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 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.

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.
Auto Return Features
• If you leave the watch in the Alarm (except for the target alarm screen) or Date
Alert Mode for two or three minutes without performing any operation, it
automatically changes to the Timekeeping Mode.
• If you leave a screen with flashing digits on the display for two or three minutes
without performing any operation, the watch automatically exits the setting screen.
Scrolling
The A, B, and D buttons are used in various modes and setting screens to scroll
through data on the display. In most cases, holding down these buttons during a scroll
operation scrolls through the data at high speed.

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 is 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 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.
• The watch is designed to automatically update the date and day of the week for the
period January 1, 2000 to December 31, 2039. Setting of the date by the time
calibration signal cannot be performed starting from January 1, 2040.
• 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 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 ±20 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 transmitter, 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 (
Module 2555
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.
Module 2868
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.
• Since the watch checks signals from both transmitters when
transmitter setting, the signal receive operation can take as long as 14 minutes.
To select a transmitter
1. In the Timekeeping Mode, hold down A until the
transmitter indicator starts to flash, which indicates the
setting screen.
2. Use D to scroll through available transmitter settings
until the one you want to select is displayed.
To set up the watch to do this:
Automatically select the Rugby or Mainflingen signal
Receive the Mainflingen signal
Receive the Rugby signal
