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
