The Radio Controlled Clock
With the Radio-Controlled Clock, you can have the most accurate time within the continent. It can
receive the time signal transmitted by Physikalisch-Technische Bundesanstalt (PTB) of Germany,
which is regulated by 4 atomic clocks. PTB transmits the time signal (DCF77, 77.5kHz)
continuously from Mainflingen, 25 km southeast of Frankfurt am Main. It is expected that the
signal can cover a distance of approx. 1,500km from the transmitter. However, some
environmental effects affect the transmitting distance.

Environmental Reception Effects
The Radio-Controlled Clock obtains the accurate time with wireless technology. Same as all
wireless devices, the receiving ability may be affected by, but not limited to, the following
conditions (see also the "Local Precautions")
• Long transmitting distance.
• Nearby mountains and valleys.
• Among tall buildings.
• Near railway, high voltage cable, etc.
• Near freeway, airport, etc.
• Near construction site.
• Bad weather.
• Nearby metallic structures.
