Operating Instructions
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 dam-
aging 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 will detect the remote sensor signal
within 3 minutes. If the remote sensor signal is not detected, press and hold the CH button to
repeat the search for the remote sensor signal.
3. If the outdoor temperature value disappears from the display, repeat steps 1 and 2.
4. We recommend placing the sensor on the north side of the house. The range of the sensor may
decrease substantially in areas with large number of obstacles. The sensor is resistant to dripping
water; however, it should not be exposed to sustained rain. Do not place the sensor on metal
objects as this reduces transmission range.
Radio Controlled Clock (DCF77)
After registering the wireless sensor, the weather station will automatically begin searching for DCF77
signal for 10 minutes – the icon will flash. After detecting the DCF signal, the icon will be displayed.
During the search, no other data on the display will be updated and the buttons will be disabled.
Signal detected – the icon stops flashing and the current time is displayed.
Signal not detected – the icon disappears. Press and hold the UP button to search for DCF77 signal
again.
To cancel searching for DCF77 signal, again shortly press the UP button.
DCF signal will be synchronised daily between 2:00 and 3:00 am.
Note: If the weather station detects DCF signal but the current time on the display is incorrect (e.g.
shifted ±1 hour), you must always set the correct time zone for the country where you are using the
station, see Manual Setting of Time and Date.
In standard conditions (at safe distance from sources of interference, such as TV sets, computer
monitors), the reception 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 DCF signal again.
2. Check the distance of the clock from 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 DCF signal, do not put the weather station in the proximity of 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.
Manual Setting of Time and Date
1. Press and hold the MODE button.
2. Use the UP/DOWN buttons to set: year – month – day – calendar language – time zone – 12/24 h
time format – hours – minutes.
3. Press MODE to move between the values.
Each press of button to switch or change settings is followed by a beep. This function
cannot be turned off.
English calendar abbreviations are as follows:
SUN – Sunday, MON – Monday, TUE – Tuesday, WED – Wednesday, THU – Thursday, FRI – Friday,
SAT – Saturday
