• The auto receive setting is used for time calibration signal reception only. See "About
Auto Receive" for details.
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 signals transmitted from Rugby and Mainflingen 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 (
A ) whenever you select
or ATH as your Home City code.
• If you experience problems receiving the time calibration signal in your area, it is
probably 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 transmitter indicator starts to
flash, which indicates the setting screen.
2. Press C twice and the DST setting screen appears.
3. Use D to cycle through the DST settings in the sequence shown below.

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

• The hands for the analog timepiece move to adjust to a new setting whenever any of
the following occurs.
When you change the digital time setting manually
When the digital time setting is changed by time calibration signal reception
When you change the Home City code and/or DST setting
• If the analog time does not match the digital time for any reason, use the procedure
described under "To adjust the analog time" to match the analog setting to the digital
setting.
• Whenever you need to adjust both the digital and the analog time settings manually,
make sure you adjust the digital setting first.
• Depending on how much the hands have to move in order to adjust to the digital
time, it may take some time before they stop moving.
