Self Programming after Basic Setup or Reset (Putting into Operation)
Features
After the the batteries are inserted (see “Putting into Operation”) into World Time Center and a self programming
sequence will start which cannot be influenced by the user. At first all segments in the LCD will light up for appr. 3
seconds. Next, the unit will perform a battery test followed by the measurements of indoor temperature and humidity,
and a scanning of the WWVB time signals. After this starting phase the indoor temperature (Left on LCD 3) will be
displayed along with the displays “- - -” in the weekday, time (LCD 1), WWVB time (LCD 2) and indoor humidity sections
(Right on LCD 3). If measurements and signal receptions are successful, the dashes will be updated one by one by the
real values measured and received.

Data Reception
Date Setting
Criteria for Reception
1.
The digits for the date will start flashing on LCD 1 (Default setting 1). Set the desired date by use of the “+” key.
Note:
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 date can only be set in conjunction with the selected month. I.e., it is not possible to set the date 30 if the
month of February is selected.
Press the “SET” key to enter the mode “Setting of Year”.
2.
Year Setting
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 year digits will start flashing on LCD 1 (Default setting 1999). Select the desired year by use of the “+” key.
Note:
The year can be selected sequentially from 1998 to 2020 and will then start over again. The year furthermore will
only be visible on the display of LCD 1 in programming mode.
Press the “SET” key to switch to the mode “Worldtime Location Setting”.
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.
3.
2.
3.
Avoid placing the unit onto or in the immediate proximity of metal window frames.
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).
Worldtime Location Setting
1.
The dash representing the first character of the worldtime location (Default setting - - -) on LCD 1 will start flashing.
Select the desired character by use of the “+” key.
2.
3.
4.
5.
Press the “SET” key to move to the second character.
The second dash will start flashing. Select the desired character by use of the “+” key.
Press the “SET” key to switch to the third character.
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.
The third dash will start flashing. Select the desired character by use of the “+” key.
Note:
For designation of the worldtime location the characters “A” through “Z” and “0” as well as “-” and “ ” (Space)
can be chosen.

Subject Index
Care and Maintenance
Here the interested user will find a number of additional informations regarding the function of this Wallclock
Weather Station. Their knowledge however is not necessary for efficient operation of this system.
•
•
Avoid placing the units in places prone to extreme temperatures, vibration and shock as these may cause damage
and inaccurate readings.
When cleaning the World Time Center and Temperature Sensor's displays and casings, use a soft damp cloth
only. Do not use solvents or scouring agents as they may mark the LCDs and casing.
Do not submerge the units in water.
Clock, Radio Controlled
The time base for radio controlled time and date is a operated by the NIST radio station WWVB in Ft. Collins, Colorado.
WWVB broadcasts are used by millions of people throughout the United States to synchronize electronic products like
clocks, clock radios and wristwatches. WWVB continuously broadcasts time and frequenzy signals at 60kHz and the
time information received and displayed is absolutely accurate regardless of summer or wintertime.
•
•
Immediately remove all low powered batteries to avoid leakage and damage. Replace only with new batteries of
the recommended size.
•
Do not make any attempts to repair the units. Return them to their original point of purchase for repair by a
qualified engineer. Opening and tampering with the units may invalidate their guarantee.

•
WWVB Time Signal
Once every day with reception within 12:00am to 6:00am, after every setup or reset and after leaving the
programming mode with the time manually changed the software of the World Time Center will start a reception of
the WWVB time signal.
For best performance, batteries to all units should be replaced when the low battery indicator is displayed on the LCD of
the World Time Center and the Outdoor temperature sensor or at least once a year to maintain maximum running
accuracy.
•
Indoor Temperature and Humidity
The software of the World Time Center will perform measurements of the current indoor temperature every 20
seconds, the current indoor humidity every 1 minute. In programming mode and while any one key is pressed no
WWVB reception will take place.
Please help in the preservation of the environment and return used up batteries only to an
authorized depot.
