Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the time setting by one hour from
Standard Time. Remember that not all countries or even local areas use Daylight
Saving Time.
The time calibration signal transmitted from Mainflingen and Rugby includes both
Standard Time and DST data. When the Auto DST setting is turned on, the watch
switches between Standard Time and DST (summer time) automatically in
accordance with the received time signal.
• The default DST setting is Auto DST (
) whenever you select LIS, LON, BCN,
MAD, PAR, MIL, ROM, BER, STO, or ATH as your Home City code.
• If you experience problems receiving the time calibration signal in your area, it
probably is best to switch between Standard Time and Daylight Saving Time
(summer time) manually.
To change the Daylight Saving Time (summer time) setting
1. In the Timekeeping Mode, hold down A until the city code starts to flash, which
indicates the setting screen.
2. Press C and the DST setting screen appears.
3. Use D to cycle through the DST settings in the sequence shown below.
Auto DST ( ) DST off ( ) DST on ( )
4. When the setting you want is selected, press A to exit the setting screen.
• The DST indicator appears to indicate that Daylight Saving Time is turned on.

This section contains more detailed and technical information about watch operation.
It also contains important precautions and notes about the various features and
functions of this watch.
Button Operation Tone
The button operation tone sounds any time you press one
of the watch’s buttons. You can turn the button operation
tone on or off as desired.

In any mode (except when a setting screen is on the
display), hold down C to toggle the button operation tone
on (MUTE not displayed) and off (MUTE displayed).

• Since the C button is also the mode change button, holding it down to turn the
button operation tone on or off also causes the watch’s current mode to change.
• The MUTE indicator is displayed in all modes when the button operation tone is
turned off.
Power Saving Function
When turned on, the Power Saving function enters a sleep
state automatically whenever the watch is left in an area
where it is dark for a certain period. The table below
shows how watch functions are affected by the Power
Saving function.

Scrolling
The B and D buttons are used in various modes and setting screens to scroll
through data. In most cases, holding down these buttons during a scroll operation
scrolls through the data at high speed.
Initial Screens
When you enter the World Time or Alarm Mode, the data you were viewing when you
last exited the mode appears first.
Radio-controlled Timekeeping Precautions
• Strong electrostatic charge can result in the wrong time being set.
• The time calibration signal is bounced off the ionosphere. Because of this, such
factors as changes in the reflectivity of the ionosphere, as well as movement of the
ionosphere to higher altitudes due to seasonal atmospheric changes or the time of
day may change the reception range of the signal and make reception temporarily
impossible.
• Even if the time calibration signal is received properly, certain conditions can cause
the time setting to be off by up to one second.
• The current time setting in accordance with the time calibration signal takes priority
over any time settings you make.
