alarm time is reached.You can also turn on an Hourly  
Time Signal, which will cause the watch to beep twice  
every hour on the hour.  
The measurements the watch takes at the top and the bottom of each hour are stored  
in memory automatically. Memory can hold up to 50 measurement records.You can  
use the Temperature Data Recall Mode to recall memory data when you need it.  
Temperature data records are assigned numbers automatically starting from 01.  
When there are already 50 records in memory, storage of a new temperature  
reading causes the oldest record (record number 50) to be deleted automatically to  
make room for the new data. The new data is assigned record number 1, and all of  
the numbers of all the other records (01 to 49) are incremented by 1 (becoming 02  
through 50).

Lunitidal Interval  
About the Auto Light Switch  
Theoretically, high tide is at the Moons 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  
Moons transit over the meridian until high tide and the time differential between the  
Moons 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  
Moons 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.

More than  
40°  
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

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.  
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 watchs 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 watchs batteries replaced.  
Tide Graph  
The wave on the watchs 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 Earths  
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 Moons 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.

Static electricity or magnetic force can interfere with proper operation of the auto  
light switch. If illumination does not turn on, 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, illumination may not turn on until about one second after  
you turn the face of the watch towards you. This does not necessarily indicate  
malfunction of the auto light switch.

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.
