Indoor
temperature
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”
If selected:
•

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.
