Daylight Saving Time (DST)
Daylight Saving Time (summer time) advances the digital 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 include 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 (
AvtA) whenever you select BER, PAR,
LON, 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 city code starts to flash in the
bottom dial, which indicates the setting screen.
2. Press C once and the DST setting screen will appear in the bottom dial.
3. Use D to cycle through the DST settings in the sequence shown below.
4. When the setting you want is selected, press A to exit the setting screen.
• The DST indicator (
) appears on the bottom dial to indicate that Daylight Saving
Time is turned on.

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.
Note
• 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.
To adjust the analog time
1.In the Timekeeping Mode, press C five times to enter
the Hand Setting Mode.
2.Hold down A until the current digital time starts to flash
in the bottom dial, which indicates the setting screen.
3. Use D and B to adjust the analog setting as
described below.
When you want to do this:
Move the hand setting
forward 20 seconds
Move the hand setting a short
way forward at high speed
Perform this button operation:
• Press D.
• Hold down D.
• Release D when the hands reach the setting
you want.

• To stop the hand movement, press any
button.
• Hand movement stops automatically if the hour
hand makes one full (12-hour) revolution.
4. Press A to exit the setting screen.
• The minute hand will be adjusted slightly to match the seconds when you exit the
setting screen.
• To return to the Timekeeping Mode, press C.
Reference
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.
Power Saving Function
When turned on, the Power Saving function automatically
puts the watch into a sleep state whenever it is left for a
certain period in an area where it is dark. The table below
shows how watch functions are affected by Power Saving.

indicator
• Wearing the watch inside the sleeve of clothing can cause it to enter the sleep state.
• The watch will not enter the sleep state between 6:00 AM and 10:59 PM. If the
watch is already in the sleep state when 6:00 AM arrives, however, it will remain in
the sleep state.
Elapsed Time in Dark
60 to 70 minutes
6 or 7 days
Functions
• LCD off
• Alarm, hourly time signal, analog timekeeping and
auto receive enabled
• LCD off, alarm and hourly time signal disabled
• Analog timekeeping stopped at 12 o’clock
• Auto receive disabled
To recover from the sleep state
Perform any one of the following operations.
• Move the watch to a well-lit area.
• Press any button.
• Angle the watch towards your face for reading.

To turn Power Saving on and off
1.In the Timekeeping Mode, hold down A until the city
code starts to flash in the bottom dial, which indicates
the setting screen.
2.Press C nine times until the Power Saving on/off
screen appears.
3.Press D to toggle Power Saving on (
ON
) and off
(
OFF
).
4.Press A to exit the setting screen.
• The Power Saving indicator (
) remains on the top
dial in all modes while Power Saving is turned on.
Auto Return Features
• If you leave the watch in the Alarm or Hand Setting Mode for two or three minutes
without performing any operation, it automatically returns to the Timekeeping Mode.
• If you leave the watch with a flashing setting in a dial for two or three minutes without
performing any operation, the watch automatically exits the setting screen.
On/Off status
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.
• Even when the watch is within the reception range of the transmitter, signal
reception will be impossible if the signal is blocked by mountains or other geological
formations between the watch and signal source.
• Signal reception is affected by weather, atmospheric conditions, and seasonal
changes.
• The time calibration signal bounces 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 manually.
• The watch is designed to automatically update the date and day of the week for the
period January 1, 2000 to December 31, 2099. Setting of the date by the time
calibration signal cannot be performed starting from January 1, 2100.
• This watch can receive signals that differentiate between leap years and non-leap
years.
• Though this watch is designed to receive both time data (hour, minutes, seconds)
and date data (year, month, day), certain signal conditions can limit reception to time
data only.
• Normally, the signal reception date shown by the last signal screen is the date data
included in the received time calibration signal. When only time data is received,
however, the last signal screen shows the date as kept in the Timekeeping Mode at
the time of signal reception.
• If you are in an area where proper time calibration signal reception is impossible, the
watch keeps time within ±15 seconds a month at normal temperature.
• If you have problems with proper time calibration signal reception or if the time
setting is wrong after signal reception, check your current city code, DST (summer
time), and auto receive settings. The following are the initial factory defaults for these
settings.

Transmitters
This watch is designed to receive the time calibration signal transmitted from Rugby,
England and the signal from Mainflingen, Germany. You can select either one of the
transmitters, or you can configure the watch to automatically select the transmitter that
has the strongest signal.
• The following explains how the watch determines which transmitter it should check
first while the watch is configured for auto transmitter search (
AvtA).
In this case:
The first signal auto search operation
after factory default settings are in effect,
or after the city code has been changed
Any case other than the above.
The watch does this:
1. Checks the Mainflingen signal first.
2. If the Mainflingen signal cannot be
received, checks the Rugby signal.
1. Checks the last successfully received
signal first.
2. If the last successfully received signal
cannot be received, checks the other
signal.
