• After the 3 minute search for the radio signal of the outdoor sensor has elapsed, the
base station will proceed with the search for the DCF signal.
The DCF signal is a signal broadcast from a transmitter
in Mainflingen (near Frankfurt am Main). Its range
covers up to 1500 km and, under ideal reception condi-
tions, even up to 2000 km.
The DCF signal contains the exact time and the date,
among other details.
Naturally, this also eliminates the hassle of manually
setting up summer and winter times.
• While the base station is searching for the DCF signal,
a radio tower icon flashes at the top between the time displays.
Do not place the base station next to electronic devices, metal parts, ca-
bles and so on. Also expect poor signal strength where metallised insulating
glass windows, reinforced concrete constructions, coated special wallpa-
per is used or in basement rooms.
• The capture and analysis of the DCF signal can take up to 7 minutes. Do not move
the base station during that time. Do not use any buttons.
After the base station has read the DCF signal correctly, the current time, the date
and the weekday appear in the display; the radio tower symbol stops flashing.
The synchronisation of the base station and DCF signal is done daily at 01:00, 02:00,
03:00, 04:00 and 05:00. One successful reception attempt per day already is enough
to keep the time deviation shown on the display below one second.
• During summer time, “DST” is shown below the radio tower symbol (DST = “Day-
light Saving Time” = summer time).
• If no current time is shown on the base station’s display after about 7 minutes, move
the base station to a different site. Then start another search for the DCF signal (see
chapter “Starting DCF reception attempt manually”) or set the time manually.
Installation/Setup
a) Base station
The base station can be set up on a level, stable surface. Protect valuable furniture
surfaces by using a suitable mat to prevent scratches.
Don’t place the base station near heaters; protect also from direct sunlight.
Otherwise, the ambient temperature will not be measured correctly.
b) Outdoor sensor
The outdoor sensor can be mounted on the wall through its rear opening using a nail,
screw or hook.
The outdoor sensor is intended for use in protected outdoor areas. It should
be placed so that it is not exposed to direct sunlight, since this can result in
a false temperature reading.
Precipitation falling on the sensor will also lead to a false temperature read-
ing, since this cools the housing. Never dip the outdoor sensor in or under
water; this will destroy it!
Starting DCF reception attempt manually
Press and hold the “-” button (3) for 3 seconds. This will initialise the search for the
DCF signal; the radio tower icon flashes (at the top between the time displays). The
reception attempt lasts up to 7 minutes; do not move the base station during this time,
and do not press any buttons.
You may also wait for a day, so that the attempt to catch the DCF signal can
happen at night, when a better reception of the DCF signal can be achieved.
To stop the reception attempt early, press the “-” button (3) again for 3 seconds.
If the DCF reception is impossible at the location of the base station, set the time
manually.
Searching for the outdoor sensor
If the outdoor sensor is not found, the bottom right of the display will show only dashes
instead of the outdoor temperature.
In case of reception problems, reduce the distance between the outdoor
sensor and the base station or select a different installation location. Also
check the outdoor sensor’s batteries and replace with new ones, if neces-
sary.
In order to initiate the search for the available outdoor sensors manually, press and
hold the “CHANNEL” button (4) for 3 seconds.
The reception symbol flashes in the bottom right in the area of the outdoor tempera-
ture display. This process lasts approx. 3 minutes. Do not press any button during this
time. Do not move the base station.
Setting the time of day manually
• To start the setting mode, press and hold the “MODE” button (7) for approx. 3 sec-
onds. Then the year flashes in the display.
• Set the year by pressing the “+” (1) or “-” (3) buttons.
For a quick adjustment, press and hold down the corresponding button for a
bit. This also applies for the settings described below.
If no button is pressed for approximately 7 seconds, the base station auto-
matically leaves the setting mode and the settings are saved.
• Briefly press the “MODE” (7) button, and the month flashes.
• Set the month by pressing the “+” (1) or “-” (3) buttons.
• Briefly press the “MODE” (7) button, and the date flashes.
• Set the date by pressing the “+” (1) or “-” (3) buttons.
• Briefly press the “MODE” (7) button, and the language for the weekday flashes.
“EN” = English
“IT” = Italian
“FR” = French
“DU” = Dutch
“SP” = Spanish
“DA” = Danish
“GE” = German
• Set the desired language by pressing the “+” (1) or “-” (3) buttons.
• Briefly press the “MODE” (7) button, and the hours will blink.
• Set the hours using the “+” (1) or “-” (3) buttons.
• Briefly press the “MODE” (7) button, and the minutes will blink.
• Set the minutes using the “+” (1) or “-” (3) buttons.
• Briefly press the “MODE” (7) button, and the time zone flashes.
• Set the desired time zone in the range of -12 to +12 hours by pressing the “+” (1) or
“-” (3) button.
• Press the “MODE” (7) button briefly to end the setting mode (alternatively, do not
press any button for 7 seconds).
Switch between 12h / 24h format
Briefly press the “+” button (1) to switch between the 12h and 24h modes. In the 12h
mode, “AM” is displayed to the left of the time during the first half of the day, and “PM”
in the second half.
Switching between temperature units °C/°F
Briefly press the “-” button (3) in order to change between the temperature unit °C
(degrees Celsius) and °F (degrees Fahrenheit).
Alarm function
a) Switching the alarm function on/off
Briefly press the “ALARM” button (8) to switch the alarm function on or off. When the
alarm function is switched on, a small clock symbol appears between the hour and
minute display of the time.
b) Setting the alarm
• Press and hold the “ALARM” button (8) for about 3 seconds; the hours of the alarm
time flash.
• Set the hours of the alarm time with the “+” (1) or “-” (3) buttons. For quick adjust-
ment, press and hold down the corresponding button for a little longer.
• Briefly press the “ALARM” button (8); the minutes of the alarm time flash.
• Set the hours of the alarm time with the “+” (1) or “-” (3) buttons. For quick adjust-
ment, press and hold down the corresponding button for a little longer.
• Briefly press the “ALARM” button (8) to save the settings and exit the setting mode.
c) Enabling the snooze function and/or exiting the alarm
• At the set alarm time, an alarm signal is activated; in addition, the bell symbol flash-
es.
• When the “SNOOZE/LIGHT“ (2) button is pressed, the alarm signal will be inter-
rupted for 5 minutes. During this time, the clock symbol and the “ZZ” symbol under
the clock symbol flash.
Afterwards, the alarm signal will restart.
This process may be repeated several times in a row.
• In order to end the alarm signal (or the snooze mode), briefly press any other button.
