TIMEKEEPING MODE
You can select display of either the current date (month
and day) or temperature in the Timekeeping Mode.
Press
B B to toggle between the date and temperature
display.
To set the time and date
1. While the current date (not the temperature) is
displayed in the Timekeeping Mode, hold down A A
until the seconds digits flash on the display.
2. Press C C to change the selection (flashing) in the
following sequence.
3. While the seconds setting is selected (flashing), press E E to reset it to 00. If you
press E E while the seconds setting is in the range of 30 to 59, the seconds are reset
to 00 and 1 is added to the minutes. If the seconds setting is in the range of 00 to
29, the minutes count is unchanged.
4. While any other setting (besides seconds) is selected (flashing), press E E to
increase it or B B to decrease it. While the 12/24-hour format setting is selected,
press E E to toggle it between 12 and 24.
· Except for the seconds or 12/24-hour setting, holding down a button changes the
setting at high speed.
5. After you set the time and date, press A A to return to the Timekeeping Mode.
· The day of the week is automatically set in accordance with the date.
· 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 setting is flashing, the
flashing stops and the watch goes back to the Timekeeping Mode automatically.
Current Temperature Display
A built-in temperature sensor measures temperature and shows the measured value
on the display. The readout from the temperature sensor can also be switched
between Celsius (°C) and Fahrenheit (°F). 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.

About Temperature Measurement
· A temperature measurement operation is performed
whenever you switch from month-day display to
temperature display.
· Temperature measurements are performed and the
temperature value is updated every two minutes while
the current temperature is displayed.
· Pressing E E while the current temperature is displayed
executes a temperature measurement operation and
stores the result in memory along with the time of the
measurement.
· At the top of each hour, the current temperature is
measured and stored in memory along with the time of
the measurement.
* The display shows “– – . – °C (or °F)” if a measured value falls outside the range of
–20°C to 60°C (–4°F to 140°F). The normal display will return as soon as the
temperature returns within the allowable range.
· Memory can hold up to 100 temperature data entries, which are managed on a first-
in, first-out basis. See “TEMPERATURE DATA RECALL MODE” of this manual for
details on how to recall memory data.
· The first data item is stored as data item 1, the second as data item 2, and so on up
to 100 data items.
· When a new data item is stored while there are already 100 data items (numbered 1
to 100) in memory, the new data item is “pushed” into memory from the top (on top of
item 100). This shifts all of the previous data items down one position (item 100
becomes item 99, 99 becomes 98, and so on), and item 1 is deleted.

Switching between Celsius and Fahrenheit
1. Hold down A A while in the Current Temperature
Display and the current temperature digits flash.
2. Press C C to select either Celsius “°C” or Fahrenheit
“°F”.
3. After you select the Celsius or Fahrenheit, press A A to
return to the Temperature Display.
· 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 Current Temperature Display
automatically.
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 perform temperature calibration underwater, if the water temperature is
stable.
To calibrate the temperature
1. Hold down A A while in the Current Temperature
Display and the current temperature digits flash.
2. Each press of E E increase the displayed temperature
by 0.1°C, and pressing the B B decrease it by 0.1°C.
· If you have selected Fahrenheit as your unit of
measurement, the above operations change the
reading by 0.2°F.
· You can calibrate the temperature within a range of
–9.9°C to +9.9°C (–18.0°F to +18.0°F).
· Press B B and E E at the same time to reset the
temperature calibration to the factory setting.
3. After calibrating the temperature, press A A to return to the Current Temperature
Display.
· 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 Current Temperature Display
automatically.
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.

· 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 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.
