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 i nto Operat ion)

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, air
pressure 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), W WVB time (LCD 2) and outdoor
temperature/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 the 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 o n the LCD:

• Date (LCD 1) “MON 1.1.98”

• Time of day (LCD 2) “0:00”

If selected:

• Worldtime location (LCD 1) “- - -”

• Worldtime (LCD 1) “0:00”

• Time zone (LCD 2) “0”

Further default values:
Display modes

• Time: 24 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).

• In normal mode display on the right shows the current indoor humidity.

Weather Symbols:

The weather symbols will in the following combinations provide a weather forecast upon reading any sudden changes in
air pressure:

Common to weather forecasting, absolute accur acy cannot be guaranteed. The weather forecasting feature is estimated
to have an accuracy level of about 75% due to the various areas it has been designed to be used in.

Weather Tendency Indicators :

The weather tendency indicator arrows are located to the left and right of the weather symbols. They indicate the air
pressure development and thus, also provide a forecast of the weather to be expected.
The tendency arrows can be displayed as follows:

• Tendency arrow pointing upwards:

• Tendency arrow pointing downwards:

This means that the air pressure is decreasing and the weather is expected to become worse.

Reset of all Data

By removing the batteries from both World Time Cent er and Temperature sensor 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 perf orms 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 dis tance from interferring sources such as TV sets), it
takes between 3 to 5 minutes to receive the signal . If after 10 minutes of inserting th e batteries the WWVB signal is not
properly received then check the following list before manually setting the time (see “Time Sett ing”) in programming
mode.

1. The distance of the units should be at leas t 1.5 - 2.0 Meters away from interferring sources such as computer
monitors or TV sets.

2. Avoid placing the units onto or in the immediat e proximity of metal window frames.

4. Within thick concrete rooms such as basements and tower blocks, the WWVB frequency signal is nat urally

weaker for reception. In extreme cases, place the unit closer to a window and/or point its f ront 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 W WVB
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 ti me 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

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, carefully hang it onto the screw. Always
ensure that the product securely locks on to the screw head before releasing.

Positionning of the Outdoor temperature sensor

The Outdoor temperature sensor has a holder and is supplied screws and double sided tape for affixing by method of
sticking or by screw. Before securing the transmitter to the desired location, check that the temperature can be

received first.

To affix using double sided tape, follow t hese steps:

1.

Peel one side of the tape and press it fir ml y agains t the back of the holder

2.

Now peel the other side of the tape and stic k the holder firmly onto the surface. Do not st ick onto bricks, enamel
finished or greasy surfaces.

Note:

Users are recommended to check that the WWVB time signal or temperatuire from the transmitter 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

To affix by screw, follow these steps:

1. Using the holes in the holder as a guide, mark the holes on the drilling surf ace.

2. Drill the marked area to the required depth

3. Screw the holder onto wall and click the transmitter into holder

• 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.

• Should the World Time Center be moved to another location that is significantly higher or lower than its initial
standing point (e.g. from the ground floor to the upper floors of a house), t hen inaccurate readings may occur. In
such a case either reset the unit s or discard the readings of the weather f orecast for the next 12 to 24 hours. By
doing so, this will allow sufficient time f or operation at a constant altitude, thus enabling a more accurate forecast.

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 cloth
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

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

Every full hour, after every setup or reset and af ter leaving the programming mode the software of the World Time

Center will start a reception of the WWVB time signal.

• Indoor Temperature and Humidity/Air Pressure
The software of the World Time Center will perf orm measurements of the current indoor temperature every 20
seconds, the current indoor hu midity every 1 minute and the current air pressure every 1 minute. I n programming
mode and while any one key is pressed no WWVB reception will take place.

• Battery
After setup, reset or after every outdoor data reception a low-battery detection is started by the software of the

World Time Center. If the batter ies run low, a low battery indication flag is shown on the display.

Weather Symbols

For every sudden or definite change in air pressure, the weather symbols will update accordingly to represent this
change. This means that the icons will not change if there is no noticable movement in the weather . If the symbols do not
change it simply means that either

1) the weather has not changed or

2) the weather change has been so slow that is has not been possible to read when the actual change had tak en
place.

The weather icons displayed forecast the fut ure weather in terms of getting better or worse and not necessarily sunny or
rainy as each icon indicates. E.g., if the current weather is cloudy and the rain icon is displayed, it does not mean that
the product is faulty because it is not raining. It simply means that the air pres sure has dropped and the weather is
expected to get worse but not necessarily raining.

Weather Tendency

Because of the combination of weather icons and weather tendency arrows, the World Time Center can also show how
the weather has changed and is expected to change. E.g., if the tendency arrow pointing downwards is displayed along
with the cloud and sun symbols then the last noticeable change in the weather was when it was sunny (sun icon only).
This means that the next change in weather will show the rainy ic on since the tendency indicator is pointing downwards..

The weather tendency indicator arrow will remain on the LCD regar dless of the weather. E.g., if the cur rent weather is
raining and the indicator is pointing downwards, it means that the weather will remain poor. If the weather is sunny and
the indicator is pointing upwards, it means that the weather is expected to continue being fine.
