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 equivalent battery type. Refer to “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!
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.

BEWARE of material damage

Protect the alarm 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 leakage of battery acid.
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!
Clean the battery and device contacts, as needed, before inserting the battery.
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.

Start-up

The alarm clock is powered by two 1.5 V R03 (AAA) batteries.

Push the battery compartment cover upwards and remove the cover.
Insert the batteries as shown on the bottom of the battery compartment. Pay attention to the correct polarity (+/-).
Replace the battery compartment cover and push it down until it is secure. 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, as described in “Disposal”.

Receiving the time signal

With the batteries in place, you will hear several beeps, and all indications will appear briefly on the backlit display.
After a short time, the display shows the measured room temperature and indoor air humidity.

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.

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 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”

Setting the time manually

two button presses, the setting process is terminated automatically, and you have to start over.
Each push of a button is confirmed with a beep.

Keep the button pressed until BEEP ON appears on the display.
Use the button or to select ON or OFF (OFF = you will no longer hear a beep when you press the button).
Press to save the setting.
The display shows TIME ZONE, and “00” flashes, where “00” means your current time zone.
Use button or to select the time zone of your current location (“00” is the default setting for mainland Europe).
Proceed as described:
− Press the button or to set the desired value.
− Press each time to save the setting.
Perform the following settings one after the other:
Hour (HOUR)
− Minute (MINUTE)
− Year (YEAR)
− Month (MONTH)
− Day (DATE)
− Language (LANGUAGE, applies only to the weekday display)
Finally, press to exit.

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 button once and hold it to start 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 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.

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 shutoffs of the transmitter can sometimes happen, e.g. because of maintenance work.

Setting up the radio-controlled alarm clock

− Place the radio-controlled clock as close to the window as possible. The device usually receives the strongest signal there.

About the time signal transmitter DCF77

The radio-controlled clock receives radio signals from the DCF77 time signal transmitter. 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.
When you power up the clock, it switches to Reception mode and searches for the signal from the DCF77 transmitter. If the time signal is received in sufficient strength, the time is displayed.
The clock switches on multiple times daily and synchronises the clock time with the radio signal from the DCF77 transmitter. 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.

Alarm

The device offers the possibility of setting two alarm times independently of each other.
For each alarm time you can specify the days on which it should be active:

Monday to Friday (“M-F” display),
Saturday to Sunday (“S-S” display) or
Monday to Sunday (“M-S” display)

Both alarm times are set in the same way.

Setting the alarm time

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.
The indication of the displayed values changes faster by holding the button or .
