LCD SCREEN AND SETTINGS
For better distinctness, the LCD screen is split into 5 sections displaying the
information for time, date, weather forecast, indoors and outdoors.
LCD 1 RADIO CONTROLLED TIME:
The time base for the radio controlled time is a Cesium Atomic Clock operated by
the Physikalisch Technische Bundesanstalt Braunschweig which has a time
deviation of less than one second in one million years. The time is coded and
transmitted from Mainflingen near Frankfurt via frequency signal DCF-77 (77.5 kHz)
and has a transmitting range of approximately 1,500 km. Your radio-controlled
Weather Station receives this signal and converts it to show the precise time in
summer or wintertime.
The quality of the reception depends greatly on the geographic location. In normal
cases, there should be no reception problems within a 1500km radius of Frankfurt.
Once the outdoor temperature is displayed on the Weather station, the DCF tower
icon in the clock display will start flashing in the upper left corner. 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.
MANUAL TIME SETTING:
In case the Weather station is not able to detect the DCF-signal (disturbances,
transmitting distance, etc.), the time can be manually set. The clock will then work
as a normal Quartz clock. To set the clock:
1.
Press and hold down the SET key for about 3 seconds until the time display
flashes.
2.
Use the IN key to set the hours and the OUT key to set the minutes. Pressing
these keys continuously moves the hours consecutively by 1 and the minutes
consecutively by 5.
3.
Either press the set key once more to enter the set mode for the time zone
and date section or do not touch any buttons for around 30 seconds to
confirm the set time.
Note:
The unit will still try and receive the signal every hour despite it being manually set.
When it does receive the signal, it will change the manually set time into the
received time. During reception attempts the DCF tower icon will flash. If reception
has been unsuccessful, then the DCF tower icon will not appear but reception will
still be attempted the following hour.
LCD 2 TIME ZONE AND DATE SETTING:
The second section of the LCD shows either the month and date, the weekday and
date, Alarm ((1)) time or Alarm ((2)) time. It also shows the Alarm ON/OFF icons
and
