• The backlight may not illuminate if the face of the watch is more than 15
degrees off parallel as shown below. 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 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.
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 backlight
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 backlight can create a distraction, which can
result in a traffic accident and serious personal injury.

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.
• Press B to switch between the 12-hour and 24-hour formats.
5. While any other digits (besides seconds) are selected (flashing), press D
to increase the number. Holding down D changes the current selection at
high speed.
6. After you set the time and date, press A to return to the Timekeeping
Mode (Timekeeping Display).
• 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 selection is
flashing, the flashing stops and the watch goes back to the Timekeeping
Mode automatically.
TIMEKEEPING FUNCTION
To set the time and date
1. In the Timekeeping Mode, press D until
the Timekeeping Display appears.
2. Hold down A until the seconds digits start
to flash on the display. The seconds digits
flash because they are
selected .
3. Press C to change the selection in the

Example barometer applications
• Before going mountain climbing, you can take readings to find out the
probable upcoming weather.
• You can predict the weather for golf or other outdoor activities.
About barometric measurements
The barometer automatically takes measurements every two hours (starting
from midnight), regardless of what mode you are in. Barometric pressure
measurements are also taken every five seconds for three minutes after you
display the Timekeeping Mode’s Barometric pressure/Temperature display.
The last measurement result, along with the current temperature is displayed
in the Barometric pressure/Temperature display.
Understanding the barometer display
1. Use C to enter the Timekeeping Mode.
2. Press D to display the Barometric Pressure/Temperature Display.
*
1 The barometric pressure graph shows the barometric readings for the
past 26 hours. The flashing point on the right of the display is the point for
the last measurement.

2 Some countries call this unit hecto-pascal (hPa), while other countries
call it millibars (mb). It really makes no difference, because 1 hPa = 1 mb.
In this manual, we will refer to hPa/mb or hPa (mb).
*
3 The display shows “– – – – hPa/mb” if a measured value falls outside the
range of 460 hPa/mb to 1100 hPa/mb. The normal display will return as
soon as the pressure returns within the allowable range.
Using the barometric pressure graph
Changes in barometric pressure are caused by changes in the weather and
temperature. The following shows how to interpret the data that appears on
the barometric pressure graph.
Note that if there are sudden
changes in weather or tempera-
ture, the graph line of past meas-
urements may run off the top or
bottom of the display. The entire
graph will become visible once
barometric conditions stabilize.
The following conditions cause the barometric pressure measurement to be
skipped, with the corresponding point on the barometric pressure graph
being left blank.
• Barometric reading that is out of range (460 hPa/mb to 1100 hPa/mb)
• Sensor malfunction
• Dead battery
Not visible on display
A rising graph generally means better
weather.
A falling graph generally means
deteriorating weather.
Calibrating the barometric pressure measurement
The 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
barometric pressure readings produced by the watch, you can adjust it to
correct the error.
Important!
Incorrectly calibrating the barometric pressure measurement of this watch
can result in incorrect readings. Compare the readings produced by the
watch with those of another reliable accurate barometer.
BAROMETER FUNCTIONS
This watch uses a pressure sensor to measure air pressure. This sensor can
be calibrated.
Important!
The barometer that is built into this watch measures changes in air pressure,
which you can then apply to your own weather predictions. It is not intended
for use as a precision instrument in official weather prediction or reporting
applications.
To calibrate the barometric pressure
1. In the Timekeeping Mode, use D to
display the barometric pressure and
temperature.
2. Hold down A until the display clears.
“OFF” or the temperature value should be
flashing on the display.
