To reset the World Time Center and the Outdoor temperature sensor, simply take out the batteries from both unit. 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 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).
LCD Screens

The LCD of your World Time Center consists of t h r ee separate screens which provide - from top to bott om - the following
information:

LCD 1 - Worldtime and Date/Weekday

City

• In normal mode display of current date (Day and Month. Year will only show in programming mode) with current
weekday (abbreviated to 3 letters; 8 languages to c hoose from).

• By key stroke display of radio controlled, highly accurate worldtime at any location on earth (identified by 3 letter
abbreviation).

• By key stroke alternating display of both above modes every 5 seconds.

LCD 2 - Time of Day

World
Time

• In normal mode display of radio controlled, highly accurate time of day depending on programming - 12 or 24 hours
mode.

• A transmission tower symbol in the upper center of the di splay indicates that the WWVB time signal is scanned for
(flashing) or received (steady).

• A battery symbol in the lower center indicates low running batt eries.

LCD 3 - Temperature/Indoor Humiditiy and Weather Forecast

Indoor

• On the left, display of current indoor temperature.

• On the right, display of current outdoor t emperature and by pressing the “ Hygro ” key, alternate between

• In the center, the display shows the expected weather in the f orm of three weather symbols and weather tendency

• 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.
