Radio-controlled clock with indoor climate
Radio-controlled clock with indoor climate
7.1.1 Time zone setting
• In the setting mode you can make the time zone correction (-12/+12).
• The time zone correction is needed for countries where the DCF signal can be received but the time zone is different from the DCF time (e.g.
+1=one hour plus).
7.1.2 Day-of-week language setting
• In the setting mode you can set the day-of-the week language: German (GER), English (ENG), French (FRE), Spanish (SPA), Dutch (DUT), Italian
(ITA), Polish (POL) and Czech (CZE).
7.1.3 Temperature unit setting
• In the setting mode you can change between °C (Celsius) or °F (Fahrenheit) as temperature unit.
7.1.4 Seconds hand setting
• Press the
▼
/ SEC
button in normal mode, to activate or deactivate the second hand.
7.1.5 Date format setting
• Press the
▲
/ DM
button in normal mode to select the month/day sequence (American version) or day/month (European version).
7.2 Alarm time setting
• Press the
MODE/SET
button in normal mode, to enter the alarm mode.
• ALARM TIME and 7:00 (default) or the last adjusted alarm time appear on the display.
• Press and hold the
MODE/SET
button.
• The hour hand flashes.
• Press the
▼
/ SEC
or
▲
/ DM
button to adjust the hours.
Attention: 12:00 - 00:00 = PM!
• Confirm the setting with the
MODE/SET
button and set minutes in the same way.
• Confirm with the
MODE/SET
button.
• The set time appears on the display.
• Press the
MODE/SET
button again to return to the current time.
• The switch at the back allows you to choose between three different alarm functions (Mo-Fr., Mo-Sa, Mo-Su).
7.2.1 Activate and deactivate the alarm time
• To activate or deactivate the alarm function press the
AL ON/OFF
button in normal mode.
• The alarm symbol appears/disappears on the display.
• When the adjusted alarm time is reached, the alarm rings.
• Press any button and the alarm will stop.
• If the alarm is not stopped manually, the ascending alarm tone automatically turns off after two minutes and will be reactivated at the same set
time on the following day.
• The alarm symbol remains on the display.
• When the alarm rings, press the
SNOOZE
button and the snooze function is activated.
• Once the snooze function is activated, the alarm symbol will be flashing on the display.
• There are three different reception states:
Symbol flashing – reception is active
Symbol solid – reception is very good
No symbol – no reception/reception is deactivated/set time manually
• If the clock cannot detect the DCF-signal (e.g. due to interference, transmitting distance, etc.), the time can be set manually. The clock will then
work as a normal quartz clock. (see: Manual settings).
6.2.1 Note on radio-controlled time
The time base for the radio-controlled time is a caesium atomic clock operated by the Physikalisch Technische Bundesanstalt based in Braun-
schweig (Brunswick), Germany. It has a time deviation of less than one second in one million years. The time is coded and transmitted from Main-
flingen near Frankfurt via the frequency signal DCF-77 (77.5 kHz) and has a transmitting range of approximately 1,500 km. The adjustment to Day-
light Saving Time (summer/winter time) is automatic. The reception quality depends mainly on geographic location. Normally there should be no
reception problems within a 1,500 km radius around Frankfurt.
Therefore, please note the following steps:
• The recommended distance to any interfering sources like computer screens or TV sets is at least 1.5 - 2 meters.
• Within concrete walls (reinforced with steel) such as basements, the received signal is naturally weakened. In extreme cases, please place the
unit close to a window to improve reception.
• During night-time, the atmospheric interference is usually less severe and reception is possible in most cases. A single daily reception is ade-
quate to keep the accuracy deviation under 1 second.
7. Operation
• Press and hold the
▼
/ SEC
or
▲

signal no manual adjustment is necessary.
• Press the
▼
/ SEC

▲
/ DM
button if you want to deactivate the DCF reception (OFF).
• Confirm with the
MODE/SET
button.
• Press the
MODE/SET
button to make the settings in the following sequence: Time zone TZ (0 - default), the hours (hour hand is flashing, 12:00 –
00:00 o'clock = PM), the minutes (minute hand is flashing), the year, the month/day sequence (American version) or day/month (European ver-
sion), the month, the day and the day of the week language (GER - default) and the temperature unit (°C - default). Press the
▼
/ SEC
or
▲
/ DM
button to adjust it.
• Confirm with the
MODE/SET
button.
• Once the DCF time signal is successfully received and the DCF reception is activated, the manually set time is overwritten.
