Viewing Altitude Records
You can use the Data Recall Mode to view manually saved record data and auto save values.
To view altitude records
1. Use
B
to select the Data Recall Mode (
RECALL
) as shown on page E-20.
• About one second after RE
CALL appears on the display, the display will change to show the fi rst
record of the memory area you were viewing when you last exited the Data Recall Mode.
2. Use
A
and
C
to scroll through the memory area screens and display the one you want.

Thermometer Precautions
• Temperature readings are affected by your body temperature, direct sunlight, and moisture. To achieve
a more accurate temperature reading, remove the watch from your wrist, place it in a well ventilated
location out of direct sunlight, and wipe all moisture from the case. It takes approximately 20 to 30
minutes for the case of the watch to reach the surrounding temperature.
E-68
Temperature Sensor Calibration
The temperature sensor built into the watch is calibrated at the factory and normally requires no further
adjustment. If you notice serious errors in the temperature readings produced by the watch, you can
calibrate the sensor to correct the errors.
Important!
• Incorrectly calibrating the temperature sensor can result in incorrect readings.
Carefully read the following before doing anything.
–
Compare the readings produced by the watch with those of another reliable and 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.
To calibrate the temperature sensor
1. Take a reading with another measurement device to determine the
exact current temperature.
2. Use
B
to enter the Thermometer Mode (
TEMP
), as shown on page E-20.
3. Pull out the crown. This will cause the current temperature reading
value to fl ash on the digital display.
4. Rotate the crown to adjust the temperature value.
• The calibration unit is 0.1°C (0.2°F).
• To return the currently fl ashing value to its initial factory default
s
etting, press
A
and
C
at the same time. OFF will appear at
the fl ashing location for about one second, followed by the initial
default value.
5. After you complete calibration, push the crown back in.

Taking Temperature Readings
This watch uses a temperature sensor to measure temperature.
To take temperature readings
Use
B
to select the Thermometer Mode (
TEMP
), as shown on page E-20.
• TEMP w
ill appear on the display, indicating that temperature
reading is in progress. The results will appear on the display after
about one second.
• After a temperature reading operation is started, the watch will
t
ake readings every fi ve seconds for the fi rst three minutes, and
then every two minutes after that.
• To restart a reading operation from the beginning, press
A
.
• The watch will return to the Timekeeping Mode automatically if you
d
o not perform any operation for about 1 hour after entering the
Thermometer Mode.
Temperature
• Temperature is displayed in units of 0.1°C (or 0.2°F).
• The displayed temperature value changes to
- -.-
°C (or °F) if a measured temperature falls outside the
range of –10.0°C to 60.0°C (14.0°F to 140.0°F). The temperature value will reappear as soon as the
measured temperature is within the allowable range.
Display Units
You can select Celsius (°C) or Fahrenheit (°F) as the display unit for the measured temperature value.
See “To specify altitude, barometric pressure, and temperature units” (page E-41).

E-66
To calibrate the pressure sensor
1. Take a reading with another measurement device to determine the
exact current barometric pressure.
2. Use
B
to enter the Barometer Mode (
BARO
), as shown on page E-20.
3. Pull out the crown. This will cause the current barometric pressure
reading value to fl ash on the digital display.
4. Rotate the crown to adjust the barometric pressure value.
• The calibration unit is 1 hPa (0.05 inHg).
• To return the currently fl ashing value to its initial factory default
s
etting, press
A
and
C
at the same time. OFF will appear at
the fl ashing location for about one second, followed by the initial
default value.
5. After you complete calibration, push the crown back in.
Barometer Precautions
• The pressure sensor 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 offi cial weather
prediction or reporting applications.
• Sudden temperature changes can affect pressure sensor readings. Because of this, there may be
some error in the readings produced by the watch.

• Note that power saving (page E-18) is disabled while barometric pressure change indicator display is
enabled.
• Note that barometric pressure change indicator display cannot be enabled while the watch’s battery is
low.
Pressure Sensor Calibration
The pressure sensor built into the watch are calibrated at the factory and normally require no further
adjustment. If you notice serious errors in the pressure readings produced by the watch, you can calibrate
the sensor to correct the errors.
Important!
• Incorrectly calibrating the barometric pressure sensor can result in incorrect readings. Before
performing the calibration procedure, compare the readings produced by the watch with those of
another reliable and accurate barometer.
E-64
Important!
• To ensure proper results, take barometric readings under conditions where the altitude remains
constant.
Example
– In a lodge or campground
– On the ocean
• A change in altitude causes a change in barometric pressure. Because of this, correct readings are
impossible. Do not take readings while ascending or descending a mountain, etc.
Enabling or Disabling Display of the Barometric Pressure Change Indicator
You can enable or disable display of the barometric pressure change indicator as desired. When display
of the indicator is enabled, the watch will take a barometric pressure reading every two minutes,
regardless of the mode it is in.
• When
BARO
is shown on the display, it means that barometric pressure change indicator display is
enabled.
• When
BARO
is not on the display, it means that barometric pressure change indicator display is
disabled.
To enable or disable the barometric pressure change indicator
In the Barometer Mode, hold down
D
for at least two seconds. Wait until
INFO
appears on the left side of
the display and the current setting (
ON
or
OFF
) fl
ashes on the right. Use this screen to enable or disable
the barometric pressure change indicator.
• If barometric pressure change indicator display is currently enabled,
BARO
will also appear in the
display.
BARO
will not appear if display is currently disabled.
• Note that barometric pressure change indicator display will turn off automatically 24 hours after you
turn it on or battery power goes low.
