Important Note:
For all users wanting to get additional informations on the function of the World Time Center there is an
alphabetically sorted subject index at the end of this manual offering a number of technical and funct ional
explanations. For use and operation of this product however the knowledge of this index is not necessary.
Putting into Operation
Basic Setup
Battery
Compartment
1. Open the battery cover of the World Time Center and - checking the correct polarities –
insert 2 x AA, IEC LR6 1.5V batteries into the battery compartment as indicated above and replac e the cover.
2. Your World Time Center is now operational.
Reset
To reset the World Time Center. Wait for at least 30 seconds and repeat the setup procedure above.
Important!
After putting into operation (basic setup or reset) all key functions except for the “SET” and the “+” keys should
not be operated until the WWVB time signal has been received or the time is manually set.
Self Programming after Basic Setup or Reset (Putting into Operation)
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 humidit y,
and a scanning of the WWVB time signals. After this startin g 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.
Initial Displays
If the “SET” key is pressed after “- - -” is displayed (as described in 7.1), but before t he real measurements are
displayed, the learning mode will be terminated. Apart f rom the temperature already displayed on LCD 3 the following
initial displays will now be assigned to the various sections on the LCD:
• Date (LCD 1) “MON 1.1.99”
• Time of day (LCD 2) “12:00”
If selected:
Battery Cover
• Worldtime location (LCD 1) “- - -”
• Worldtime (LCD 1) “12:00”
• Time zone (LCD 2) “EST”
Further default values:
Display modes
• Time: 12 hours
• Temperature: °F (degrees Fahrenheit)
• Language for weekday display: GB (English)
• LCD Contrast: Level 5
Note:
After completion of the self programming procedure check that all frequency signals are correctly received and displayed
in the appropriate sections of the LCD screens. Should any one signal not be received, then see Items “WWVB
Reception Check” below before performing a reset (see Reset abo ve).

Reset of all Data
By removing the batteries from the World Ti me 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 import ant 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 set s), 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 interferr ing 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, pl ace 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 pl acing near metal frames or
structures).
Note:
Users may be located in areas where atmospheric dist urbances are the immediate cause for not r eceiving the WWVB
frequency signal. During nighttime, atmos pher ic disturbances are usually less severe and reception is possible in most
cases. With a single daily recept ion, 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 t ower icon will start flashing in the upper cent er of LCD 2 as a
sign that the signal has been located a nd 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.
Positioning of World Time Center
Hanging
Hole
The World Time Center has been designed to be hung on a wall. To mount please do the following:
1. Fix a screw (not supplied) into the desired wall, leaving the head extended out the wall by about 5 mm as indicated
above.
2. Using the World Time Center's hanging hole on the back of the unit, c arefully hang it onto the screw. Always
ensure that the product securely locks onto the screw head before releasing.
Note:
Users are recommended to check that the WWVB time signal is properly received before permanent
standing, hanging or mounting of World Time Center. Should the World Time Center not pick up the signal
from the desired location, then relocate slightly. Once the signal is received, mount your system units
permanently.
Important Notes
• Avoid placing the World Time Center where it can be exposed to sudden changes in temperature, i.e. direct
sunlight, extreme cold and wet/moist conditions since the design of this product is for indoor use only. This will help
to avoid any inaccurate readings and any possible damage to the unit.
• Should the World Time Center be exposed to extreme and sudden temperature changes, it will lead to rapid
changes in its readings and thereby reduce its ac curacy.
Care and Maintenance
• Avoid placing the units in places prone to extreme tempe ratures, vibration and shock as these may cause damage
and inaccurate readings.
• When cleaning the World Time Center and Temperatur e Sensor's displays and casings, use a soft damp c lot h
only. Do not use solvents or scouring agents as they may mark the LCDs and casing.
• Do not submerge the units in water.
• Immediately remove all low powered batteries to avoid leakage and damag e. 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.
Battery Change
For best performance, batteries to all uni ts 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.
Please help in the preservation of the environment and return used up batteries only to an
authorized depot.

Subject Index
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.
Clock, Radio Controlled
The time base for radio controlled time and d ate is a operated by the NIST radio station W WVB 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 fr equenzy signals at 60kHz and the
time information received and displayed is absolutely accurate regardless of summer or wintertime.
Software Operations
• 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 s tart a reception of
the WWVB time signal.
• Indoor Temperature and Humidity
The software of the World Time Center will perf orm 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.
• Battery
After setup, reset or after every 12:00 am r eception a low-battery detection is starte d by the software of the World
Time Center. If the batteries run low, a low battery indication flag is shown on the dis p lay.
