Button Operation Tone
The button operation tone sounds any time you press one
of the watch's buttons. You can turn the button operation
tone on or off as desired.
Even if you turn off the button operation tone, alarms,
the Hourly Time Signal, and other beepers all operate
normally.

To turn the button operation tone 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 C nine times until the current button operation

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 C 11 times until the Power Saving on/off screen
appears.
3. Press D to toggle Power Saving on (
4. Press A twice to exit the setting screen.
The Power Saving indicator is on the display in all
modes while Power Saving is turned on.

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-29).
The Home City setting reverts to the initial default of
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-13).
Transmitters
The time calibration signal received by this watch depends on the currently selected
Home City code (page E-13).
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).

Tidal Movements
Tides are the periodic rise and fall of the water of oceans, seas, bays, and other
bodies of water caused mainly by the gravitational interactions between the Earth,
Moon and Sun. Tides rise and fall about every six hours. The Tide Graph of this watch
indicates tidal movement based on the Moon's transit over a meridian and the lunitidal
interval. The Tide Graph calculates and graphically represents current tide conditions
in your currently selected site or USER site based on longitudes, lunar day length, and
lunitidal interval preset in watch memory, and on high tide times specified by you.
The Tide Graph flashes as shown below to indicate the tide range.
Low tide
High tide
The segments on either end of the Tide Graph flash during low 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". Tide
data is calculated using the lunitidal intervals preset for each site.
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.
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.
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.
The watch will return to the Timekeeping Mode automatically if you do not perform
any operation for two or three minutes in the Tide/Moon Data Mode.
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.
