NEW START AFTER BATTERY CHANGE

The LCD shows "Po 0." You must first move the hands to the exact 
12:00 position with the corrector (left-hand side) and finish with the 
push button (right-hand side), as described in the section "Positioning 
the Hands." Then, if the reception conditions are good, everything else 
takes place automatically, as described in the section "Transmitter 
Call." After your watch has received the transmitter signal for a few 
minutes, it displays the correct time and date. If conditions are bad, or 
your location is outside of the transmitter range, your watch will not be 
able to receive the transmitter signal completely and no time 
information will be displayed. In this case, the software enables you to 
carry out a manual start (next section).

MODE "Po 0" – MANUAL START

After positioning the hands as described in the previous section, press 
the corrector (left-hand side) briefly. The minutes are displayed on the 
LCD. If you continue to press the corrector (left-hand side), the LCD 
minutes and hands will be adjusted (brief press = step-by-step 
adjustment; continuous pressing = high-speed adjustment). In this way, 
you can synchronize your watch with another clock or watch, pressing 
the corrector for the last time on the minute. Finish the manual start by 
briefly pressing the push button (right-hand side). A steady "1" is 
displayed next to the LCD seconds to indicate the manual start. The 
radio tower symbol is not visible. In manual start mode your watch 
attempts to receive the transmitter signal every hour. A transmitter call 
is also possible, but should only be carried out when you are within the 
transmitter range. After successful reception, your watch automatically 
displays the radio-controlled time (radio tower symbol is visible).
