General Functions (All Modes)
The functions and operations described in this section can be used in all of the
modes.
Auto Return Features
The watch returns to the Timekeeping Mode automatically if you do not perform
any button operation for two or three minutes in the Alarm Mode.
If you leave the watch in a setting mode (with flashing digits) for two or three
minutes without performing any operation, the watch will exit the setting mode
automatically.
Initial Screens
When you enter the World Time or Alarm Mode, the data you were viewing when
you last exited the mode appears first.
Scrolling
The B and D buttons are used in the setting mode to scroll through data. In most
cases, holding down these buttons during a scroll operation scrolls through the
data at high speed.

Configuring Home City Settings
There are two Home City settings: actually selecting the Home City, and selecting
either standard time or daylight saving time (DST).
To configure Home City settings
City code
1. In the Timekeeping Mode, hold down A for about
two seconds until ADJ appears in the right digital dial.
When you release A, the city code and city name will
scroll across the right digital dial. This is the setting
mode.
The watch will exit the setting mode automatically if
you do not perform any operation for about two or
three minutes.
For details about city codes, see the "City Code Table" at the back of this
manual.
Whenever you enter a setting mode, the analog hands will automatically move to
positions that allow easier viewing of the digital dials.
E-26
5. After the setting is the way you want, press A to return to the Timekeeping
Mode.
The DST indicator appears to indicate that Daylight Saving Time is turned on.
Exiting a setting mode will normally cause the hands to return to regular
timekeeping automatically. However, if you manually move the hands (page
E-61) and then enter a setting mode, they will not return to regular timekeeping
automatically when you exit the setting mode. In this case, you will need to
return the hands to their normal positions manually (page E-62).
Note
After you specify a city code, the watch will use UTC* offsets in the World Time
Mode to calculate the current time for other time zones based on the current time
in your Home City.
*
Coordinated Universal Time, the world-wide scientific standard of timekeeping.
The reference point for UTC is Greenwich, England.
