Timekeeping

Use the Timekeeping Mode to set and view the current time and date. You can
also display the Last Signal screen in the Timekeeping Mode.

·

The Last Signal screen alternates between the time and date that the time
calibration signal was successfully received.

Current Time  Setting
Normally, you do not need to do anything to set the current time as long as you
are within an area in West Europe where the watch can pick up the time
calibration signal. You can also set the current time manually when you are
outside the range of the signal.

·

Before using the watch after purchasing it, use the procedure under
“Selecting Your Home City Code” to specify your Home City, and then use the
procedure under “To perform manual time calibration signal reception”.

·

Note that after you set your Home City code, you must also turn on the
watch’s time calibration signal receiver if you want to enable auto time
calibration. See “About Auto Receive” for more information.

·

See “Setting the Digital Time and Date Manually” for information about
manual settings.

·

The analog time of this watch is synchronized with the digital time. Because
of this, the analog time setting is automatically adjusted whenever you
change the digital setting. See “Analog Timekeeping” for more information.

the time and date.

Selecting Your Home City Code

the watch). This data can be changed any time you move to another
geographic area.

See “City Code Table” at the back of this manual for a complete list of
available codes.

·

Once you select a Home City code and set its time, you can use World Time

Time Calibration Signal Reception
This watch is designed to pick up a time calibration signal transmitted from
Mainflingen, Germany and update its time setting in accordance with the
signal. There are two different methods you can use to receive the signal: Auto
Receive
 and Manual Receive. With Auto Receive, the watch automatically
receives the calibration signal twice each day and makes appropriate
adjustments. With Manual Receive, you perform a specific button operation to
receive the calibration signal.

Note

·

If you are using the time calibration signal to set the time for this watch, be
sure to correctly set your Home City. Otherwise, there is the chance that the
watch will not set the correct time. See the “To select your Home City code”
for details.

·

Time calibration reception is limited to specific geographic areas in West
Europe.

·

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.
