Lunitidal Interval
About the Auto Light Switch
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.
Turning on the auto light switch causes illumination to turn on, whenever you position
your wrist as described below in any mode, except for the Hand Setting Mode setting
screen.
Moving the watch to a position that is parallel to the ground and then tilting it towards
you more than 40 degrees causes illumination to turn on.
• Wear the watch on the outside of your wrist.

The temperature sensor built into the watch is calibrated at the factory and normally
requires no further adjustment. If you notice serious errors in the temperature readings
produced by the watch, you can calibrate the sensor to correct the errors.
Important!
Incorrectly calibrating the temperature sensor can result in incorrect readings.
Carefully read the following before doing anything.
• Compare the readings produced by the watch with those of another reliable and
accurate thermometer.
Warning!
• Always make sure you are in a safe place whenever you are reading the
display of the watch using the auto light switch. Be especially careful when
running or engaged in any other activity that can result in accident or injury.
Also take care that sudden illumination by the auto light switch does not
startle or distract others around you.
• If adjustment is required, remove the watch from your wrist and wait for 20 or 30
minutes to give the temperature of the watch time to stabilize.
To calibrate the temperature sensor
1. In the Timekeeping Mode, hold down A until the
seconds start to flash, which indicates the setting
screen.
2. Press C nine times to display the temperature sensor
calibration screen.
• When you are wearing the watch, make sure that its auto light switch is turned
off before riding on a bicycle or operating a motorcycle or any other motor
vehicle. Sudden and unintended operation of the auto light switch can create a
distraction, which can result in a traffic accident and serious personal injury.
3. Use D (+) and B (–) to change the calibration value.
• You can change the value in 0.1ºC (0.2ºF) steps, in a
range of 10ºC ( 18ºF). The calibration value shows

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.
Moon Phases and Moon Age
Timekeeping
The Moon goes through a regular 29.53-day cycle. During each cycle, the Moon
appears to wax and wane as the relative positioning of the Earth, Moon, and Sun
changes. The greater the angular distance between the Moon and the Sun,* the more
we see illuminated.
• 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 the A (AM) 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 angle to the Moon in relation to the direction at which the Sun is visible from the
Earth.
This watch performs a rough calculation of the current Moon age starting from day 0
of the moon age cycle. Since this watch performs calculations using integer values
only (no fractions), the margin for error of the displayed Moon age is 1 day.
• 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 batteries replaced.
Tide Graph
The wave on the watch’s tide graph indicates the current tide.
High tide
World Time
• The seconds count of the World Time is synchronized with the seconds count of the
Timekeeping Mode.
• All World Time Mode times are calculated from the current time in the Timekeeping
Mode using UTC time differential values.
Low tide
• 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.
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.
The tide graph displayed by this watch is based on the current Moon age.
Remember that the margin for error of the Moon age displayed by this watch is
day. The greater the error in a particular Moon age, the greater the error in the
resulting tide graph.

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.

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.
More than 15 degrees
too high
• 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.
