COMMISSIONING
Main unit
The main unit can be powered by the AC adaptor or batteries. Use only the delivered AC adaptor.
Battery installation
1) Remove the battery compartment cover on the rear side of the main unit.
2) Insert 2 pcs AAA batteries (micro) –observe the correct battery polarity.
3) Close the battery compartment.
Connecting the AC adaptor
1) Connect the AC adaptor plug into the socket on the rear side of the main unit.
2) Connect the other side of the AC adaptor to a mains socket.
After the power supply is connected, the display shows all segments for 3 seconds and a beep sounds.
Then, the wireless sensor signal reception icon flashes on the display for the outdoor values (OUT)
channel number for 3 minutes.
Wireless sensor GARNI 029
1) Remove the battery compartment cover on the rear side of the wireless sensor.
2) Set the required channel using the switch in the battery compartment.
3) Insert 2 pcs AA (mini) batteries –observe the correct polarity.
4) Push the TX button. The temperature value measured by the wireless sensor is displayed on the
corresponding channel on the main unit display.
5) Close the battery compartment.
Once the connection of the main unit to the wireless sensor is established, place the main unit
and the wireless sensor in the desired location within the range of the wireless sensor signal.
Using multiple wireless sensors
The main unit allows to connect up to 3 wireless sensors which can be placed at different spots. Each
wireless sensor must be assigned its own channel number (1, 2 and 3).
1) Place the main unit and the wireless sensor next to each other.
2) Remove the battery compartment cover on the side of the wireless sensor.
3) Assign a number to each wireless sensor using the switch so that the numbers are unique.
4) Insert 2 pcs AA (mini) batteries, observe the correct polarity. Then push the TX button. The display
of the main unit will display the temperature value measured by the wireless sensor on the respective
channel
5) To display the readings from a given wireless sensor, select the desired channel on the main unit
using the +button.
The reception of the wireless sensor signal can be also started manually by pushing and holding button +
for 3 seconds.
Placement of the weather station
Main unit
Select the location of the main unit away from direct sunlight. Test the connection to the wireless sensor
before final installation. If there is a problem with the signal reception, select another location. You may also
put the main unit on a flat surface. Placement near TVs, monitors, computers, etc. may negatively affect the
reception of the DCF-77 signal and the wireless sensor signal.
Wireless sensor
Place the wireless sensor away from direct sunlight not to compromise the measurement. Placement
outdoors, at the northern wall is recommended. Obstacles such as walls, concrete, metal structures and
large objects reduce the signal range. Position the wireless sensor vertically for optimum signal
transmission. Maximum open space signal range id 60 meters.

5
The signal range may be affected by obstacles (walls, trees) and other electrical devices (TVs, monitors,
etc.).
Time controlled by the DCF-77 radio signal
The weather station is equipped with the DCF-77 time/date control signal receiver, the signal is
broadcasted by a transmitter from Frankfurt am Main, Germany, with a range of about 1500 km. When
outside this range, the time and date can be adjusted manually. The time and date are adjusted every day.
When the AC adaptor connector is connected to the main unit, the display lights up, all display segments
are briefly displayed, and a beep sounds and the wireless sensor signal reception commences.
After the connection with the wireless sensor has been established, the reception of the DCF-77 is
commenced, indicated by flashing icon . This process may take several minutes. The display will be off
during the reception of the DCF-77 signal and the functionality of the main unit will be limited. Only the
touch button will function. To terminate the DCF-77 signal reception, press the –button and hold
for 2 seconds.
When the signal is received successfully, the display shows the current time, date and signal reception icon.
The icon shows the signal reception strength, the more bars the better the signal. The weather station
will automatically receive the DCF-77 signal for time adjustment every day at 1:00, 2:00 and 3:00. If the
reception is unsuccessful, it will be attempted again in another hour, five times in total. The received time is
compared with the time on the main unit and adjusted if necessary. For better signal reception, place the
main unit near a window.
If the DCF-77 signal is not received (icon is not displayed), reception will be interrupted, and it will be re-
attempted in an hour until the DCF-77 signal is received successfully.
Note:
The received DCF-77 time adjustment signal strength may be affected by the geographical location or the
premises where the weather station is located.
For better reception, the main unit should be placed on a flat non-metallic surface, near a window on the
upper floor of your house away from electrical appliances such as a TV, computer, etc.
Manual reception of the DCF-77 signal
Press buttons +and –simultaneously. The display backlight is turned off, icon flashes and a search for
DCF-77 is started manually. If the reception is unsuccessful, the icon disappears, and the time is not
adjusted automatically. After the signal is received successfully, the icon is displayed, time and date are
adjusted, even if they were manually set before.
To terminate the DCF-77 signal reception, press the –button and hold for 2 seconds.
No data on display
Reception of the DCF-77 signal not successful
1.
Check that the DCF-77 is available at your location.

Weather forecast
The forecast is based on the change in barometric pressure, generally speaking when the barometric
pressure rises, the weather improves and vice versa. The forecast accuracy is 75% and is valid for the next
12 to 24 hours for the area within a radius of 30 to 50 km.
The weather forecast uses six icons –sunny, somewhat cloudy, cloudy, precipitation, heavy rain and snow.
Sunny
Somewhat
cloudy
Cloudy
Precipitation
Heavy rain
Snow
Note: the snow icon replaces the precipitation or heavy rain icons if the outdoor temperature from
the channel 1 sensor is below -4°C. If the channel 1 is not used, it is the temperature from
channel 2 sensor, if channel 2 is not used, then it is the temperature from the channel 3
sensor
Weather trend arrows
The weather station updates the weather trend arrows according to the barometric pressure reading
Barometric pressure increased
Barometric pressure unchanged
Barometric pressure decreased

7
E.g.: the weather forecast indicates rain, the barometric pressure drops abruptly and quickly, therefore the
probability of heavy rain is higher.
Temperature trend arrows
The main unit displays the trend icons based on the temperature readings.
Temperature increased
Temperature unchanged
Temperature decreased
DISPLAYING THE MAX. AND MIN. TEMPERATURE READINGS
Press the MEM button repeatedly to display the maximum and minimum temperature readings, separately
for each channel in case more wireless sensors are in use. Select the required channel with the +button.
To delete the stored maximum and minimum temperature readings, display the maximum or minimum
values and press and hold the –button for 3 seconds. The memory is also automatically erased at 00:00
every day.
FROST INDICATION
As soon as the outdoor temperature is between -1°C and +3°C, the icon will flash

- in the outdoor temperature (OUT) area –batteries of the wireless sensor are empty
CHARGING MOBILE DEVICES
The weather station has USB port for charging mobile devices You can only charge mobile devices when
the weather station is powered by the AC adaptor.

9
The charging commences automatically when the mobile device is connected. Monitor the charging
process and disconnect the cable from the USB port when the mobile device is charged.
Notice: The USB port can only supply a charging current of 1,000 mA.
TROUBLESHOOTING
problem / situation solution
DCF-77 signal not received relocate the main unit; start the manual signal search;
set the time and date manually
instead of temperature reading temperature readings are outside the measurable range
the display shows: H.HH or LL.L
the weather station is not working correctly reset the factory settings of the main unit by removing
