• After you change a setting in the above procedure, the watch needs a bit of time to
calculate certain information. During this calculation, the patterns in the graphic
display move at high speed. Wait until the patterns stop moving before you try to
input any further data.
• If you set the current time forward one hour for daylight saving time (summer time),
be sure to also increase the setting for your difference from Greenwich Mean Time
(see “To set location data” below). Of course, you should remember to adjust the
other way (by decreasing the difference) when you go back to standard time.

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 auto light switch to operate when not
needed, which shortens battery life.
Moving the watch to a position that is parallel to the ground and then tilting it towards
you approximately 40 degrees causes the backlight to illuminate.
Parallel to
ground
• 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.
Parallel to ground More than 15 degrees
• Static electricity or magnetic force can interfere with proper operation of the auto
backlight function. If the auto 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.
To switch the auto light switch function on and off
In the Timekeeping Mode, hold down D for one or two seconds to turn the auto light
switch function on and off.
• The auto light switch indicator is shown on the display in all modes while the auto
light switch function is on.
• In order to protect against running down the battery, the auto light switch function is
automatically turned off approximately three hours after you turn it on. Repeat the
above procedure to turn the auto light switch function back on if you want.
• Pressing B while in the Timekeeping Mode illuminates the display, regardless of the
auto light switch's on/off setting.
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 where there is the danger of accidents,
especially in locations 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 auto light switch can create a distraction,
which can result in a traffic accident and serious personal injury.

A built-in temperature sensor measures temperature and shows the measured value
THERMOMETER FUNCTIONS
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.

About Temperature Measurement
Temperature measurements are taken automatically every two minutes, regardless of
what mode the watch is in. You can see the measured values in the Timekeeping
Mode’s Temperature Display.

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.

• You can calibrate the temperature within a range
of –9.9°C to +9.9°C.
• Press B and D at the same time to rest the

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.
