and on, the user is encouraged to try to correct the interference by one or
more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different from that to
which the receiver is connected.
• Consult DIG technician for help.
WARNING:
the user should make no field changes or modifications to the
LEIT WWS or LEIT WWSE weather stations. All adjustments and changes
must be made at DIG’s facility under the specific guidelines suggested in our
instruction manual. Any tampering or modification to the equipment will void
the users authority to operate the unit, render the equipment in violation of
FCC part 15, and will void the warranty.

Features
• Power is provided by an efficient photovoltaic module (PVM) and
microelectronic management system fueled by ambient light (solar)
• Weather data transmitted from the weather station is stored by the
controllers and reviewable by LEIT RC2ET handsets
• The weather station ID number enables any controller in range to
differentiate among multiple weather stations allowing the controller to
receive information from several weather stations
• Based on user input and information collected from the weather station
sensors, a LEIT-2ET controller performs the calculations needed to override
or adjust the daily scheduled irrigation program to compensate for
evapotranspiration (ET)
• Environmentally friendly, utilizes RoHS compliant components
• The LEIT weather stations utilize radio frequency in the ISM band 902-928
MHz (866 Hong Kong, 868 International) CE, IC, FCC certified, Australia and
Hong Kong compliant
• The LEIT weather station’s electronic components and sensors are
completely waterproof
• The rain gauge is a self-emptying tipping bucket reading rainfall in 0.01 inch
(.254 mm) increments
• The LEIT weather station’s three-plate radiation shield is specially designed
to protect the sensors from reflected and radiated heat
• The LEIT WWS and LEIT WWSE weather stations can provide information
to the LEIT ET controllers to completely stop irrigation if it is raining,
freezing or too windy
• Current weather data is provided to LEIT-2ET controllers daily, every hour,
during daylight hours only
• The weather stations function both day and night in any weather and in
most outdoor locations and only transfer weather data during daylight hours
• Rugged and lightweight plastic construction
• Three-year manufacturer’s warranty
