Getting started

• Open the battery compartment and insert the two batteries 1,5 V AA. Make sure the polarities are correct.
• Close the battery compartment again.
• The device will alert you with a beep and all LCD 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 LCD. When the time code is received successfully after 3-8 minutes, the radio-controlled time, the date and the DCF symbol are displayed steadily in the LCD.
• The DCF reception always takes place at 3:00 o'clock in the morning. If the reception is not successfully received at 3:00 o'clock, it shall be held further attempts at 4:00 and 5:00 o'clock.
• If there is no reception possible, manual initialization can be helpful.
• Press and hold the – button for three seconds.

• The DCF symbol will be flashing.
• To end the reception, press and hold the– button for three seconds again. The DCF symbol disappears.
• There are three different reception symbols:

  flashes	reception is active
  stays	reception is good
  no symbol	reception is deactivated/turned off

• If the clock cannot detect the DCF-signal (for example due to disturbances, 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 Braunschweig. 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 frequency signal DCF-77 (77.5 kHz) and has a transmitting range of approximately 1,500 km. Changeover from summer time or winter time is automatic. In Daylight Saving Time is shown on the LCD. The quality of the reception depends mainly on the geographic location. Normally there should be no reception problems within a 1,500 km radius around Frankfurt.

Please take note of the following:

• The recommended distance to any interfering sources like computer monitors or TV sets is at least 1.5 - 2 meters.
• Inside ferro-concrete rooms (basements, superstructures), the received signal is naturally weakened. In extreme cases, please place the unit close to a window to improve the reception.
• During nighttime, 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

• Press and hold– or + button in the setting mode for fast running.
• The instrument will automatically quit the setting mode if no button is pressed within 15 seconds.
• If the button tone is enabled, each button operation is acknowledged with a beep.

Manual settings

• Press and holdSET button at the back in normal mode for three seconds.
• dcF appears on the display and ON (default) will be flashing. If the DCF reception is activated and after successful reception of the DCF signal no manual adjustment is necessary.
• Press the– or + button if you want to deactivate the DCF reception (OFF).
• Confirm the setting with the SET button.
• If the DCF reception is enabled (ON), you can set the time zone after confirmation with the SET button (TZ appears on the display and 0 default will be flashing).

• Press the– or + button to adjust the time zone (-9/+9).
• The time zone setting 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 later).
• Confirm the setting with theSET button.
• Press theSET button to make the settings in the following sequence: the hours, the minutes, the year, the month, the day, the temperature unit (default °C), the day-of-week language (default German), and the button tone (default OFF). Press the – or + button to adjust it.
• Confirm the setting with theSET button.
• By a successful reception of the DCF reception signal and if the DCF reception is activated (ON), the manually set time will be overwritten.

Setting of the temperature unit

• Press the– or + button to toggle between Celsius (°C) or Fahrenheit (°F) as temperature unit select.
• Confirm the setting with theSET button.

Setting of the day-of-week language

• Adjust the desired day-of-week language with the– or + button: German (D), English (EN), French (FR), Spanish (ES), Italian (IT) or Dutch (NL).
