La Crosse Technology WS9132 Instruction Manual page 12

Once the outdoor reception test period is completed, the DCF tower icon in the clock display
will start flashing in the upper center. This indicates that the clock has detected that there is
a radio signal present and is trying to receive it. When the time code is received, the DCF
tower becomes permanently lit and the time will be displayed.
If the tower icon flashes, but does not set the time or the DCF tower does not appear at all,
then please take note of the following:
Recommended distance to any interfering sources like computer monitors or TV sets
•
is a minimum of 1.5 - 2 meters.
Within ferro-concrete rooms (basements, superstructures), the received signal is
•
naturally weakened. In extreme cases, please place the unit close to a window and/ or
point its front or back towards the Frankfurt transmitter.
During nighttime, the atmospheric disturbances are usually less severe and reception
•
is possible in most cases. A single daily reception is adequate to keep the accuracy
deviation below 1 second.
