A – LED of signal transmission from the sensor
B – outdoor temperature and humidity
C – a hole to hang the device on the wall
CH – switching between sensor channel numbers (1, 2, 3)
°C/°F – temperature unit
Putting into operation
1. Insert batteries into the weather station (2× 1.5 V AA) first, and then into the wireless sensor (2× 1.5 V AAA). When
inserting the batteries make sure the polarity is correct to avoid damaging the weather station or sensor. Only use
alkaline batteries of the same type, do not use rechargeable batteries.
2. Place the two units next to each other. The weather station finds signal from the remote sensor within 3 minutes. If
the remote sensor signal is not detected, press and hold the CHANNEL button to repeat the search.
3. If the outdoor temperature value disappears from the display, press and hold the CHANNEL button on the weather
station. The weather station resets all values and repeats search for the sensor signal.
4. We recommend placing the sensor on the north side of the house. The range of the sensor may decrease substantially
in urban areas.
5. The sensor is resistant to dripping water, however, it should not be exposed to rain permanently.
6. Do not place the sensor on metallic objects, otherwise it will reduce its transmission range.
7. If low battery icon is displayed, replace batteries in the sensor or weather station.
Switch-over to another channel and connecting more sensors
1. Press shortly the CHANNEL button on the back side of the weather station to select the required sensor channel - 1,
2 or 3. Then press and hold the CHANNEL button; the icon starts flashing.
2. Remove the cover from the battery compartment and insert batteries (2× 1.5 V AAA)
3. Use the CH button to set the desired sensor channel No. - 1, 2, 3 which will be shown on the front panel display. Data
from the sensor will be loaded within 3 minutes.
4. If the sensor signal is not detected, remove the batteries and reinsert them.
Radio controlled clock (DCF77)
After registration, the weather station uses the wireless sensor to automatically search for the DCF77 signal for 7 mi-
nutes; icon D flashes.
During the search, no other data on the display will be updated and the buttons will be disabled (except SNOOZE/LIGHT).
Signal detected - the icon stops flashing and displays the current time with the DCF icon.
Signal not detected – DCF icon is not displayed.
Press and hold the button to repeat search for the DCF77 signal -.
Press and hold the button again to stop search for the DCF77 signal -.
DCF signal will be synchronised daily between 2:00 and 3:00 am.
In normal conditions (at a safe distance from sources of interference, such as television sets or computer monitors) the
capture of time signal takes several minutes.
If the weather station does not detect the signal, follow these steps:
1. Move the weather station to another location and try to detect the DCF signal again.
2. Check the distance of the clock from the sources of interference (computer monitors or television sets). It should be
at least 1.5 to 2 m during the reception of the signal.
3. When receiving the DCF signal, do not place the weather station near metal doors, window frames and other metal
structures or objects (washing machines, dryers, refrigerators, etc.).
4. In reinforced concrete structures (cellars, high-rise buildings, etc.), the DCF signal reception is weaker, depending
on the conditions. In extreme cases, place the weather station close to a window toward the transmitter.
Reception of the DCF 77 radio signal is affected by the following factors:
• thick walls and insulation, basements and cellars.
• inadequate local geographical conditions (these are difficult to assess in advance.
• atmospheric disturbances, thunderstorms, electrical appliances with no interference elimination, television sets and
computers located near the DCF receiver.
