• The date can be set within the range of January 1, 1995 to December 31, 2039.
• When you use the above procedure to set the time on the digital display, the hands of
the analog timepiece normally adjust according to your setting. If, for any reason, the
analog time does not match the digital time, use the procedure described under Hand
Setting Mode to match the analog setting with the digital display.
About daylight saving time
With daylight saving time (summer time), clocks are set one hour later in order to better
take advantage of daylight hours during the summer, when days are longer. Whether or
not daylight saving time is used depends on the country you are in.

HAND SETTING MODE
Use this mode to make corrections when the time shown
on the digital display does not match the time indicated
by the analog hands.
Important:
Before performing the time calibration operation, be
sure to synchronize the digital time with the analog
time using the procedures described below. If not, the
setting of the hands could result in being different from
the digital time which is changed by the calibration
signal.

TIME CALIBRATION SIGNAL
This watch is designed to receive the time calibration signal transmitted from Frankfurt,
Germany. It automatically adjusts its current time setting in accordance with the signal it
receives. There are two different methods you can use for signal receipt. With auto
receive, the watch automatically receives the calibration signal twice each day and
makes appropriate adjustments. You can also use manual receive, where you perform
a specific button operation to receive the calibration signal.
• The current time setting in accordance with the 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, 1995 to December 31, 2039. Setting of the date by the calibration
signal cannot be performed starting from January 1. 2040.
• This watch can receive signals that differentiate between leap years and non-leap years.
How the analog hands react on the time calibration
After the watch successfully receives time calibration signal data, it automatically changes
the settings of its hands. Before performing the time calibration operation, be sure to
synchronize the digital time with the analog time using the procedures described under
“Hand Setting Mode”. If not, the setting of the hands could result in being different from
the digital time which is changed by the calibration signal.
Auto receive
When auto receive is switched on, the watch automatically receives the calibration signal
starting from when the digital time reaches 2:00 AM and 4:00 AM each day. Calibration
is performed regardless of what mode the watch is in, except when you are performing a
data input or time setting operation (indicated by the flashing display). Use the following
procedure to switch auto receive on and off.
To switch auto receive on and off
1. In the Timekeeping Mode, hold down
A
until the “On” or “OFF” message appears on
the display.
2. Press
C
to switch auto receive on and off.
Press

Receive indicator
Flashes when calibration signal is being received.
3. Press
A
to return to the Timekeeping display.
• Auto receipt of the calibration signal is designed to be performed early in the morning,
while you sleep (provided that the digital time is set correctly). Before going to bed for
the night, remove the watch from your wrist, and put it in a location where it can easily
receive the signal. You should also orient the watch properly for best reception. See
“Tips for ensuring best reception” for details.
• Auto receive is switched on when the watch is shipped from the factory.
• The receive indicator appears on the display when the calibration signal is received
successfully. It disappears from the display when the watch is unable to receive the
signal for some reason. You can tell whether the last time the watch tried to receive
the calibration signal was successful or not by checking the receive indicator.
How the auto receive time calibration is performed
• When auto receive is switched on, the watch receives the calibration signal for two to
six minutes each day when the digital time reaches 2:00 AM and 4:00 AM (calibration
times). Make sure you do not try to operate any of the watch’s buttons while the
calibration signal is being received. Doing so can interfere with correct calibration.
• Remember that receipt of the calibration signal depends on the time shown on the
digital display. The receive operation will be performed whenever the digital display
shows 2:00 AM and 4:00 AM, regardless of whether or not that is actually the correct
time.
2:00 AM
4:00 AM
2 to 6 minutes
< First receipt >
2 to 6 minutes
< Second receipt >
• When both receipts are successful, the watch uses the data of the second receipt for
calibration. When only one receipt is successful, the watch uses the data of the
successful receipt.
