DCF Radio-controlled alarm clock CK 1940 English As soon as the batteries are inserted, the alarm clock switches to reception, see next chapter. Notes on changing the battery: Only use the battery type specied in the “Technical Data”. Always exchange all of the batteries at the same time. Dispose of old batteries in an environmentally friendly manner, see “Disposal”. Receiving the time signal When the batteries are inserted, all displays are shown for a brief moment and the display is illuminated. 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 time signal has been received in sufficient strength, the time is displayed. The radio- controlled alarm clock automatically switches to reception several times every night. During this process, the displayed time is compared with that received from the time signal transmitter and, if necessary, corrected.34 DCF Radio-controlled alarm clock CK 1940 If a sufficiently strong signal has not been received, the radio-controlled alarm 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

1. Check whether the location of the alarm

clock is suitable, see “Choosing a location”.

2. Manually restart the receiving process, see

“Starting signal reception manually”.

3. Wait until the alarm clock automatically

switches back to receiving mode at a later time.

4. Manually perform settings if reception is

not possible at your location, see “Setting the time manually”.35 DCF Radio-controlled alarm clock CK 1940 English Setting the time manually If there is more than approx. 30seconds between two pushes of a button, the setting process automatically ends and you will have to repeat it.

Starting signal reception 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 1x to start the radio reception. 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 alarm 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.37 DCF Radio-controlled alarm clock CK 1940 English Choosing a location NOTE on material damage Protect the radio-controlled alarm clock from dust, shocks, extreme temperatures, direct sunlight and moisture. Only place it in a dry, closed room. Maintain a distance from TV sets, computers and monitors. Base stations of cordless telephones should also not be in the immediate vicinity of the radio-controlled alarm clock. Depending on the location, it may occur in rare individual cases that the alarm 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 of the alarm clock. The weather, e.g. a heavy storm, can cause interference with the reception. Temporary shutos of the transmitter can sometimes happen, e.g. because of maintenance work.38 DCF Radio-controlled alarm clock CK 1940 Setting up the radio-controlled alarm clock − Set up the radio-controlled alarm clock as close to a window as possible. Here, the reception will generally be best. About the time signal transmitter DCF77 This radio-controlled alarm 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 alarm clock is supplied with power, it switches to reception and searches for the signal from the transmitter DCF77. If the time signal is received in sufficient strength, the time is displayed. The radio-controlled alarm 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 clock continues to run precisely and then switches to receiving mode again at the next scheduled time.39 DCF Radio-controlled alarm clock CK 1940 English Alarm Setting the alarm time
