Getting started

• Open the battery compartment and insert two new AAA 1,5 V batteries. Make sure the polarity is correct.
• Close the battery compartment again.
• The device will alert you with a beep and all segments will be displayed for a short moment.
• The clock will now scan the DCF frequency signal and the DCF symbol will be flashing on the display. When the time code is successfully received after 3-7 minutes, the radio-controlled time, the date and the DCF symbol will be shown steadily on the display.
• The DCF reception always takes place daily at 1:00, 2:00 and 3:00 o'clock in the morning. If the reception fails, it will repeat again at 4:00, 5:00 and 6:00 o'clock.
• Press and hold the WAVE button for three seconds and start the initialisation manually. To stop the DCF reception attempt, press the WAVE button again.
• 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).

Radio-controlled time reception
The time base for the radio-controlled time is a caesium atomic clock operated by the Physikalisch Technische Bundesanstalt based in Braunschweig (Brunswick), Germany.
It has a time deviation of less than one second in one million years. The time is coded and transmitted from Mainflingen near Frankfurt via the frequency signal DCF-77 (77.5 kHz) and has a transmitting range of approximately 1,500 km.

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 adequate to keep the accuracy deviation under 1 second.

Operation

Manual settings

• Press the – button in normal mode to change between °C (Celsius) or °F (Fahrenheit) as temperature units.
• Press the SNOOZE/LIGHT sensor button. The backlight turns on for 8 seconds.
• Press and hold the + or – button in setting mode for fast mode.
• The device will automatically quit the setting mode if no button is pressed for 20 seconds.

Setting of the time and date

• Press and hold the TIME button in normal mode for three seconds.
• 24H (default) will be flashing. Press the + or – button to choose 12 Hr or 24 Hr system. In the 12-hour system AM or PM (after 12 o'clock) appears on the display.
• Press the TIME button to make the settings in the following sequence: The time zone (00 - default), the hours, the minutes, the month/day sequence D/M or M/D (D/M - default), the year, the month and the day. Press the + or – button to adjust it.
• Confirm the setting with the TIME button.
• The manually set time is overwritten once the DCF time signal is successfully received.

Alarm time setting

• Press and hold the ALARM button for three seconds to enter the setting mode.
• 6:00 (default) or the last adjusted alarm time appear on the display.
• The hour digits flash.
• Press the + or – button to set the hours.
• Confirm the setting with the ALARM button.
• Set the minutes in the same way.
• To activate the alarm function press the ALARM ON/OFF button.
• The display shows the alarm symbol and 6:00 (default) or the last adjusted alarm time instead of the date.
• When the adjusted alarm time is reached, the alarm rings.
• Press any button (except SNOOZE/LIGHT) and the alarm will stop.
• If the alarm is not stopped manually, the ascending alarm tone automatically turns off after two minutes and it 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/LIGHT button and the snooze function is activated.
• Once the snooze function is activated, the snooze symbol will be flashing on the display.
• The alarm will be interrupted for 5 minutes.
• Press the ALARM ON/OFF button to deactivate the alarm function.
• The alarm symbol disappears and the date appears on the display.
