•
The Tide Graph flashes as shown below to indicate the tide range.
•
The segments on either end of the Tide Graph flash during high tide.
Lunitidal Interval
Theoretically, high tide is at the Moon’s transit over the meridian and low tide is about
six hours later. Actual high tide occurs somewhat later, due to factors such as
viscosity, friction, and underwater topography. Both the time differential between the
Moon’s transit over the meridian until high tide and the time differential between the
Moon’s transit over the meridian until low tide are known as the “lunitidal interval”.

code starts to flash, which indicates the setting screen.
2. Press
C
nine times until the current button operation
tone setting (
or
) appears.
3. Press
D
to toggle the setting between
(tone on)
and

Power Saving Function
When turned on, the Power Saving function enters a
sleep state automatically whenever the watch is left in an
area for a certain period where it is dark. The table below
shows how watch functions are affected by the Power
Saving function.

•
Wearing the watch inside the sleeve of clothing can cause it to enter the sleep state.
E-84
•
The watch will not enter the sleep state between 6:00 AM and 9:59 PM. If the watch
is already in the sleep state when 6:00 AM arrives, however, it will remain in the
sleep state.
To recover from the sleep state
Perform any one of the following operations.
•
Move the watch to a well-lit area.
•
Press any button.
•
Angle the watch towards your face for reading (page E-57).
To turn Power Saving on and off
1. In the Timekeeping Mode, hold down
A
until the city
code starts to flash, which indicates the setting screen.
2. Press

Radio-controlled Atomic Timekeeping Precautions
•
Strong electrostatic charge can result in the wrong time being set.
•
The time calibration signal bounces 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 the 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.
E-86
•
If you are in an area where proper time calibration signal reception is impossible, the
watch keeps the time with the precision noted in “Specifications”.
•
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, and DST
(summer time) settings (page E-68), and auto receive settings (page E-30).
•
The Home City setting reverts to the initial default of
TYO
(Tokyo) whenever the
battery power level drops to Level 5 or when you have the rechargeable battery
replaced. If this happens, change the Home City to the setting you want (page E-14).
Transmitters
The time calibration signal received by this watch depends on the currently selected
Home City code (page E-14).
•
When a U.S. time zone is selected, the watch receives the time calibration signal
transmitted from the United States (Fort Collins).
•
When a Japanese time zone is selected, the watch receives the time calibration
signal transmitted from Japan (Fukushima and Fukuoka/Saga).
•
When a European time zone is selected, the watch receives the time calibration
signals transmitted from Germany (Mainflingen) and England (Anthorn).
E-87
•
When a China time zone is selected, the watch receives the time calibration signals
transmitted from China (Shangqiu City).
•
When your Home City is
LIS
,
LON
,
MAD
,
PAR
,
ROM
,
BER
,
STO
,
ATH
,
MOW
(which can receive both the Anthorn and Mainflingen signals), the watch first tries to
pick up the signal it last successfully received. If that fails, it tries the other signal. For
the first receive after you select your Home City, the watch tries the nearest signal
first (Anthorn for
LIS
,
LON,
Mainflingen for
MAD
,
PAR
,
ROM
,
BER
,
STO
,
ATH
, and
MOW
).
Auto Return
•
If you do not perform any operation for about two or three minutes while a setting
screen (with a flashing setting) is on the display, the watch will exit the setting screen
automatically.
Scrolling
The
B
and
D
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 at high speed.
E-88
Initial Screens
When you enter the World Time Mode or Alarm Mode, the data you were viewing
when you last exited the mode appears first.
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 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.
•
The current time for all city codes in the Timekeeping Mode and World Time Mode is
calculated in accordance with the Coordinated Universal Time (UTC) for each city,
based on your Home City time setting.
E-89
World Time
•
The seconds count of the World Time is synchronized with the seconds count of the
Timekeeping Mode.
Illumination Precautions
•
The electro-luminescent panel that provides illumination loses power after very long
use.
•
Illumination may be difficult 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
•
Avoid wearing the watch on the inside of your wrist. Doing so causes the auto light
switch to operate when it is not needed, which shortens battery life. If you want to
wear the watch on the inside of your wrist, turn off the auto light switch feature.
