If the LED flashes repeatedly but your console isn’t picking up a signal
anywhere in the room, it could be related to one of the following causes:
• The DIP switches were not correctly set on the transmitter.
• Review the procedure on page 5.
• The ID was not correctly set on the console/receiver.
• Review the procedure on page 6.
• Reception is being disrupted by RF (radio frequency) interference.
• There is a problem with the console/receiver.
See “Contacting Davis Technical Support” on page 19.
Note: Remember to turn DIP switch #4 OFF when you’re finished testing wireless
transmission. If it is left ON, the blinking LED will reduce battery life significantly.
Choosing a Location to Mount the Station
Try to position your Leaf/Soil Station as follows:
• With the solar panel positioned for maximum exposure to the sun.
• Within transmission range of your Vantage Pro console.
• See “Range of Wireless Transmission” on page 8
• Within cable range of the sensors.
• Leaf Wetness Sensors come with 40’ (12 m) of cable standard and can be
extended up to 200’ (61m) using 6-conductor 26 AWG cable.
• Soil Moisture Sensors come with 15’ (4.6 m) of cable standard and can be
extended up to 1000’ (300m) using #18 gauge UF cable.
• Temperature Sensors come with 15’ (4.6 m) of cable standard and can be
extended up to 800’ (242m) using #24 AWG shielded cable or up to 1200’
(260m) using #22 AWG shielded cable.
Range of Wireless Transmission
The range of wireless transmission depends on many factors. For the best
reception, position the transmitter shelter and your console/receiver as close
together as possible.
The maximum range is up to 400' (120 m) in the line of sight, under optimal
conditions. Typical range under most conditions is 100' to 200' (30 to 60 m), but
this may be reduced by walls, ceilings, trees, foliage and radio-frequency
interference (RF). Cordless phones, baby monitors, and ham radios are
common examples of devices that can cause RF interference.
A metal roof or other large metal structure can interfere with the signal.
Aluminum siding, a furnace with metal ducts, and your refrigerator are
examples. Sometimes transmission between wireless units is obscured by
something you cannot identify, or by some obstacle that you can’t work
around. If necessary, consider using Wireless Repeater #7624 or #7625 to
strengthen the signal or increase the distance between the transmitter and the
console/receiver.
