BOOM – High performance radio-controlled alarm clock with vibration alarm
6.2 Radio-controlled time reception
The time base for the radio-controlled time is a caesium atomic clock operated by the Physikalisch
Technische Bundesanstalt based in Braunschweig (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 approxi-
mately 1,500 km. The adjustment to Daylight Saving Time (summer/winter time) is automatic. In
Daylight Saving Time is shown on the display. The reception quality depends mainly on geo-
graphic location. Normally there should be no reception problems within a 1,500 km radius
around Frankfurt.
Therefore, please note the following steps:
• 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.
6.3 Insert the batteries
• The batteries will operate as a backup power source in case of power failure.
• For a permanent backlight, to use the vibration alarm and to conserve battery power, use the
supplied power adapter.
• Open the battery compartment at the bottom of the device.
• Insert two new AA 1,5 V batteries into the battery compartment. Make sure the polarity is cor-
rect.
• Close the battery compartment again.
7. Operation
• Press and hold the – or + button in setting mode for fast mode.
• The device will automatically quit the setting mode if no button is pressed for 15 seconds.
7.1 Manual settings
• Press and hold the SET button at the back in normal mode for three seconds.
• dcF appears on the display and ON (default) will be flashing. By default, the DCF reception is
activated and after successful reception of the DCF signal no manual time setting is necessary.
• Press the – or + button if you want to deactivate the DCF reception (OFF).
• Once the DCF time reception is deactivated the clock and date must be manually set. Then the
DCF reception symbol disappears. No time zone will appear.
• Confirm the setting with the SET button.
• Press the SET button again to do the settings in the following sequence: The 12 or 24 hours
system (24hr - default), the time zone (0 - default), the hours, the minutes, the year, the month
and the day, the day-of-the-week language (GERMAN - default), the button tone bEEP (OFF -
default) and the Auto Light brightness level (LOW - default). Press the – or + button to adjust it.
• Confirm the setting with the SET button.
• Once the DCF time signal is successfully received and the DCF reception is activated (dcF ON),
the manually set time is overwritten.
