BOXX – Radio-controlled alarm clock with thermometer
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 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 approximately 1,500 km. Your radio clock receives the signal, converts it and always shows the exact time. The
adjustment to Daylight Saving Time (summer/winter time) is automatic. In Daylight Saving Time DST is shown on the display.
The reception quality depends mainly on geographic 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.

lowing sequence: minutes, year, month, date and time zone (ZONE 00 - default). Press ▲ or ▼ button to adjust it.
• Confirm the setting with the SET button.
• The manually set time is overwritten once the DCF time signal is successfully received.
8.1.1 Time zone setting
• You can make the time zone correction (+12/-12) in setting mode.
• The time zone correction is needed for countries where the DCF signal can be received but the time zone is different from
the DCF time (e.g. +1=one hour plus).
8.2 12 or 24 hour system
• Press 12/24/▼ button in normal mode to choose 12 HR or 24 HR system. In the 12 HR system AM or PM (after 12
o'clock) appears on the display.
