When you are not wearing the watch on your wrist,

 

 

 

 

 

 

 

 

 

 

 

position the face so it is pointed at a source of bright

 

 

 

 

 

 

 

 

 

 

 

light.

 

 

 

 

 

 

 

 

 

 

 

You should try to keep the watch outside of your sleeve

 

 

 

 

 

 

 

 

 

 

 

as much as possible. Charging is reduced significantly if

 

 

 

 

 

 

 

 

 

 

 

the face is only partially covered.

The watch continues to operate, even when it is not exposed to light. Leaving the watch in the dark can cause the battery to run down, which will result in some watch functions to be disabled. If the battery goes dead, you will have to re-configure watch settings after recharging. To ensure normal watch operation, be sure to keep it exposed to light as much as possible.

The second hand will move at high speed to the 12 o’clock position, where it will stop.

2.Use D(east) and B(west) to select the city code you want to use as your Home City.

The following are the city codes for major cities in the Western Europe time zones.

LON: London

PAR and BER: Paris, Berlin, Milan, Rome, Amsterdam, Hamburg, Frankfurt, Vienna

ATH: Athens

3. Press A to exit the setting screen.

The second hand will advance at high speed to the correct position in accordance with seconds count of the digital time, and resume normal movement from there.

The first thing you should do after purchasing this watch is to set your Home City, which is the city where you will normally use the watch. For more information, see “To set your Home City” below.

When using the watch in an area that is outside of the range of the transmitters in Anthorn and Mainflingen, you need to manually adjust the time as required. See “Timekeeping” for information about manual settings.

The analog time of this watch is synchronized with the digital time. Because of this, the analog time setting is automatically adjusted whenever you change the digital

setting. See “Analog Timekeeping” for more information.

Normally, your watch should show the correct time as soon as you select your Home City code. If it does not, it should adjust automatically after the next auto receive (in the middle of the night).You can also perform manual receive or you can set the time manually.

If you are in an area that does not use Daylight Saving Time (summer time), turn off the DST setting.

The watch will receive the time calibration signal automatically from the applicable transmitter (in the middle of the night) and update its settings accordingly. For information about the relationship between city codes and transmitters, see “Transmitters”.
