It is recommended to plug in the power supply to reduce the battery
consumption and extend the service life.
Note: The sensor array must be powered and updating before powering up the console, or the
console will time out searching for the sensors. Power the console last.
Make certain the weather station sensor array is at least 3m away from the console and within
30m of the console. If the weather station is too close or too far away, it may not receive a proper signal.
Remove the battery door on the back of the display, as shown in Figure 11. Insert three AAA (alkaline
or lithium)) batteries in the back of the display console. The display will beep once and all of the LCD
segments will light up for a few seconds to verify all segments are operating properly.
Note: The character contrast is best from a slightly elevated viewing angle.
Figure 8
Replace the battery door, and fold out the desk stand and place the console in the upright
position.
The unit will instantly display indoor temperature, humidity, pressure, tendency, moon
phase, and time. The wind speed, wind gust, wind direction, rain, outdoor temperature and
humidity will update on the display within a few minutes. Do not Press any menu buttons
until the outside transmitter report in, otherwise the outdoor sensor search mode will be
terminated. When the outdoor transmitter data has been received, the console will
automatically switch to the normal mode from which all further settings can be performed.
While in the search mode, the remote search icon will be constantly displayed.
Note: The power adapter is intended to be correctly oriented in a vertical or floor
mounted position. The prongs are not designed to hold the plug in place if it is plugged into
a ceiling, under-the-table or cabinet outlet.

seconds when powered up. Conversely, if the power adapter is not plugged in, BL OFF
will be displayed.
3.4.2Sensor Operation Verification
The following steps verify proper operation of the sensors prior to installing the sensor
array.
1. Verify proper operation of the rain gauge. Tip the sensor array back and forth several
times. You should hear a “clicking”sound within the rain gauge. Verify the rain reading on
the display console is not reading 0.00. Each “click”represents 0.3mm of rainfall.
2. Verify proper operating of the wind speed. Rotate the wind cups manually or with a
constant speed fan. Verify the wind speed is not reading 0.0.
3. Verify proper operation of the indoor and outdoor temperature. Verify the indoor and
outdoor temperature match closely with the console and sensor array in the same location
(about 3m apart). The sensors should be within 2°C (the accuracy is ±1°C). Allow about
30 minutes for both sensors to stabilize.
4. Verify proper operation of the indoor and outdoor humidity. Verify the indoor and
outdoor humidity match closely with the console and sensor array in the same location

10
(about 3m apart). The sensors should be within 10% (the accuracy is ±5%). Allow about
30 minutes for both sensors to stabilize.
4.Weather Station Installation
4.1 Pre Installation Check. Before installing your weather station in the permanent
location, we recommend operating the weather station for one week in a temporary
location with easy access. This will allow you to check out all of the functions, insure
proper operation, and familiarize you with the weather station and calibration procedures.
This will also allow you to test the wireless range of the weather station.
4.2 Location Survey
Perform a site survey before installing the weather station. Consider the following:
1. You must clean the rain gauge once per year and change the batteries every year.
Provide easy access to the weather station.
2. Avoid radiant heat transfer from buildings and structures. In general, install the sensor
array at least 5’ from any building, structure, ground, or roof top.
3. Avoid wind and rain obstructions. The rule of thumb is to install the sensor array at least
four times the distance of the height of the tallest obstruction. For example, if the building
is 6m tall, install 4 x 6m = 24m away. Use common sense. If the weather station is installed
next to a tall building, the wind and rain will not be accurate.
4. Wireless Range. The radio communication between receiver and transmitter in an open
field can reach a distance of up to 100 m, providing there are no interfering obstacles such
as buildings, trees, vehicles, high voltage lines. Wireless signals will not penetrate metal
buildings. Most applications will only reach 30m due to building obstructions, walls and
interference.
5. Radio interference such as PCs, radios or TV sets can, in the worst case, entirely cut off
radio communication. Please take this into consideration when choosing console or
mounting locations.
4.3 Best Practices for Wireless Communication
Wireless communication is susceptible to interference, distance, walls and metal barriers.
We recommend the following best practices for trouble free wireless communication.
1. Electro-Magnetic Interference (EMI). Keep the console several feet away from
computer monitors and TVs.
2. Radio Frequency Interference (RFI). If you have other 433 MHz devices and
communication is intermittent, try turning off these other devices for troubleshooting
purposes. You may need to relocate the transmitters or receivers to avoid intermittent
communication.
3. Line of Sight Rating. This device is rated at 100 m line of sight (no interference,
barriers or walls) but typically you will get 30 m maximum under most real-world
installations, which include passing through barriers or walls.
4. Metal Barriers. Radio frequency will not pass through metal barriers such as aluminum
siding. If you have metal siding, align the remote and console through a window to get a
clear line of sight.
The following is a table of reception loss vs. the transmission medium. Each “wall”or
obstruction decreases the transmission range by the factor shown below.
Medium

5.Final Installation of Sensor
Integrated outdoor transmitter installation.
Professional Wireless Weather Station can be used in both the Northern and Southern
Hemispheres.
Prior to installation, you will need to calibrate the wind direction.
5.1. Northern Hemispheres (NOR).
The cardinal directions (N, S, E, W) molded on the body of the outdoor sensor are
indicators for the Northern Hemisphere only.
Step 1:There is a “S” indicator on the wind vane that indicates South, as shown in Figure
14. Align this “S” marker in the direction of South.
Step 2: Console operation is set to Northern Hemispheres ( NORin the time area) in
Location division.
Note: There are four alphabet letter of “N”,”E”,”S”and “W” around the wind
direction, representing for the direction of North, East, South and West. Wind direction
sensor has to be adjusted so that the directions on the sensor are matching with your real
location. Permanent wind direction error will be introduced when the wind direction sensor
is not positioned correctly during installation.
Northern Hemispheres
Figure 14

12
Southern Hemispheres
5.2. Southern Hemispheres (SOU).
For Southern Hemisphere installations, ignore these(N, S, E, W) and face the solar panel
to the North (and in a sunny position) when installing the Integrated outdoor transmitter.
Step 1: Install the Integrated outdoor transmitter and face the solar panel North.
Step 2: Console operation is set to Southern Hemispheres ( SOU in the time area) in
Location division.
Note: Console has to be location division setting so that the directions on the sensor
are matching with your real location. Permanent wind direction error（read approximately
180º）will be introduced when the wind direction sensor is not positioned correctly during
installation.
Fasten the integrated transmitter to mounting pole brackets with foot-mounting, two ￠3
bolts and M3 nuts , as shown in Figure 15

9. Other Console Features

19
The following section describes additional features and display icons.
9.1 Weather Forecasting
Note: The weather forecast or pressure tendency is based on the rate of change of
barometric pressure. In general, when the pressure increases, the weather improves (sunny
to partly cloudy) and when the pressure decreases, the weather degrades (cloudy to rain).
The weather forecast is an estimation or generalization of weather changes in the next 24 to
48 hours, and varies from location to location. The tendency is simply a tool for projecting
weather conditions and is never to be relied upon as an accurate method to predict the
weather.
