Barometer and Thermometer 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 official weather prediction or reporting applications.
• Sudden temperature changes can affect pressure sensor readings.
4. Press C to move the flashing between the temperature
value and barometric pressure value, to select the one
you want to calibrate.
• 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 all moisture from the case. It
takes approximately 20 to 30 minutes for the case of the watch to reach the actual
surrounding temperature.

• When mountain climbing, you can specify a reference altitude value in accordance
Altimeter
with a marker along the way or altitude information from a map. After that, the
altitude readings produced by the watch will be more accurate than they would
without a reference altitude value.
The watch displays altitude values based on air pressure readings taken by a built-in
pressure sensor.
How the Altimeter Measures Altitude
The altimeter can measure altitude based on its own preset values (initial default
method) or using a reference altitude specified by you.
To take an altimeter reading
1. Make sure the watch is in the Timekeeping Mode.
Current time
2. Press
D
to start Altimeter measurement.
When you measure altitude based on preset values
• ALTI will appear on the display, indicating that
Altimeter measurement is in progress. The first
reading will appear on the display after about four
or five seconds.
Data produced by the watch’s barometric pressure sensor is converted to approximate
altitude based on ISA (International Standard Atmosphere) conversion values stored
in watch memory.
• The current altitude value is displayed in units of 5
meters (20 feet).
• After the first reading is obtained, the watch continues
to take altimeter readings automatically every five
seconds for the first three minutes, and then every
two minutes after that.
When you measure altitude using a reference altitude specified by you
After you specify a reference altitude, the watch uses
B
that value to convert barometric pressure readings to
altitude (page E-34).

• If you leave the watch in the Altimeter Mode, it will update the displayed altitude
value regularly.
• Temperature is measured in the Barometer/Thermometer Mode and in the
Altimeter Mode. For details about temperature readings, see "Temperature"
(page E-24).
•
Normally, displayed altitude values are based on the watch’s preset conversion
values. You also can specify a reference altitude value, if you want. See “Specifying
a Reference Altitude Value” below.
• You can change the unit for displayed altitude values to either meters (m) or feet (ft).
See “To specify temperature, barometric pressure, and altitude units” (page E-39).
3. After you are finished using the Altimeter, press
Mode and stop auto measurement.
C
to return to the Timekeeping
Specifying a Reference Altitude Value
The altitude readings produced by this watch are subject to error caused by changes
in air pressure. Because of this, we recommend that you update the reference altitude
value whenever accurate altitude information is available during your climb. After you
specify a reference altitude value, the watch adjusts its air-pressure-to-altitude
conversion calculation accordingly.
• The watch will return to the Timekeeping Mode automatically if you do not perform
any operation for about 10 hours after entering the Altimeter Mode.
Note
• The measurement range for altitude is –700 to 10,000 meters (–2,300 to 32,800
feet).
• The displayed altitude value changes to - - - - if an altitude reading falls outside the
measurement range. An altitude value will reappear as soon as the altitude reading
is within the allowable range.
E-32
E-33
To specify a reference altitude value
How does the altimeter work?
1. In the Altimeter Mode, hold down A until the current
reference altitude value starts to flash. This is the
setting screen.
• Before the reference altitude value starts to flash,
the message SET Hold will appear on the display.
Keep A depressed until SET Hold disappears.
Generally, air pressure and temperature decrease as altitude increases. This watch
bases its altitude measurements on International Standard Atmosphere (ISA) values
stipulated by the International Civil Aviation Organization (ICAO). These values define
relationships between altitude, air pressure, and temperature.

Altimeter Precautions
Specifying Temperature, Barometric Pressure, and Altitude Units
• This watch estimates altitude based on air pressure. This means that altitude
readings for the same location may vary if air pressure changes.
• The semiconductor pressure sensor used by the watch for altitude measurements
is also affected by temperature. When taking altitude measurements, do not subject
the watch to temperature changes.
• Do not rely upon this watch for altitude measurements or perform button operations
while sky diving, hang gliding, or paragliding, while riding a gyrocopter, glider, or
any other aircraft, or while engaging in any other activity where there is the chance
of sudden altitude changes.
• Do not use this watch for measuring altitude in applications that demand
professional or industrial level precision.
• Remember that the air inside of a commercial aircraft is pressurized. Because of
this, the readings produced by this watch will not match the altitude readings
announced or indicated the flight crew.
Use the procedure below to specify the temperature, barometric pressure, and altitude
units to be used in the Barometer/Thermometer Mode and the Altimeter Mode.
Important!
When TYO (Tokyo) is selected as the Home City, the
altitude unit is set automatically to meters (m), the
barometric pressure unit to hectopascals (hPa), and the
temperature unit to Celsius (°C). These settings cannot
be changed.
To specify temperature, barometric pressure, and
altitude units
1. In the Timekeeping Mode, hold down A until the
currently selected city code starts to flash. This is the
city code setting screen.

