•
The Moon phase indicator shows the Moon as viewed at noon from a position in the
Northern Hemisphere looking south. Note that at times the image shown by the
Moon phase indicator may differ from that of the actual Moon in your area.
•
The left-right orientation of the Moon phase is reversed when viewing from the
Southern Hemisphere or from a point near the equator.
Moon Phases and Moon Age
The Moon goes through a regular 29.53-day cycle during which it appears to wax and
wane due to how the Sun illuminates the Moon and the relative positioning of the
Earth, Moon, and Sun. The greater the angular distance between the Moon and the
Sun,
*
the more we see illuminated.
*
The angle to the Moon in relation to the direction at which the Sun is visible from the
Earth.
The Moon age indicates the number of days from the New Moon to any particular
phase. It is normally calculated using either noon or midnight as a reference point.
This watch calculates the Moon age based on the angular distance of the Moon at
noon, which can result in an error of
±
1 day. Because of this, the appearance of the
Moon phase indicator may be different from that of the actual Moon.
The watch uses the following formula to calculate Moon age.
Moon Age (days) = 29.53
×
(Moon angular distance / 360
°
)
Tide Graph
The wave on the watch’s tide graph indicates the current tide. indicates that the tide
is currently rising, while indicates a falling tide. Neither nor is on the display at
high tide and low tide.
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 lunitidal interval differs according to your current location, so you must
specify a lunitidal interval in order to obtain the correct tide graph readings.
Falling
Rising
High tide
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.”
When setting the lunitidal interval for this watch, use the time differential between the
Moon’s transit over the meridian until high tide.
See the “Site/Lunitidal Interval Data List” for lunitidal interval information around the
world.
Auto Return Feature
•
If you leave a screen with flashing digits on the display for two or three minutes
without performing any operation, the watch automatically saves any settings you
have made up to that point and exits the setting screen.
•
If you leave the watch in the Moon/Tide Data Mode and Alarm Mode for two or three
minutes without performing any operation, it automatically changes to the
Timekeeping Mode.
Data and Setting Scrolling
The
B
and
D
buttons 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 through the data at high speed.
Initial Screens
When you enter the Timekeeping, World Time, 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.
•
With the 12-hour format, the P (PM) indicator 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.
•
The year can be set in the range of 2000 to 2039.
•
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 when battery power drops to Level 4.
World Time
•
The seconds count of the World Time is synchronized with the seconds count of the
Timekeeping Mode.
•
The GMT differential is the time difference between the time zone where the city is
located and Greenwich Mean Time.
•
GMT differential is calculated by this watch based on Universal Time Coordinated
(UTC) data.
Backlight Precautions
•
The electro-luminescent panel that provides illumination loses power after very long
use.
•
The illumination provided by the backlight 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.
•
The backlight automatically turns off whenever an alarm sounds.
•
Frequent use of the backlight runs down the battery.
Auto light switch precautions
•
Wearing the watch on the inside of your wrist, as well as movement or vibration of
your arm can cause the auto light switch to activate and illuminate the display. To
avoid running down the battery, turn off the auto light switch whenever engaging in
activities that might cause frequent illumination of the display.
•
Note that wearing the watch under your sleeve while the auto light switch is turned
on can cause frequent illumination of the face and can run down the battery.
•
The backlight may not light 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.
•
The backlight 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 the backlight does not light, try moving the watch back to the starting
position (parallel with the ground) and then tilt it back toward you 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, the backlight may not light until about one second after you
turn the face of the watch towards you. This does not necessarily indicate
malfunction of the backlight.
•
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.

Wearing the watch inside the sleeve of clothing can
cause it to enter the sleep state.
•
The watch will not enter the sleep state between 6:00 AM and 10:59 PM. If the
watch is already in the sleep state when 6:00 AM arrives, however, it will remain in
the sleep state.
•
The watch will not enter the sleep state while it is in the Countdown Timer Mode or
Stopwatch Mode.
To recover from the sleep state
Perform any one of the following operations.
•
Move the watch to a well-lit area.
•
Press any button.
