Safety This item can be used by children 8 years of age and above, as well as by persons with reduced physical, sensory, or mental capacities or lacking experience and knowledge, if they are supervised or have been instructed in the safe use of the item and understand the dangers that may arise. Children must not play with the item. Cleaning and user maintenance must not be carried out by children, unless they are 8 years of age or older and are being supervised. Batteries, when swallowed, can be life-threatening. You should therefore keep the item and batteries out of reach of children. If a battery is swallowed, medical assistance must be sought immediately.34 DANGER for children Keep children away from packaging material. Risk of choking if swallowed. RISK of fire/burning and/or explosion Risk of explosion if batteries are improperly exchanged. Replace batteries only with the same or an equivalent battery type. Observe the “Technical Data”. Batteries must not be recharged, reactivated by other means, dismantled, thrown into fire, or short-circuited. Otherwise there is an increased risk of explosion and of leakage; furthermore, gases may escape. Avoid contact of the battery fluid with skin, eyes, and mucosa. In case of contact, rinse the affected areas right away with plenty of clean water and consult a doctor immediately.35

BEWARE of material damage Protect the clock from strong shocks and vibrations. Remove the batteries from the clock when they are exhausted or if you will not use the clock for an extended period of time. You will thus avoid damage that may result from the leakage of battery acid. When inserting and changing batteries, pay attention to the correct polarity (+/-). Do not expose batteries to extreme conditions, for example, by storing them on radiators or under direct sunlight. Increased risk of leakage! Clean the battery and device contacts, as needed, before inserting the battery. Do not make any changes to the item. Only allow repairs to be carried out at a specialist workshop. Repairs carried out incorrectly can considerably endanger the user.

Intended Use This DCF radio-controlled clock is used to display the time and the room temperature. The item is designed for private use and for use in dry areas.37

Overview 1 Symbol for radio reception for time signal transmitter DCF77 2 Time (hours, minutes, seconds) 3 Indoor temperature in °C or °F

SET, , WAVE control buttons 6 Battery compartment, 2x LR03 (AAA)

Start-up For use, you will need two LR03 (AAA), 1.5V batteries.

1. Push the locking tab in the direction of the battery

compartment cover and remove it.

2. Insert the batteries as shown on the bottom of the battery

compartment. Pay attention to the correct polarity (+/-).

3. Replace the battery compartment cover and press it down.

The locking tab must audibly engage. Once the batteries are inserted, the clock switches to the receiving mode, see next chapter. Notes on changing the battery: Only use the battery type specified 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”.40 Receiving the time signal When the batteries are inserted, all displays are shown for a brief moment. 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 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.41

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 clock is suitable, see

“Choosing a location”.

2. Manually restart the receiving process, see “Starting signal

reception manually”.

3. Wait until the 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”.42 Setting the time manually If there is more than approx. 10 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 hour flashes in the

or buttons to set the current hour.

3. Press SET to save the setting.

The minute will flash in the display.

or buttons to set the current minute.

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 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.44 Choosing a location NOTE on material damage Protect the 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 clock. Depending on the location, it may occur in rare individual cases that the 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 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.45

Setting up/hanging the radio-controlled clock The radio-controlled clock has a hanging loop at the back. − Place the radio-controlled clock as close to a window as pos- sible. 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 time is displayed.46 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 clock continues to run precisely and then switches to receiving mode again at the next scheduled time. Other functions Change temperature unit − Press the button to display the temperature in °Celsius or °Fahrenheit. Changing the time display (12-/24-hour) − Press the button to display the time in 12-hour (AM/PM) or 24-hour format. Switching between summer and winter time Switching between summer and winter time, or vice versa, takes place automatically with good time signal reception.47

When daylight saving time is active, the display shows "DST" (Daylight Saving Time). Resetting the radio-controlled clock to factory setting Reset the radio-controlled clock to its factory setting if the display shows unusual or obviously incorrect values.

1. Remove the batteries from the battery compartment and wait

3. Proceed as described in the chapter “Receiving the time

signal”. Cleaning − If necessary, dust the item with a soft, dry cloth or wipe it with a slightly moistened cloth.48 Fault/Remedy DCF77 signal is not received. Check the location. If necessary, start the radio reception manually. Set the time manually. Temperature indication appears too high. Check whether the clock is exposed to direct sunlight. Display is illegible, function is unclear or values are obviously incorrect. Reset the clock to the original factory setting.
