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.
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 X (Moon angular distance / 360
°
)
Moon Phase Indicator
The Moon phase indicator of this watch indicates the current phase of the Moon as
shown below.

•
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.
•
The Moon phase indicator refreshes each day at midnight.
Fishing/Hunting Time Calculation
The fishing/hunting times calculated by this watch are based on the long experience
of fishermen and hunters that the movements of the moon and tides affect fish and
game. The following explains how the moon’s transit (position) affects the feeding
patterns of fish and game.
•
During the month, the most feeding action can be
expected on the day of the New Moon and Full Moon,
making them the best for hunting and fishing. Favorable
conditions with less action can be expected on the day
of the First Quarter and Last Quarter as well.
•
On a daily basis, optimum hunting and fishing conditions
occur at the upper transit (hour angle= 0h) and the lower
transit (hour angle = 12h). Other less favorable
conditions can be expected at the west transit (hour
angle 6h) and east transit (hour angle = 18h).
•
The upper transit is when the Moon reaches its highest
point relative to your current location, while the lower
transit is when the Moon reaches its lowest point. The
time it takes to perform one cycle from one upper transit
to the next upper transit is the “lunar day”. Due to the
relationship between the Earth’s rotation and the Moon’s
orbit, the length of the lunar day is 24 hours and
50 minutes.
•
Note that water temperature, weather, atmospheric pressure, and other factors can
also affect fish and animal behavior.
Your watch calculates the current Moon age, phase, and transit (hour angle) for the
current date in relation to your Home Site, and then uses the calculated result to
calculate and display fishing/hunting time data.
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 exits the setting screen.
Scrolling
The
B
and
E
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.
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 12-hour/24-hour timekeeping format you select in the Timekeeping Mode is
applied in all modes.
•
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 after you have the watch’s battery replaced.

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 shortens battery life.
Auto light switch precautions
•
Wearing the watch on the inside of your wrist and 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.
•
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 two seconds, 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.
