Fig. 3 Weather Forecast Symbols

The weather station distinguishes between four different weather symbols: Sunny, Cloudy, Overcast, Rainy.

The forecast via symbols relates to a period of 12 to 24 hours and indicates only a trend. For example, if it is currently cloudy and rain is displayed, it does not mean the weather station is malfunctioning, but rather that air pressure has dropped and worsening weather can be expected, though it may not necessarily be rain. The sun symbol is also displayed at night if it is clear and a starry night.

Display Backlight

Note! Permanent display backlight only functions when powered by the mains adapter.

For short-term activation of the display backlight when powered by batteries, press the LIGHT button on the front or the LIGHT/SNZ button on the rear.

Getting Started

• Place the base station and outdoor sensor on a table approximately 1.5 meters apart. Avoid proximity to possible sources of interference (electronics and wireless devices).
• Open the battery compartment on the outdoor sensor.
• Insert 2 new AAA 1.5 V batteries into the compartment. Observe correct battery polarity when inserting.
• Remove the protective film from the base station display.
• Connect the base station to power using the supplied mains adapter. Plug the connection connector into the socket on the base station and plug the adapter into the mains socket. Important! Ensure that the mains voltage in your network does not exceed 230 V! Other mains voltages could lead to product damage.
• A short beep will sound, and all segments will briefly light up. The display backlight will activate.
• The indoor temperature will appear on the base station display, and the base station will attempt to receive the outdoor temperature (the signal reception symbol ? will flash).
• If the outdoor temperature is not received, '--' will appear on the display. Remove any sources of interference.
• After receiving the DCF radio-controlled time, you can also manually initiate reception of the signal from the outdoor sensor. Press and hold the [Button Name] button for 3 seconds. The base station will attempt to receive the outdoor temperature signal again.

Receiving DCF Signal

• The clock will now attempt to receive the radio signal, and the DCF signal reception symbol will flash.
• If the time signal is received within 7 minutes, the radio-controlled time will be displayed, and the DCF signal reception symbol will remain on the display. No external values are transmitted during DCF radio-controlled time reception.
• If signal reception is not possible, you can also initiate it manually. Press the WAVE button.
• The DCF signal reception symbol will flash.
• The attempt to capture the signal is interrupted by pressing the WAVE button again. The DCF signal reception symbol will go out.
• DCF signal reception occurs daily from 1:00 AM to 5:00 AM. If the signal is not successfully received by 5:00 AM, further attempts will be made again at 1:00 AM.
• If the radio-controlled clock cannot receive the DCF signal (e.g., due to interference, transmission distance, etc.), the time can also be set manually. The DCF signal reception symbol will disappear, and the clock will then function as a normal quartz clock (see Manual Time and Calendar Setting).

DCF-77 Radio Signal

DCF-77 is a radio transmitter of encoded time signals, broadcast in the longwave band (77.5 kHz) with a range of approximately 1,500 km. This transmitter, located in Mainflingen near Frankfurt am Main, broadcasts and encodes the DCF-7 time signal from cesium atomic clocks at the Physikalisch-Technische Bundesanstalt in Braunschweig. The deviation of this time is less than 1 second per million years. This radio time signal automatically accounts for astronomically determined time corrections (summer and standard/winter time), leap years, and date changes. If your weather station is within the reception range of this transmitter, it will begin receiving and decoding this time signal, displaying the precise time year-round, regardless of summer or standard (winter) time.

The abbreviation DCF stands for: D (Deutschland = Germany), C (designation for the longwave band), and F (Frankfurt region).

Reception of this DCF-77 radio time signal depends on geographical and structural conditions. Under normal conditions, this signal can be received without problems up to a distance of 1,500 km from the transmitter in Frankfurt am Main (under ideal conditions, up to 2,000 km from this transmitter). At night, atmospheric disturbances usually have lower intensity, and reception of this signal is possible almost everywhere. A single reception during the day (or night) is sufficient for the weather station to maintain the set time with an accuracy of less than 1 second.

Under normal conditions (at a safe distance from sources of interference such as television receivers, computer monitors), capturing the time signal takes several minutes. If the weather station does not capture this signal (or if reception is disturbed), you need to check according to the following points:

1. Relocate the weather station to another place and attempt to capture the DCF-77 signal again.
2. The distance of the weather station from sources of interference, such as computer monitors or television receivers, should be at least 1.5 to 2 meters when receiving this signal. Do not place the weather station near metal doors, window frames, or other metal structures or objects (washing machines, dryers, refrigerators, etc.) when receiving the time signal.
3. In areas with reinforced concrete structures (basements, high-rise buildings, etc.), DCF-77 signal reception is weaker depending on conditions. In such cases, place the weather station near a window or orient its rear or front side towards the transmitter in Frankfurt am Main.

Inserting Batteries into the Base Station

• Open the battery compartment on the base station.
• Insert 2 new AAA 1.5 V batteries into the compartment. Observe correct battery polarity when inserting.
• Close the battery compartment again.
• If you require permanent display backlight or want to extend battery life, use the supplied mains adapter.
• Batteries function as a backup power source in case of a power outage.

Operation

• Important: Buttons cannot be used during reception of the outdoor temperature radio signal and the time signal.
• During operation, all successful entries are confirmed by a short beep.
• The product will automatically exit the setting mode if no button is pressed for an extended period.
• If you press and hold button ▲ or ▼ in setting mode, the reset will be faster.

Manual Time and Calendar Setting

Weather Forecast (Fig. 3)

The weather station distinguishes between four different weather symbols: Sunny, Cloudy, Overcast, Rainy.

The forecast via symbols relates to a period of 12 to 24 hours and indicates only a trend. For example, if it is currently cloudy and rain is displayed, it does not mean the weather station is malfunctioning, but rather that air pressure has dropped and worsening weather can be expected, though it may not necessarily be rain. The sun symbol is also displayed at night if it is clear and a starry night.

Placement and Mounting of the Base Station and Outdoor Sensor

• For the outdoor sensor, find a shaded location outdoors protected from precipitation. (Direct sunlight distorts measured values, and constant moisture unnecessarily stresses the electronic components).
• Place the base station with its stand in a living area. Thanks to the mounting device, you can also hang the unit on the wall. Avoid proximity to other electrical appliances (televisions, computers, cordless phones) and large metal objects.
• Check if the transmission of measured values from the outdoor sensor to the base station works at the chosen location (range in open space up to 60 meters); in case of solid walls, especially metal structures, the range of the outdoor sensor can be significantly reduced.
• If necessary, find a new location for the outdoor sensor and/or the base station.
• If transmission is functioning correctly, you can mount the outdoor sensor. The outdoor sensor can be hung on the wall or placed on a flat surface using the bracket on the rear.
