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.
Thesystemcanexpandupto8thermometer&humiditysensorsandbecompatible
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
practicalstep-by-stepinstructions, as well as technical specifications and warnings
you should know about.

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. Makesure the engraved arrow on thethermo/hygro sensor casing towards the
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.
Puttheplasticdebrisfilterintheraincollector .
 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. Insertthe bottom of the wind sensorunit into the
windvane 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.
SET UP TRANSMITTER BOX
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 offtherubberstopper from the cable slot.
3. Insertallthesensorcablesthroughthecableslot.
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.

TRANSMITTER BOX-BATTERY INSTALLATION
The solar panel on transmitter box is an energy saving feature, which is an
environmentally friendly way to provide power to the sensors and prolongs battery
life. It can entirely provide power to the supplied rechargeable battery. Sensors
can operate entirely on the rechargeable battery power. Locate the transmitter box
under direct sunlight for power supplying by the solar panel.
Therechargeablebatteryfromfactoryisnotwithfull
battery for long time use and it probably becomes
low battery during the shipping. We recommend
you to charge it for several hours by the connected
solar panel.
You can also purchase a power adapter separately
for directly providing power to the transmitter box.
The output voltage of the power adapter is 3V.
Route the adapter cable through the cable slot.
Please check the solar panel connection. If it
is not firmly plugged, please re-connect the
solar panel:
Plugtheend of color-corded connector into corresponding socket inthetransmitter
box as shown below and place the wires neatly inside the box.
To install the rechargeable battery:
Insert the battery into the battery compartment, matching the polarity +/-.

CHANNEL SETTING
Your weather station system can expand with up to 8
sets of thermometer & humidity sensors, and one of
each of wind and rain sensors, which share one main
unit to display the weather readings. You can number
each transmitter box with an independent channel ID
(1-8) by sliding the switches.
Please follow the below chart to adjust the sliding switches of SW1:

REMOVE SETTING
For removing the previous setting from the transmitter box, you can press RESET
and KEY at a time, then only release RESET, red light flashes 5 times. Then
release KEY. The channel setting and calibrated wind direction are all removed
from the transmitter box.
LED LIGHT INDICATOR
There are three colors of LED lights in transmitter box, green, red and blue.
Different color combinations indicate different status.
Light Color Operations

Blue flashes A normal transmission (WMR300A)
Green flashes A normal transmission (WMR300)
SENSORS INSTALLATION
You have three options to install the sensors.
The transmitter box is capable of transmitting data wirelessly an approximate
operating range of 300m (1000 feet). Ideal placements for the sensor would be
in any location on the roof of a building that is in an open area away from trees
or other obstructions preventing from the wind flow for an accurate reading.
Additionally, locate the transmitter box at the direct sunlight for power supplying
by the solar panel.
Solar panel facing: If you reside in the:
North Southern Hemisphere
South Northern Hemisphere
 Make sure the temperature and humidity sensor should be located at least
1.5 meters above the ground surface to avoid the ground temperature affecting
accuracy of the temperature and humidity sensor.
Option 1: All sensors are installed on a pole.



 Please take off the rain collector before installation and choose a pole with
the diameter that is about 32-45mm.
1. Locateone U-bolt without flat washers, lockwashers and hex nuts into thegap
of the rain gauge (Figure 1).
2. Let the pole fully approach to the inner of the U-bolt (Figure 2).
3. Locate the other U-bolt without flat washers, lock washers and hex nuts into
the screw holes of the rain gauge (Figure 3).
