LOW BATTERY CONDITION DISPLAY
The weather station displays the low battery condition symbol to remind you the batteries of the weather station or the outdoor sensor need to be exchanged.
• Weather station low battery condition display: within indoor area of the display
• Outdoor sensor low battery condition display: in the outdoor area of the display
WIRELESS CONNECTION TO THE OUTDOOR SENSOR
- Press the key "CH" to select a channel. You can read the data of up to 3 sensors at one weather station.
- Press and hold the key "CH" for 3 seconds to search for an outdoor sensor.
RECEPTION OF THE RADIO-CONTROLLED SIGNAL
- The DCF radio signal search starts automatically about 3 minutes after the battery exchange. The “signal is flashing.
- Press the "Λ•MEM" and "v•HISTORY" button for more than 3 seconds to enter or quit the Radio controlled signal reception
- The clock synchronizes with the DCF radio signal automatically and daily from AM 1:00 to 3:00 to correct potential time deviations each hour. If the synchronization is unsuccessful ("radio tower" symbol disappears), a further synchronization attempt is made at 4:00 and 5:00 until completed successfully. This process is repeated up until 5:00 AM. If still no success, daily reception stop.
INFORMATION
• The flashing “▲” symbol stands for DCF radio signal reception started.
- Continuous “↑” symbol stands for DCF radio signal reception successful.
- Please observe a minimal distance of 2.5 meter to sources of interference such as televisions or computer screens.
- The radio signal reception is weaker in rooms with concrete walls e.g. in the basement and in office buildings. For extreme cases, please put the clock near a window.
- There are less atmospheric disturbances at night. A radio time signal reception is usually possible at that time. One synchronisation per day is sufficient to keep the time display accuracy at 1 second.
TIP
You can adjust the time manually in case the clock cannot receive the DCF radio signal due to interferences, large distance to the sender, obstructions like mountains, etc. As soon as the radio signal can be received, the clock will be adjusted automatically. The radio signal sender coverage is up to 1.500km distance from Frankfurt/Main.
ENVIRONMENT FRIENDLY DISPOSAL
The European Directive 2002/96/EC on Waste Electrical and Electronic Equipment – WEEE – requires that old household electrical appliances must not be disposed of in the normal unsorted municipal waste stream. Old appliances must be collected separately to optimise the recovery and recycling of the materials they contain and reduce the impact on human health and the environment.

The crossed out "wheeled bin" symbol on the product reminds you of your obligation that when you dispose of the appliance, it should be separately collected. Contact your local authority for information concerning the correct disposal of your old appliance.
