TUNE – Radio-controlled alarm clock with radio
• Note: To avoid interference, the backlight (and the USB port) turns off during the reception of the radio controlled
clock.
• When the time code is received after 3-8 minutes, the backlight is activated and the radio-controlled time will be shown.
The DCF symbol remains on the display.
• If the reception fails, the DCF symbol will disappear and the clock will repeat the reception every 3 hours.
• Activate the reception manually by holding the UP button for 3 seconds.
• The backlight will turn off automatically and the DCF symbol will be flashing.
• To end the DCF reception attempt, press the UP button again. The DCF reception symbol disappears.
• The DCF reception always takes place at 2:00 in the morning. If the reception is not successfully received, further
attempts will be taken at 3:00 and 4:00 o'clock.
• If the clock cannot detect the DCF-signal (e.g. due to interference, transmitting distance, etc.), the time can be set manually.
• The clock will then work as a normal quartz clock. (see: Manual settings).
Note on radio-controlled time
The time base for the radio-controlled time is a caesium atomic clock operated by the Physikalisch Technische Bundes-
anstalt 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. The adjustment to Daylight Saving Time (summer/winter time) is automatic.

TUNE – Radio-controlled alarm clock with radio
In Daylight Saving Time DST is shown on the display. The reception quality depends mainly on geographic location. Normal-
ly 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.
