CHECKING FOR DCF-77 RECEPTION:
The Remote Thermo will automatically start scanning for the DCF-77 frequency signal after the
battery is inserted. In normal surroundings (for example away from interfering sources such as TV
sets), it takes between 3-5 minutes to receive the signal. If after 10 minutes after having inserted the
batteries into the alarm clock and the DCF-77 signal is not received, then check the following list
before manually setting the time (see Manual time setting):

Note:
Users may be located in areas where atmospheric disturbances are the direct cause for not
receiving the DCF-77 frequency signal. During nighttime, atmospheric disturbances are usually less
severe and reception is possible in most cases. With a single daily reception, it is adequate for the
alarm clock to keep time deviation to below 0.5 seconds in a period of 24 hours.
The distance of the Remote Thermo should be at least 1.5-2.0 meters away from interfering
sources such as computer monitors or TV sets.
Avoid placing the alarm clock onto or in the immediate proximity of metal, doors, windows
frames or structures.
Within thick concrete rooms such as basements and tower blocks, the DCF-77 signal is
naturally weaker. In extreme cases, place the alarm clock closer to a window and/or point its
front or rear towards the general direction of the Frankfurt/Main transmitter (avoid positioning
within close proximity of metal frames or structures).
