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 leav e the watch in the Alarm (except f or the target alar m screen explained on
“T o set an alarm time” ), Date Aler t, or Hand Setting Mode for two or three min utes
without performing any oper ation, it automatically changes to the Timekeeping
Mode.
• If you leav e the watch with a flashing setting or cursor on the display f or two or three
minutes without perf or ming any operation, it automatically sav es any settings you
hav e made up to that point and exits the setting screen.
Scrolling
The B and D buttons are used in v ar ious 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.
Initial Screens
When you enter the World Time, Alarm, or Date Aler t Mode, the data you were
viewing when you last e xited the mode appears first.
Radio-controlled Timekeeping Precautions
• Strong electrostatic charge can result in the wrong time being set.
• 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 ma y change the reception range of the signal and make reception temporarily
impossible .
• Even if the time calibr ation signal is received properly , cer tain 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
ov er any time settings you make .
• The watch is designed to automatically update the date and da y 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 receiv e signals that differentiate between leap years and non-leap
years .
• Though this watch is designed to receiv e both time data (hour, minutes , seconds)
and date data (year , month, day), certain signal conditions can limit reception to time
data only .
