BIMBAM - Radio-controlled clock with hourly chime
• Low batteries should be changed as soon as possible to prevent damage caused by leaking. Never use a combination of old and new batter-
ies together, nor batteries of different types.
• Wear chemical-resistant protective gloves and safety glasses when handling leaking batteries.
Important information on product safety!
• Do not expose your device to extreme temperatures, vibrations or shocks.
• Protect it from moisture.

6. Getting started
• Remove the protective film from the display.
• Open the battery compartment and insert four new AA 1.5 V batteries, polarity as illustrated.
• Close the battery compartment again.
• The default chime will sound and all segments will be displayed for a short moment.
6.1 Radio-controlled time reception
• The clock will now scan the DCF frequency signal and the DCF symbol will be flashing on the display. When the time code is successfully
received after 3-10 minutes, the radio-controlled time and the DCF symbol will be shown steadily on the display.
• You can also start the initialization manually.
• Press and hold the ON OFF / +button for 3 seconds.
• The DCF reception symbol will be flashing.

BIMBAM - Radio-controlled clock with hourly chime
• If you want to interrupt the reception, press the ON OFF / + button again for three seconds. The DCF reception symbol disappears.
• The DCF reception always takes place daily at 2:00, 3:00, 4:00 and 5:00 o'clock in the morning. If the reception is not successfully received
until 5:00 o'clock, the next DCF reception attempt will happen at 2:00 o'clock in the following morning.
• There are three different reception states:
flashing symbol – reception is active
solid symbol – reception is very good
no symbol – no DCF reception
• If the clock cannot detect the DCF-signal (e.g. due to interference, transmitting distance, etc.), the time can be set manually. The DCF recep-
tion symbol disappears and the clock will then work as a normal quartz clock (see: Manual settings).
6.1.1 Note on radio-controlled time
The time base for the radio-controlled time is a caesium atomic clock operated by the Physikalisch Technische Bundesanstalt based in Braun-
schweig (Brunswick), Germany. It has a time deviation of less than one second in one million years. The time is coded and transmitted from
Mainflingen near Frankfurt via the frequency signal DCF-77 (77.5 kHz) and has a transmitting range of approximately 1,500 km. The adjustment
to Daylight Saving Time (summer/winter time) is automatic. The reception quality depends mainly on geographic location. Normally there
should be no reception problems within a 1,500 km radius around Frankfurt.
Please note the following guidelines:
• The recommended distance to any interfering sources like computer screens or TV sets is at least 1.5 - 2 meters.
• Within concrete walls (reinforced with steel) such as basements, the received signal is naturally weakened. In extreme cases, please place
the unit close to a window to improve reception.
• During night-time, the atmospheric interference is usually less severe and reception is possible in most cases. A single daily reception is
adequate to keep the accuracy deviation under 1 second.
7. Operation
• Important: The device cannot be operated during the DCF time-signal reception.
• During the operation, all successful settings will be confirmed by a brief beep tone.
• Press and hold the ON OFF / + button or SET / - button in the respective setting mode for fast setting.
• The device will automatically quit the setting mode if no button is pressed for a long period of time.
7.1 Manual settings
• Press and hold the SET button in normal mode for three seconds.
• The time zone Z (0 - default) will be flashing. Press the ON OFF / + button or SET / - button to make the time zone correction (+9/-9).
