring clean water).

    • Do not make any repair attempts to the unit. Return them to their original point of purchase for repair by a qualified engineer. Opening and tampering with the unit may invalidate their guarantee. • Never touch the exposed electronic circuitry of the device, as there is danger of electric shock, should it become exposed.
