Leaving the Programming Mode
•To return to the normal display mode from anywhere in programming mode simply press any desired key but the “SET” or the “+” key at any time.
•If no keys are pressed for at least 15 seconds in programming mode, the Wallclock Weather Station will automatically switch back to normal display mode.
Reset of all Data
By removing the batteries from the World Time Center all displayed data will be lost. To reset all data perform a basic setup as described in “Reset” above.
Data Reception
Criteria for Reception
For reception and computing of displayed values, the software of the World Time Center performs a number of comprehensive operations (see Index) which are not necessarily important for the user to know. In case the time is not correctly displayed on LCD 2, then please see “ WWVB Reception Check”.
WWVB-Signal Test
The World Time Center will automatically start scanning for the WWVB frequency signal (time signal transmission) after the batteries are inserted. In normal surroundings (i.e. at a safe distance from interferring sources such as TV sets), it takes between 6 to 10 minutes to receive the signal. If after 10 minutes of inserting the batteries the WWVB signal is not properly received then check the following list before manually setting the time (see “Time Setting”) in programming mode.
1.The distance of the units should be at least 1.5 - 2.0 Meters away from interferring sources such as computer monitors or TV sets.
2.Avoid placing the unit onto or in the immediate proximity of metal window frames.
3.Within thick concrete rooms such as basements and tower blocks, the WWVB frequency signal is naturally weaker for reception. In extreme cases, place the unit closer to a window and/or point its front or rear towards the general direction of NIST Radio Station WWVB in Ft. Collins, Colorado (again avoid placing near metal frames or structures).
Note:
Users may be located in areas where atmospheric disturbances are the immediate cause for not receiving the WWVB 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 World time Center to keep time accuracy deviation to below 0.5 seconds in a period of 24 hours.
When reception is successful, the WWVB transmission tower icon will start flashing in the upper center of LCD 2 as a sign that the signal has been located and is about to be received. Once the signal has been locked, the WWVB tower icon will stay fixed on the LCD and the received time will then update and correct the manually set time.
