• When the display contrast fades or when the display light no longer works, the batteries of the
base station are flat and need to be replaced as described above.
• If the batteries in the outdoor sensor have lost their charge, a battery symbol will appear
both in the sensor’s display and beside the outdoor temperature gauge (A5). In this instance
change the outdoor temperature gauges batteries as described above.
• To ensure a long battery life, use only alkaline types.
Once the batteries are inserted, the base station starts searching for the signal of
the outdoor sensor. If you do not insert the batteries into the outdoor sensor during
this time period, the search for the sensor must be started manually. This step is also
necessary after a battery replacement in the outdoor sensor.
To start the sensor search manually, press and hold the SEARCH button (B6) on
the base station for three seconds. Then press the RESET button in the battery
compartment of the outdoor sensor with a sharp object (e.g. an open paper clip) in
order to activate the transmission function.
DCF reception
Immediately after the reception of the outdoor sensor’s signal, the device makes the first
attempt to receive the DCF signal. After a successful DCF reception, the clock is automatically
set to the current time.
The detection and interpretation of the DCF signal can take about five minutes. Do
not move the radio-controlled clock during this time. Do not press any buttons or
switches!
To cancel the DCF reception attempt, press and hold the – °C/°F button (B5) for
three seconds until the DCF symbol (A1) in the display goes out.
Bad reception can occur, for example, by metallised insulated glass, reinforced
concrete buildings, coated special wallpapers, proximity to electronic devices, or
installation in cellars.
If after 10 minutes the clock has not set the current time, change the location of the
radio clock and press the °C/°F (B5) button for three seconds until the DCF symbol
(A1) flashes in the display.
This will start a new reception attempt.
The reception attempt for the daily automatic
synchronisation with the DCF time is done at 03.00 AM.
One successful reception per day is sufficient to keep the
deviation to less than one second.
The DCF signal is encoded and transmitted via a DCF
transmitter in Mainflingen (near Frankfurt am Main).
Its range is up to 1,500 km and, under ideal reception
conditions, even up to 2,000 km.
Among other things, the DCF signal includes the precise
time (theoretical deviation of 1 second in a million years!)
and the date.
Naturally, this also eliminates the hassle of manually
setting summer and winter times.
Installation/set-up
The base station can be placed on a surface or hung on the wall:
• To set up the clock, fold out the support (C3) and place the clock on a level surface.
• Protect valuable furniture surfaces by using an appropriate underlay; otherwise, it may cause
scratches.
• For wall mounting, there are suspension eyes (C1) provided on the back of the device.
• Secure the clock in place with one or several screws that protrude a few millimetres from the
wall. Then hang the clock on the screw head with the suspension eyes (C1).
Outdoor sensor
• Secure the outdoor sensor in place with one screw or a nail that protrudes a few millimetres
from the wall. Then hang the sensor on the screw or nail head with the suspension eye on
the back of the device.
•
Alternatively the outdoor sensor can be opened. In order to do this you should flip open the
foot of the battery compartment.
The outdoor sensor is suitable 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 outdoor sensor will also lead to a
false temperature reading, since this cools the housing.
Therefore, we recommend you choose the installation place carefully, so the outdoor
sensor measures the correct temperature.
Never dip the outdoor sensor in or under water; this may destroy it!
DCF Time Adjustment
• After inserting the batteries and the reception of the outdoor sensor’s signal, the clock starts
searching for the DCF signal automatically. This is indicated by the flashing DCF symbol (A1)
on the top right in the display. Normally, the synchronisation process is completed within a
few minutes.
• As soon as the DCF signal is decoded, the DCF icon (A1) will appear continuously and the
current time and date are shown in the display.
• In normal mode, the clock starts a reception attempt at 03:00 AM. If the clock does not receive
any signal, the DCF icon (A1) goes out and the clock starts a new reception attempt at 04:00
AM, 05:00 AM and 06:00 AM.
• To start a manual reception attempt, press and hold the – °C/°F button (B5) for three seconds
until the DCF symbol (A1) flashes in the display.
If there is interference with the reception of the DCF signal, try to find a new location
and/or leave the clock near a window overnight.
At night the reception is better, so the clock is normally synchronised the next
morning.
The message DST (Daylight Saving Time) in the display, located beside the DCF
symbol, shows that the device is displaying the summertime setting.
Setting the time manually
If no keystroke is performed for more than 15 seconds while setting the time, the
clock exits the manual setting mode and returns to the previous screen.
• During the normal time mode, press and hold the MODE button (B1) until the hour display
flashes.
• Set the hours by using the b 12/24 (B4) and – °C/°F (B5).
•
Press the MODE button (B1) again. The minute display flashes.
• Set the minutes by using the b 12/24 (B4) and – °C/°F (B5).
•
Now set the seconds, the year, the date format, the month, the date, the language for the
weekday display and the time zone as described above.
The languages available for the weekday display are:
English (ENG), German (GER), French (FRA), Spanish (ESP), Italian (ITA), Dutch
(NET), Danish (DAN) and Russian (RU).
• Press the MODE button (B1) again to save the setting.
• The time zone setting needs only to be adjusted if the time zone differs from the DCF time
zone. Otherwise, leave the time zone at the value 00.
12/24 hour display
• Press the + 12/24 (B4) key to swap between the 12h and the 24h display.
Thermometer
The clock displays the room temperature in the indoor temperature display (A3) and the outdoor
temperature in the outdoor temperature display (A5).
• Press the - °C/°F (B5) button on the base station to switch between the display in °C and °F.
• Press the – °C/°F button in the battery compartment of the outdoor sensor to switch between
the display in °C and °F on the outdoor sensor.
• If the temperature lies outside the measurement range, the temperature displays show “LL.L”
(temperature too low) or “HH.H” (temperature too high).
Temperature alarm
The outdoor thermometer is equipped with an alarm function which indicates an alarm if the
outdoor temperature lies outside an adjustable temperature range.
• Press the ALERT button (B8) on the base station to switch the temperature alarm on or
off. When the temperature alarm is switched on, two arrow symbols are shown next to the
outdoor temperature display (A5).
•
Press and hold the ALERT button (B8) until the upper arrow flashes.
• Set the upper alarm temperature by using the b 12/24 (B4) and – °C/°F (B5).
• Press the ALERT button (B8) again and set the lower alarm temperature by using the buttons
+ 12/24 (B4) and – °C/°F (B5).
• Press the ALERT button (B8) again to save the settings.
• If the outdoor temperature exceeds or falls below one of the two alarm temperatures, an
alarm signal is emitted. To turn off the alarm signal, press the ALERT button (B8).
Alarm function
Programming the alarm time
• Press the MODE button (B1) once so that the alarm time (AL) is shown in the display.
