GENERAL GUIDE
TIMEKEEPING FUNCTIONS
There are two different displays in the Timekeeping Mode: a
Timekeeping Display and a Temperature Display. Use
D to
switch between them.
• Both the Timekeeping Display and the Temperature Display
show the temperature bar graph.
• Holding down A while the Timekeeping Display is shown
enters the time and date setting mode. Holding down A
while the Temperature Display is shown enters the
temperature calibration mode.
• When in the Timekeeping Mode, press B to illuminate the
display.
To set the time and date
1. Press D to display the timekeeping display (with the month
and date).
2. Hold down A and the seconds digits flash on the display
because they are selected.
3. Press C to change the selection in the following sequence.
4. While the seconds digits are selected (flashing), press D to reset the seconds to “00”. If you
press D while the seconds count is in the range of 30 to 59, it is reset to “00” and 1 is added
to the minutes. If the seconds count is in the range of 00 to 29, the minutes count is
unchanged.
5. While any other digits (besides seconds) are selected (flashing), press D to increase the
number or B to decrease it. Holding down either button changes the current selection at high
speed.
• While the 12/24-hour setting is selected, press D to switch between the two formats.
6. After you set the time and date, press A twice to return to the timekeeping display.
• The date can be set within the range of January 1, 1995 to December 31, 2039.
• If you do not operate any button for a few minutes while a selection is flashing, the flashing
stops and the watch goes back to the timekeeping display automatically.
Important
• 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.
To set the location data
1. Use C to enter the Timekeeping Mode.
2. Press D to display the Timekeeping Display.
3. Holding down A and the seconds digits flash on the display.
4. Press A again to display the location data. The GMT
differential data is flashing because it is selected.
5. Press C to change the selection in the following sequence.
6. While the GMT differential is selected (flashing), press D to
increase the value. Holding down D changes the current
selection at high speed.
7. While Longitude/Latitude is selected (flashing), press D to change the value of longitude or
B to change the value of latitude. Holding down either button changes the corresponding
setting at high speed.
8. After you set the location data, press A to return to the Timekeeping Display.

ABOUT THE BACKLIGHT
• While in the Timekeeping Mode, press B to illuminate the display.
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.
• Press C to change from mode to mode.
• After you perform an operation in any mode, pressing C returns to the Timekeeping Mode.

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.

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.
Understanding the temperature display
1. Use C to enter the Timekeeping Mode.
2. Press D to 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 C to enter the Timekeeping Mode and press D to
display the Temperature Display.
2. Holding down A and the current temperature digits flash.
3. Each press of D increase the displayed temperature by
0.1°C, and pressing the B decrease it by 0.1°C.
• 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 temperature
calibration to the factory setting.
4. After calibrating the temperature, press A to return to the
Temperature Display.
