Start-up

For use, you will need two LR6 (AA), 1.5V batteries.

1. Push in a bit the closing flap and remove the lid of the battery compartment.
2. Insert 2 batteries of the type LR6 (AA)/1.5 V as depicted on the bottom of the battery compartment. Pay attention to the correct polarity (+/-).
3. Replace the lid of the battery compartment and fold it down. The closing flap must engage audibly.
   Once the batteries are inserted, the clock switches to the receiving mode, see next chapter.

Notes on changing the battery:

• ‚ Only use the type of battery that is specified in the "Technical Data".
• ‚ Always exchange all of the batteries at the same time.
• ‚ Dispose of batteries in an environmentally appropriate way (see "Disposal").

Receiving the time signal

When the batteries are inserted in the radio-controlled clock, all displays are shown for a brief moment and a beep is heard. The measured room temperature is displayed shortly afterwards.

The device then switches to receiving-mode, during which the number of radio waves indicates the quality of the reception: The more radio waves shown on the display, the better is the reception.
As soon as the signal has been received in sufficient strength, the display also shows

• ‚ the time,
• ‚ the date,
• ‚ the day of the week, and
• ‚ the current moon phase is shown.

The radio-controlled clock automatically switches to receiving mode several times every night. During this process, the displayed time is compared with that received from the time signal transmitter and, if necessary, corrected.
If a sufficiently strong signal has not been received, the radio-controlled clock will cancel the receiving process after a few minutes and the radio tower symbol goes out. The receiving process is started again at a later point in time.
In this case, the time proceeds as usual (beginning with the start time of "00:00").

Checklist when data is missing in the display

No data display from the time signal transmitter

1. Check whether the location of the radio-controlled clock is suitable, see "Choosing a location".
2. Restart reception manually, see "Manually starting signal reception".
3. Wait until the radio-controlled clock automatically switches to receiving mode at a later point in time. The reception is usually better at night.
4. Manually perform the settings if reception is not possible at your location, see "Setting the time and date manually".

Setting the time and date manually

If there is more than approx. 30 seconds between two pushes of a button, the setting process automatically ends and you will have to repeat it.

1. Press and hold the SET button until the indicator for the 12- and 24-hour time format blinks on the display.
2. Using the UP and DOWN buttons, set the desired time format ("12 Hr" or "24 Hr").
3. Press SET in order to save the settings. "00" flashes in the display for the time zone you are in ("00" is the default setting for the European mainland).
4. Proceed as previously described.
   • Press the UP or DOWN button to set the desired value.
   • Press SET each time to save the settings.
5. You should set the following:
   • Hours
   • Minutes
   • Date format
   • Year
   • Month
   • Day
   • Language (relates exclusively to the weekday indicator)
6. Finally, press SET to conclude the procedure.

Starting signal reception of the time signal manually

If the radio signal symbol to the left is no longer displayed, the radio signals from the time signal transmitter are no longer being received. The time indicator nevertheless continues precisely.

• Press the WAVE button. The signal reception is thus started manually.

Pay attention to the following:

• ‚ If the reception was not successful, the reception symbol fades out after a few minutes and the time on the display continues normally.
• ‚ Upon successful signal reception, the radio-controlled clock adjusts itself to the time of the time signal transmitter. If you have already carried out manual time and date settings, these will be automatically adjusted.

Choosing a location

NOTE on material damage

• ‚ Protect the radio-controlled clock from dust, shocks, extreme temperatures, direct sunlight and moisture. Only place the radiocontrolled clock in a dry, closed room.
• ‚ Maintain distance from TV sets, computers, and monitors. Base stations of cordless telephones should also not be in the immediate vicinity of the radio-controlled clock.

• ‚ Depending on your location, it may occur in rare individual cases that the radiocontrolled clock receives signals from another time signal transmitter or even alternately from two time signal transmitters. This is not a fault in the device. In this case, change the location for the radio-controlled clock.
• ‚ The weather, e.g. a heavy storm, can cause interference with the reception.
• ‚ Temporary shutoffs of the transmitter can sometimes happen, e.g. because of maintenance work.

Setting up/hanging the radio-controlled clock
The radio-controlled clock has a hanging loop and a fold-out stand on the back.

• Hang or place the radio-controlled clock as near as possible to a window. Here, the reception will generally be best.

About the time signal transmitter DCF77

This radio-controlled clock receives its radio signals from the time signal transmitter DCF77. This broadcasts the precise and official time of the Federal Republic of Germany on the long-wave frequency of 77.5 kHz.
The transmitter is located in Mainflingen near Frankfurt am Main and, with its range of up to 2000 km, supplies the majority of radio-controlled clocks in western Europe with the necessary radio signals.
As soon as the radio-controlled clock is supplied with power, it switches to receiving mode and searches for the signal from the transmitter DCF77. If the time signal is received in sufficient strength, the display shows the date, time and day of the week.
The radio-controlled clock switches on several times a day and synchronises the time with the radio signal from the transmitter DCF77. In the event the signal is not received, e.g. during a strong storm, the device continues to run precisely and then switches to receiving mode again at the next scheduled time.

Alarm

Setting the alarm time

1. Briefly press the ALARM button once.
   A beep will sound and a bell symbol will appear on the display.
2. Press and hold the ALARM button for a few seconds until "AL" is displayed and the alarm time indication blinks.
3. Using the UP and DOWN buttons, set the desired alarm hour.
   If you press and hold UP or DOWN, the displayed values will be increased or decreased more quickly.
4. Press ALARM.
   The minute indicator for the alarm time blinks on the display.
5. Using the UP and DOWN buttons, set the desired alarm minute.
6. Finally, press ALARM to end the procedure.
