INTRODUCTION
Thank you for selecting the Oregon Scientific™ Ultra-precision Professional
Weather System (WMR300 / WMR300A).
This system can provide you with weather information through several sensors
with high level of accuracy. All sensors are cabled to a transmitter box which is
battery and solar powered operated for wirelessly communicating and displaying
the data on an indoor LCD main unit.
This system remembers the data for a time range for you to monitor and analyze
the weather status. You can also export the data to PC by cable and manage and
analyze the data systematically.
The system can expand up to 8 thermometer & humidity sensors and be compatible
with other weather sensors. To purchase additional sensors, please contact your
local retailer.
Please keep this manual handy as you use your new product. It contains
practical step-by-step instructions, as well as technical specifications and warnings
you should know about.

installation direction of the transmitter box.
2. Align three screw holes on the rain gauge with the three double end studs on
the thermo/hygro sensor casing.
3. Tightly twist the type B screws into the double end studs to make sure the
connection is firmly.
4. Put the rain collector on the rain gauge
aligning the tipping with the holes, and
then twist clockwise to secure it tightly.
5.
Put the plastic debris filter in the rain collector
.
Cut away the cable tie on the tipping
bucket before using.
SET UP WIND SENSOR
The wind sensor takes wind speed and direction readings.
1. Loosen the screws in the wind cups and wind vane.
2. Insert the top of the wind sensor unit into the wind cups securely with some
pressure and then twist the screw tightly.
3. Insert the bottom of the wind sensor unit into the
wind vane securely with some pressure and then
twist the screw tightly.
There is a rubber washer around the top of
the wind sensor for preventing from hard touching
during installation. You can move up the rubber
washer a little bit before inserting the wind cup.

INSTALLATION
Please prepare some tools before starting your installation. You may need some
types of screw drivers, wrenches or an electric drill.
SET UP RAIN SENSOR & THERMO / HYGRO SENSOR
The rain gauge collects rain and takes rainfall readings. The transmitter box can
wirelessly transmit data to the main unit.
1. Approach the mounting ring of the transmitter box to the rain gauge, and align
mounting ring with the bottom of the hole of the rain gauge.
2. Insert the mounting insert into the mounting ring of the transmitter box through
the hole of the rain gauge with some pressure. A click sound can be heard.
The transmitter box contains sophisticated electronic parts, so you must
treat it with care.
CABLE CONNECTIONS
It is better you connect the cables of each sensors
to the transmitter box before positioning the pole.
1. Unscrew to open the transmitter box.
2. Take off the rubber stopper from the cable slot.
3. Insert all the sensor cables through the cable slot.
4. Plug each sensor cable into corresponding
socket that has name below the socket for
recognition. A click sound can be heard.
5. Return the rubber stopper to the cable slot.
