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 Atomic 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 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 update the date and day of the week
automatically for the period January 1, 2000 to December 31, 2099. Setting
of the date by a 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.
Timekeeping
•
Resetting the seconds to
00
while the current count is in the range of 30 to
59 causes the minutes to be increased by 1. In the range of 00 to 29, the
seconds are reset to
00
without changing the minutes.
•
The day of the week is displayed automatically in accordance with the date
(year, month, and day) settings.
•
The year can be set in the range of 2000 to 2099.
•
The watch’s built-in full automatic calendar makes allowances for different
month lengths and leap years. Once you set the date, there should be no
reason to change it except after you have the watch’s battery replaced or
when battery power drops to Level 5.
•
The times for the Timekeeping Mode and all the city codes of the World
Time Mode are calculated in accordance with each city’s UTC differential.
•
The UTC differential is a value that indicates the time difference between a
reference point in Greenwich, England and the time zone where a city is
located.
•
The letters “UTC” is the abbreviation for “Coordinated Universal Time”,
which is the world-wide scientific standard of timekeeping. It is based upon
carefully maintained atomic (cesium) clocks that keep time accurately to
within microseconds. Leap seconds are added or subtracted as necessary
to keep UTC in sync with the Earth’s rotation.
12-hour/24-hour Timekeeping Formats
The 12-hour/24-hour timekeeping format you select in the Timekeeping Mode
also is applied in all other modes.
•
With the 12-hour format, the PM indicator (
P
) appears on the display for
times in the range of noon to 11:59 p.m. and no indicator appears for times
in the range of midnight to 11:59 a.m.
•
With the 24-hour format, times are displayed in the range of 0:00 to 23:59,
without any indicator.
Illumination Precautions
•
The electro-luminescent panel that provides illumination loses power after
very long use.
•
Illumination may be hard to see when viewed under direct sunlight.
•
The watch may emit an audible sound whenever the display is illuminated.
This is due to vibration of the EL panel used for illumination, and does not
indicate malfunction.
•
Illumination turns off automatically whenever an alarm sounds.
•
Frequent use of illumination runs down the battery.
Auto light switch precautions
•
The auto light switch is turned off automatically whenever battery power is
at Level 4.
•
Wearing the watch on the inside of your wrist, movement of your arm, or
vibration of your arm can cause frequent activation of the auto light switch
and illumination of the display. To avoid running down the battery, turn off
the auto light switch whenever engaging in activities that might cause
frequent illumination.
•
Note that wearing the watch under your sleeve while the auto light switch is
turned on can cause frequent illumination of the display and can run down
the battery.
•
Illumination may not turn on if the face of the
watch is more than 15 degrees above or below
parallel. Make sure that the back of your hand
is parallel to the ground.
•
Illumination turns off in about one second, even
if you keep the watch pointed towards your
face.
•
Static electricity or magnetic force can interfere with proper operation of the
auto light switch. If illumination does not turn on, try moving the watch back
to the starting position (parallel with the ground) and then tilt it back towards
your face again. If this does not work, drop your arm all the way down so it
hangs at your side, and then bring it back up again.
•
Under certain conditions, illumination may not turn on until about one
second after you turn the face of the watch towards you. This does not
necessarily indicate malfunction of the auto light switch.
•
You may notice a very faint clicking sound coming from the watch when it is
shaken back and forth. This sound is caused by mechanical operation of
the auto light switch, and does not indicate a problem with the watch.
