ABOUT THE BACKLIGHT

About the Auto Light Switch Function

When the auto light switch function is turned on, the backlight automatically turns on
for two seconds under the conditions described below. Avoid wearing the watch on the
inside of your wrist. Doing so causes the backlight to operate when not needed, which
shortens battery life.

Parallel to
ground

40°

• The backlight may not illuminate if the face of the watch is more than 15 degrees off
parallel to the left or right. Make sure that the back of your hand is parallel to the
ground.

• Static electricity or magnetic force can interfere with proper operation of the auto
light switch function. If the backlight does not illuminate, 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 or less
after turn the face of the watch towards you. This does not necessarily indicate
malfunction of the backlight.

Caution

• The backlight of this watch employs an electro-luminescent (EL) light, which loses its
illuminating power after very long term use.

• Frequent use of the backligfht shortens the battery life.

• The watch emits an audible sound whenever the display is illuminated. This is because the
EL light vibrates slightly when lit. It does not indicate malfunction of the watch.

Warning!

• Never try to read your watch when mountain climbing or hiking in areas that are dark
or in areas with poor footing. Doing so is dangerous and can result in serious
personal injury.

• Never try to read your watch when running on a roadside or in any other location
where there might be vehicular or pedestrian traffic. Doing so is dangerous and can
result in serious personal injury.

• Never try to read your watch when riding on a bicycle or when operating a motorcycle
or any other motor vehicle. Doing so is dangerous and can result in a traffic accident
and serious personal injury.

•

When you are wearing the watch, make sure that its auto light switch function is turned
off before riding on a bicycle or operating a motorcycle or any other motor vehicle.

Sudden and unintended operation of the backlight can create a distraction, which can

result in a traffic accident and serious personal injury.

THERMOMETER FUNCTIONS

A built-in temperature sensor measures temperature and shows the measured value
on the display. The thermometer can be calibrated to correct for errors.

Important

Temperature measurements are affected by your body temperature (while you are
wearing the watch), direct sunlight, and moisture. To achieve a more accurate
temperature measurement, remove the watch from your wrist, place it in a well
ventilated location out of direct sunlight, and wipe off all moisture from the case. It
takes approximately 20 to 30 minutes for the case of the watch to reach the actual
surrounding temperature.

Accurate temperature measurements cannot be achieved while you are wearing the
watch. The following graph illustrated affects of body temperature on actual
temperature.

what mode the watch is in. You can see the measured values in the Timekeeping
Mode’s Temperature Display.

Understanding the temperature display

1. Use CCto enter the Timekeeping Mode.

2. Press DDto display the Temperature Display.

• Whenever you switch to the Temperature Display, the
current temperature is measured and displayed.

* The display shows “– . – °C” if a measured value falls

outside the range of –20°C to 60°C.
The normal display will return as soon as the temperature
returns within the allowable range.

Calibrating the Temperature Measurement

The temperature sensor of this watch is calibrated at the factory before shipment and
further adjustment is normally not required. If noticeable error is found in the
temperature readings produced by the watch, you can adjust it to correct the error.

Important

Incorrectly calibrating the temperature measurement of this watch can result in
incorrect readings. Carefully read the following before doing anything.

• Compare the readings produced by the watch with those of another reliable,
accurate thermometer.

• If calibration 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.

• Perform the temperature calibration before procedure as quickly as possible to avoid
the temperature of the watch being affected by your body temperature.

• You can also preform temperature calibration underwater, if the water temperature is
stable.

To calibrate the temperature

1. Use CCto enter the Timekeeping Mode and press DDto
display the Temperature Display.

2. Holding down AAand the current temperature digits
flash.

3. Each press of DDincrease the displayed temperature by

0.1°C, and pressing the BBdecrease it by 0.1°C.

• You can calibrate the temperature within a range of

–9.9°C to +9.9°C.

• Press BBand DDat the same time to rest the temperature

calibration to the factory setting.

4. After calibrating the temperature, press AAto return to
the Temperature Display.

TIDE GRAPH MODE

Before using the Tide Graph Mode, be sure to first carefully set the current time, your
current location, and the lunitidal interval.

About the lunitidal interval

The lunitidal interval is the period from the moon’s upper transit (moon up) to high tide.
If you know the lunitidal interval, tide changes can be determined using the moon age.
This watch calculates tide changes according to the current time and the location
setting, and displays them graphically.

To calculate the lunitidal interval

1.Look up the high tide time for the flood tide of the location whose tide changes you
want to know.

2.Use this watch to look up the moon up time that occurs immediately before this time.

3.Subtracting the moon up time from the high tide time produces the lunitidal interval.

To set the lunitidal interval

1. In the Moon Data Mode, hold down AAuntil both
sides of the Tide Graph and hour digits start to
flash, as shown below.

• You can also start this procedure by holding down

AA

while in the Tide Graph Mode.

2. Use CCto select the digit whose setting you want
to change. Each press of CCmoves the flashing to
the next digit.

3. Use DDto increase the flashing digit or BBto
decrease it. Holding down either button changes
the setting at high speed.

4. After you are finished making the lunitidal setting
you want, press AAto enter the Tide Graph Mode.

About the Tide Graph Mode

The Tide Graph Mode shows the changing of the tides in graphic form. The graph
uses time (advancing from left to right) as the horizontal axis, and tide change as the
vertical axis.

• You can enter the Tide Graph Mode by pressing AAwhile in the Moon Data Mode.
Though you can change the time setting while in the Tide Graph Mode, you cannot
change the month or day setting. To display the tide graph for another date, return to
the Moon Graph Mode, change the date setting, and then enter the Tide Graph
Mode again. Also note that you cannot directly change the month setting in the Moon
Data Mode. The month setting changes automatically as you increase or decrease
the day setting.

• The Tidal Graph is also on the display in the Timekeeping Mode, where it indicates
the tide for the current time.
