1. Pull the battery compartment cover down.

2. Insert the batteries as indicated at the bottom of the battery compartment. Pay

attention to the correct polarity (+/-).

3. Replace the battery compartment cover and push it upwards. The locking tab must

snap audibly into place. Once the batteries are inserted, the clock switches to the receiving mode, see next chapter.Receiving the time signal

CK 2302 DCF radio-controlled clock Notes on changing the battery: Only use the battery type specified in "Technical data". Always change all batteries at the same time. Dispose of old batteries in an environmentally appropriate way (see "Disposal"). Receiving the time signal When you insert the batteries into the radio-controlled clock, all the indicators are displayed for a moment followed by several beeps. The measured room temperature is displayed shortly afterwards. − Press and hold the button for approx. 2 seconds to start radio reception (press to interrupt radio reception again). 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 and the weekday. 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 on 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 "Starting signal reception manually".

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".Receiving the time signal

CK 2302 DCF radio-controlled clock English Setting the time and date manually If there is more than approx. 20 seconds between two pushes of a button, the setting process automatically ends and you will have to repeat it.

1. Press and hold the

button until the indicator for the 12- and 24-hour time format blinks on the display.

or to set the desired time format: "12 H" or "24 H". If you choose "12 H", morning hours will be marked with "AM" and afternoon hours with "PM" on the display.

to save the setting. "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 button or to set the desired value. − Press to save a setting.

5. You should set the following:

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 and hold the button for a few seconds. This is how you manually start (and end, if necessary) the signal 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 clock adjusts itself to the time of the time signal transmitter. If you have already made manual time and date settings, they will be adjusted automatically.About the time signal transmitter DCF77

CK 2302 DCF radio-controlled clock Choosing a location NOTE on material damage Protect the radio-controlled clock from dust, shocks, extreme temperatures, direct sunlight and moisture. Only place the radio-controlled 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 radio-controlled 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 three suspension eyelets on the back and two fold out support feet. − Hang or place the radio-controlled clock as near as possible to a window. The device usually receives the strongest signal there. 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
