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. 

• 

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 display indicates that the WWVB time signal is scanned for 
(flashing) or received (steady). 

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. 

• 

A battery symbol in the lower center indicates low running batteries.

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), WWVB 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 from 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 1.1.98”

  

• 

Time of day (LCD 2) 

“0:00”

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

 above). 

 

LCD Screens 
 

The LCD of your World Time Center consists of three separate screens which provide - from top to bottom - the following 
information: 
 

LCD 1  -  Worldtime and Date/Weekday 
 
 

 

 

 

 
 
 
 

• 

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 choose 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 

 

 
 
 
 

• 

On the left, display of current indoor temperature. 

Indoor relative 
humidity 

• 

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

1. 

the indoor relative humidity,  

2. 

indoor relative humidity and outdoor temperature, and  

3. 

outdoor temperature  

• 

In the center, the display shows the expected weather in the form of three weather symbols and weather tendency 
indicator in the form of an arrow. 

• 

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: 
 
 
 
 
 
 
 

Sunny 

 

    Cloudy with sunny intervals   

Rainy

 

 

 

Common to weather forecasting, absolute accuracy 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:

  

This means that the air pressure is increasing and the weather is expected to improve. 

 

• 

Tendency arrow pointing downwards: 

 

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