DANGER for children Keep children away from packaging material. There is a risk of choking if swallowed. RISK of fire/burning and/or explosion There is a risk of explosion if the batteries are replaced improperly. Replace the 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 leakage; furthermore, gases may escape!44 Avoid contact of the battery fluid with skin, eyes, and mucosa. In case of contact, immediately rinse the affected areas with plenty of clean water and consult a doctor. BEWARE of material damage Protect the alarm clock from strong shocks, vibrations, and moisture. Remove the batteries from the item when they are exhausted or if you will not use the alarm clock for an extended period of time. This prevents damage that may be caused by leakage. When inserting and changing batteries, pay attention to the correct polarity (+/-). Do not expose the batteries to extreme conditions, for example, by storing them on radiators or under direct sunlight. Increased risk of leakage!45

Clean the battery and device contacts, as needed, before inserting the battery. Only use batteries of the same type. Do not use different types or used and new batteries together. Do not make any changes to the product. Only allow repairs to be carried out by a specialist workshop. Repairs carried out improperly can considerably endanger the user. Intended use This radio-controlled alarm clock receives its time signal from the German time signal transmitter DCF77. The alarm clock is designed exclusively for private use in dry indoor areas.46 Overview

1. Remove the battery compartment cover

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 cover must audibly engage. 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 specified in the “Technical Data”. Always replace all batteries. Dispose of old batteries in an environmentally friendly manner, see “Disposal”.53

Receiving the time signal When the batteries are inserted, all displays are shown for a brief moment and a beep is heard. The measured room temperature and the humidity are 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. No manual entry with the buttons is available during radio signal reception. As soon as the time signal has been received in sufficient strength, the display also shows the time, the day of the week, and the date.54 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. 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 on the display

1. Check whether the location of the radio-

controlled alarm clock is suitable, see “Choosing a location”.55

2. Manually restart the receiving process, see

“Starting signal reception manually”.

3. Wait until the alarm clock automatically

switches back to reception at a later time.

4. Manually perform settings if reception is

not possible at the location, see “Setting the time and date manually”. 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 display continues to run precisely. − Press and hold the WAVE button until radio reception is started.56 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 made manual time and date settings, they will be adjusted automatically. 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 flashes in the display.57

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 described:

− Press the + or – button to set the desired value. − Press each time to save a setting.

5. Perform the following settings one after the

to exit. Choosing a location NOTE on material damage Protect the alarm clock from dust, shocks, extreme temperatures, direct sunlight and moisture and 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 your location, it may occur in rare individual cases that the alarm clock receives signals from another time signal59

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 shutoffs of the transmitter can sometimes happen, e.g. because of maintenance work. 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.60 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 display shows the date and time. 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 device continues to run precisely and then switches to receiving mode again at the next scheduled time.61

Alarm You can set two different alarm times with the alarm clock, for example, one for the week and one for the weekend. Both alarm functions are set and operated in the same way. Setting the alarm time

1. Press and hold the button until the alarm

hour flashes in the display under the symbol (= alarm time 1). To set alarm time 2, press repeatedly until the alarm hour flashes under the symbol (= alarm time 2).

2. Use + or – to set the alarm hour.

If you press and hold + or –, the displayed values will be increased or decreased more quickly.62

The minute indicator for the alarm time blinks on the display.

4. Use the + or – buttons to set the desired

key. The hour indicator for alarm time 2 ( ) flashes in the display.

6. Proceed as described to set a second alarm

time or press repeatedly until the display shows the date, temperature and humidity again.

switch to ON to activate alarm time 1. is shown on the display. Waking up At the set time, you will be woken by an alarm signal, which will become more intense as the waking time increases.63

Interrupting the alarm for 24 hours − Press any button (except ) to interrupt the alarm. After 24 hours, the alarm will be triggered again. Auto-stop function If you do not press a button, the alarm switches off automatically after 2 minutes. After 24 hours, the alarm will be triggered again. Repeat alarm (snooze function) − Press the button 1x when the alarm sounds. The alarm signal becomes silent and flashes in the display (at alarm time 1). After 5 minutes, the device switches on again and wakes you up again. This procedure can be repeated multiple times.64 Switching the alarm function off and on − Sliding the / switch to OFF switches off the respective alarm function (1 or 2). and/or disappear on the display. Other functions Illuminating the display − Pressing the button turns on the display backlight for approx. 8 seconds. − When the AUTOLIGHT switch is set to ON, the display light turns on automatically at the onset of darkness. However, the battery consumption is higher (OFF = AUTOLIGHT function disabled). Change temperature unit − Press the – button to display the temperature in °Celsius or °Fahrenheit.65

Switching between summer and winter time Switching between summer and winter time, or vice versa, takes place automatically with good time signal reception. When daylight saving time is active, the display shows “DST” (Daylight Saving Time). Resetting the radio-controlled alarm clock to defaults Reset the radio-controlled alarm clock to its factory setting if the display shows unusual or obviously incorrect values.

1. Remove the batteries from the battery

compartment and wait a moment.

2. Reinsert the batteries. Observe the correct

polarity of the batteries (+/-).

3. Proceed as described in the chapter

“Receiving the time signal”.66 Cleaning − If necessary, dust the item with a soft, dry cloth or wipe it with a slightly moistened cloth. Fault/Remedy DCF77 signal is not received. Check the selected location. If necessary, start the radio reception manually. Set the time manually. Temperature indication appears too high. Check whether the alarm clock is exposed to direct sunlight. The indicator is illegible, the function is unclear, or the values are obviously false. Reset the alarm clock to the original factory setting.67

The time differs by exactly one, two, three, etc. hours. The wrong time zone was probably set.
