lnsert 2xLR6 (AA size) batteries into the transmifter, the LED located in the back of the rain collector will
illuminate for 4 seconds before going off and then the item -will function normally. The transmitter will
make a data transmission which will start the radio mntrolled time reception routine. lf the time signal is
detected correctly, the LED will start to flash 5 times, and then the LED will be pn for 20s, indicating that
the time signal his been found conectly. When the time signal is bad and reception is not possible, the
transmitteiwill terminate radio controlled time reception within one minute and resume normal mode.
When there is a data transmission the LED will be on for 20ms. During the radio controlldd time
reception period, there is no transmission and normal transmission wilt only resume after the reception
routine is complete. The longest time for radio controlled time reception is 5 minutes.

Receiver /lndoor unit
After inserting the batteries into the Weather Station, all LCD segments will be turned on for a few
seconds, all possible display segments are turned on for checking.
After this, the weather station will make initial measurements and start to register the transmitter (the
radio reception icon will be turned on). Do not press any key before the outdoor sensor data is received,
otherwise the outdoor sensor learning mode will be terminated. When the outdoor transmitter has been
registered, the base station will automatically switch to the normal display mode from which all fu(her
settings can be performed by the user.
lf no RCC signal is detected in the initial setup, the transmitter will try once every two hours to get an
RCC signal until a signal is received. Once the transmitter receives ine RCC signal it will transmit the
signal to the monitor. On the monitor the RCC tower icon will be displayed, if the monitor does not
receive the RCC signal or loses the signal continuously for 12 hours the RCC icon will not be displayed.
Note for RCC siqnat:
The best condition for reception is at night, betvveen midnight and 6:00am - when there is less
atmospheric interference.
Note:
lf the b_atteries are changed on the transmitter, then the receiver will be resynchronized to the transmitter
within 3 hours. lf you want to shorten the receiving dpta time, the base stati-on has to re-install the battery
so that it can have the new security code right way, however, the previous weather data and alarm value
settings in the receiver will be lost.
Nofe.'
Commonly the radio communication between receiver and transmitter in the open field can reach a
distance of up to 330 feet providing that there are no interfering obstacles such as buildings, trees,
vehicles, high voltage lines, etc.
Radio interferences such as PC screens, radios or TV sets can, in bad cases, entirely cut off radio
communication- Please take this into consideration when choosing standing or mounting locations.
Mounting
Before placing and installing all components of the weather station at there final destination, please set
up the weather station with a1l parts being nearby for testing the correct function. If e.g. there appear to
be problems with the 433 MHz radio transmission, they can mostly be overcom-e by moving the
mounting locations.
Transmitter (thermo-hygro sensor), rain collector, wind direction sensor have been mounted onto the
mast. You just need to assemble the wind cups attached_
Attaching the Wind Gups
1. Push the wind cups onto the anemometer's stainless steel shaft.
2. Use the Allen wrench provided to tighten the set screw on the side of the wind cups.
3. Spin the wind cups. lf the wind cups spin freely, the anemometer is ready and can be installed.

Wind Speed Calibration
Wind speed is the most sensitive to installation constraints. The weather station should not be located
close to buildings, trees or other obstructions.
Many installations are not perfect and installing the weather station on a roof can be difficult..Thus, you
can calibrate for this error with a wind speed multiplier.
ln addiiion to the installation challenges, wind cup bearings (moving parts) wear over time.
Without a calibrated source, wind speed can.be difficult to measure. We recommend using a calibrated
wind meter and a constant speed, high Spebd fan.

Tem perature Cal ibrati on
Temperature errors can occur when a sensor is placed too close to a heai source (such as a building
structure, the ground and when placed in direct sunlight without proper shielding in hot weather
environments).
To calibrate temperature, we recommend a mercury or red spirit (fluid) thermometer. Bi-metal (dial)
other digital thermometers are not a good source and have their own margin of error. Using a local
weather staiion in your area is also a poor source due to changes in locaiion, timing (airport weather
stations are only updated once per hour) and possible calibration errors (many official weather stations
are not properly installed and calibrated).
Place the sensor in a shaded, controlled environment next to the fluid thermometer, and allow the sensor
to stabilile for 48 hours. Compare this temperature to the fluid thermometer and adjust the console to
match the fluid thermometer.
Humidity Calibration
H.umidity is a difficult parameter to measure accurately and drifts over time. Humidity errors can occur
When placed too close to the ground, near grass or other sources of humidity.
The hygrometer sensor utilizes a capacitol which varies as a function of humidity. Due to manufacturing
tolerances, the accuracy of the sensor is + 5%. To improve on this accuracy, the indoor and outdoor
humidity readings can be adjusted or calibrated from the display console.
To calibrate humidity, you will need an accurate source, such as a sling psychrometer or Humidipaks
One Step Calibration kit.
Rainfatl calibration
The Rain Collector is calibrated at the factory so the bucket tips (and records rainfall) foi each 0.01" (or
0.3 mm) of rain. To calibrate rainfall, we recommend a tube type rain gauge. Use a rain gauge with an
aperture of at least 4 inches. Any smaller and the readings obtained may not be accurate. Place the tube
type rain gauge directly next to the rain collector. Compare the totals on three storms. Based on ihis,
develop an average for how far off the readings are.
Do not compare rainfall readings to reading obtained from television, radio, newspapers, or neighbours'
readings. Such readings are not located in your specific environment and therefore are not an accurate
measurement of the weather readings taking place in your surroundings. The rain collector is carefully
tested at the factory to conform to the specifications lisied in the back of this manual.
The history rainfall calibration factor is applied to ihe running total, not individual tips. All of the rainfall
figures are calculated from the total number of tips recorded by the station since it was reset. The total is
multiplied by 0.3 to get a total in mm. This is then converted to inches if necessary by multiplying by
0.0393700787. The calibration multiplier is then applied to this, and this is the figure that remembers and
compares each time a new total is read from the station.
History Modes
- While in Normal Mode, press the HISTORY key to enter the History Mode.
- In the history mode, prgssing SET key will trigger the history clear procedure: the word "CLEAR" will

Battery life
Notes:
When the outdoor temperature is lower than -20'C, make sure the correct type of batteries are used to ensure
that the device can get enough power to maintain its function properly. Normal alkaline batteries are not to be
used when the outdoor temperature is lower than -20 "C, because the batteries discharging capability is
greatly reduced.
When out of the temperature range of 10-35t, the transmrtteis low battery indicator may show up abnormally
even if you change to new batteries because the low voltage test point will rise along with the temperature
drop under 10r. ln this case, you do not need to change thetransmitter batteries. The low battery
indicator will work normal when the outdoor temperature rises to 10-35c.
\H Please help in the preseruation of the environment and return used batteries to an authorized depot
,,ni.
