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.
A rising graph generally means
better weather.
A falling graph generally means
deteriorating weather.
Note that if there are sudden
changes in weather or tem-
perature, the graph line of past
measurements 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
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.
To calibrate the barometric pressure
1. In the Timekeeping Mode, use D to
display the barometric pressure and

THERMOMETER FUNCTIONS

A built-in temperature sensor measures temperature and shows the measured
value on the display. The thermometer can be calibrated.
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 measurements
Temperature measurements are taken automatically every five minutes,
regardless of what mode the watch is in. Measured temperature values can be
viewed in the Timekeeping or Altimeter Mode. Temperature measurements
are taken every five seconds for the first three minutes after you display the
Timekeeping Mode's Barometric Pressure/Temperature screen, or after you
enter the Altimeter Mode. After that, temperature measurements are taken
every five minutes.
• Temperature measurement data can be recalled along with altitude
measurement data.
Understanding the temperature display
1. Use C to enter the Timekeeping Mode.
2. Press D to display the Barometric Pressure/Temperature screen.

If you do not press any button for 10 or 11 hours, the watch automatically
returns to the Timekeeping screen.

• The display shows "– –.– °C" if a measured value falls outside the range of
–20.0°C to 60.0°C. The normal display will return as soon as the
temperature returns within the allowable range.
• For details on viewing the temperature in the Altimeter Mode, see
"Understanding the altimeter display".

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 adjustment 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.

• Note that the accuracy of data measured by the trekking counter can be
affected when you are walking on sand or other soft ground, on a steep
upgrade, on a steep downgrade, or on stairs.
• Be sure to take care not to drop the watch while walking.
• To improve the accuracy of measured data, be sure to turn off the trekking
counter whenever you are taking a break or stop walking for any other reason.
