5. After you select the measurement unit you want, press A to return to the
Altimeter Mode screen.
Note that all measurement data currently in memory is also deleted
whenever you change the barometric pressure, altitude, or temperature unit
of measurement
Setting a reference altitude
After you set a reference altitude, the watch automatically calculates the
difference between the current altitude and your preset value. The altitude
measurements produced by this watch are subject to error caused by changes
in barometric pressure. Because of this, we recommend that you set the
reference altitude during your climb whenever one is available.
1. Use C to enter the Altimeter Mode.
2. Hold down A until OFF or the current reference altitude value flashes on
the display.
OFF appears when the factory setting is currently set as the reference
altitude value.
3. Each press of D increases the displayed altitude by 5 m, while pressing
B decreases it. Holding down either button changes the value at high
speed.
If you have selected feet as your unit of measurement, the above
operations change the reading by 20 feet.
You can set the reference altitude within the range of 6,000 meters to
6,000 meters (19,680 feet to 19,680 feet).
Pressing B and D at the same time returns to the OFF setting.
4. After setting the reference altitude you want, press A to return to the
Altimeter Mode screen.
THERMOMETER MODE
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 temperature of the surrounding air.
About temperature measurements
The watch takes temperature measurements every five seconds for the first
two minutes after you enter the Thermometer Mode. The Thermometer Mode
indicator 1 flashes on the display during these two minutes.
After the first two minutes, the Thermometer Mode indicator 1 stops flashing,
and the watch automatically takes measurements every five minutes.
Understanding the temperature display
The display shows “– . °C (or °F) if a measured value falls outside the
range of 10.0°C to 60.0°C (14.0°F to 140.0°F). 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 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.
Calibrating the temperature
1. Use C to enter the Thermometer Mode.
2. Hold down A until OFF or the current temperature calibration value
flashes on the display.
OFF appears when the factory setting is currently set as the current
temperature calibration value.
3. Each press of D increases the displayed temperature by 0.1°C, while
pressing B decreases it. Holding down either button changes the value at
high speed.
If Fahrenheit is currently selected as the unit of measurement, the above
operations change the reading by 0.2°F.
Pressing B and D at the same time returns to the OFF setting.
4. After calibrating the temperature, press A to return to the Thermometer
Mode screen.
MEMORY
The watch is equipped with memory that you can use to store up to 10
barometric pressure, altitude, and temperature readings. Note that the date
and time of the measurement is not included with the data. The number of
available blank records that can be used to store data is shown on the right
side of the Barometer, Altimeter, and Thermometer Mode screens.
Storing a Measurement
While in the Barometer, Altimeter, or Thermometer Mode, hold down D for
about one second until the watch beeps, indicating that the latest
measurement is stored in memory.
The message FULL appears on the display for about one second when
you hold down D while memory is full. No more data can be stored while
memory is full.
If you want to store more data after memory becomes full, use the
procedure under Recall Mode below to delete the current data to make
room for new data.
