• The batteries in the outdoor sensor are weak or empty. Insert new batteries into the outdoor
sensor on a trial basis.
• The distance between the weather station and the outdoor sensor is too large. Change the
location of the weather station or outdoor sensor.
• The included outdoor sensor is preset to Channel 1 (this cannot be changed).
For the outdoor sensors available as accessories, the transmission channel can be set. Set
channel 2 or 3 here. Observe that each outdoor sensor must be set to a different channel.
Otherwise, they would interfere with each other.
• Very low outdoor temperatures (less than -20 °C) decrease battery performance (this effect
will be stronger for rechargeable batteries). This reduces the range or the outdoor sensor will
no longer work properly.
• Another transmitter on the same or close frequency interferes with the radio signal of the
outdoor sensor. It may be helpful to reduce the distance between the weather station and
outdoor sensor or to choose another installation site.
• Objects or shielding materials (metallised insulating glass windows, steel reinforced concrete
etc.) are obstructing the reception. The weather station is too close to other electronic devices
(TV, computer). Change the location of the weather station and the outdoor sensor.
No DCF reception
• Objects or shielding materials (metallised insulating glass windows, steel reinforced concrete
etc.) are obstructing reception. The weather station is too close to other electronic devices
(TV, computer), cables or mains sockets. Change the location of the weather station.
• Setting up the weather station in the basement or similar will result in a weak DCF signal
and is therefore not possible. The same applies if the weather station is too far away from
the DCF transmitter.
Set the time and date manually; see chapter 12. a).
• The weather station performs several reception attempts for the DCF signal every day (at
midnight, 3:00 am, 6:00 am and noon). Therefore, just leave the weather station standing for
a day; maybe reception will be free of interference at another time of the day.
A single successful reception per day will keep the deviation of the quartz clock in the weather
station below a second.
• Start a search for the DCF signal again; please see chapter 10. b.).
