Current Time Setting
This watch automatically adjusts its time setting in accordance with a time calibration
signal. You can also perform a manual procedure to set the time and date, when
necessary.
• 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
Rugby 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.

the middle of the night). You can also perform manual receive or you can set the time

If the Power Saving indicator ( ) is flashing on the display,
PS
it means that the display is blank because the watch's
Power Saving function has turned it off to conserve power.
Power Saving automatically turns off the display and
enters a sleep state whenever your watch is left for a
certain period in an area where it is dark. If the watch is
kept in the dark for a longer period, the analog hands will
also stop moving after a few days.
• The initial factory default setting is Power Saving on.
• The watch will recover from the sleep state if you move it
to a well-lit area or if you press any button.
• See "Power Saving Function" for more information.