• Before the city code starts to flash, the message SET Hold will appear on the
Precautions Concerning Simultaneous Measurement of Altitude and Temperature
display. Keep A depressed until SET Hold disappears and the city code
starts to flash.
Though you can perform altitude and temperature measurements at the same time,
you should remember that each of these measurements requires different conditions
for best results. With temperature measurement, it is best to remove the watch from
your wrist in order to eliminate the effects of body heat. In the case of altitude
measurement, on the other hand, it is better to leave the watch on your wrist, because
doing so keeps the watch at a constant temperature, which contributes to more
accurate altitude measurements.
2. Keep pressing C until TEMP (temperature), ALTI (altitude), or BARO (barometric
pressure) appears in the left corner of the screen.
• See step 3 under “To change the current time and date settings” (page E-18) for
information about how to scroll through setting screens.
3. Perform the operations below to specify the units you want.
• To give altitude measurement priority, leave the watch on your wrist or in any other
location where the temperature of the watch is kept constant.
To specify this unit: Press this key: To toggle between these settings:
• To give temperature measurement priority, remove the watch from your wrist and
allow it to hang freely from your bag or in another location where it is not exposed
to direct sunlight. Note that removing the watch from your wrist can affect pressure

• See step 3 under “To change the current time and date settings” (page E-18) for
information about how to scroll through setting screens.
Button Operation Tone
The button operation tone sounds any time you press one of the watch’s buttons. You
can turn the button operation tone on or off as desired.
• Even if you turn off the button operation tone, the alarm, Hourly Time Signal, and
Countdown Timer Mode alarm all operate normally.
3. Press D to toggle the illumination duration between three seconds (LT3 displayed)
and one second (LT1 displayed).
4. After the settings are the way you want, press A to exit the setting screen.
To turn the button operation tone on and off
1. In the Timekeeping Mode, hold down A until the
currently selected city code starts to flash. This is the
city code setting screen.
Illumination Precautions
• Illumination may be hard to see when viewed under direct sunlight.
• Illumination turns off automatically whenever an alarm sounds.
• Frequent use of illumination runs down the battery.
• The watch may emit an audible sound whenever the display is illuminated. This is
due to vibration of the EL panel used for illumination, and does not indicate
malfunction.
• Before the city code starts to flash, the message
SET Hold will appear on the display. Keep A
depressed until SET Hold disappears and the city
code starts to flash.

Troubleshooting
Time Setting
3. Press D to toggle the button operation tone between on
(KEY ) and off (MUTE).
■ The current time setting is off by hours.
Your Home City setting may be wrong (page E-14). Check your Home City setting and
correct it, if necessary.
4. After the settings are the way you want, press A to exit
the setting screen.
Mute indicator
■ The current time setting is off by one hour.
You may need to change your Home City’s standard time/daylight saving time (DST)
setting. Use the procedure under “To change the current time and date settings” (page
E-18) to change the standard time/daylight saving time (DST) setting.
Note
• The mute indicator is displayed in all modes when the
button operation tone is turned off.
Sensor modes
■ I can’t change the temperature, barometric pressure, and altitude units.
When TYO (Tokyo) is selected as the Home City, the altitude unit is set automatically
to meters (m), the barometric pressure unit to hectopascals (hPa), and the
temperature unit to Celsius (°C). These settings cannot be changed.

performed.
The battery indicator appears in the left corner of the digital
display whenever there is not enough battery power available to
perform a sensor operation in the Barometer/Thermometer Mode
or Altimeter Mode. Sensor operation is disabled while the battery
indicator is displayed.
Battery indicator
• Normal operation should return after battery power recovers.
■ “ERR” appears while a sensor operation is in progress.
Subjecting the watch to strong impact can cause sensor malfunction or improper
contact of internal circuitry. When this happens, ERR (error) will appear on the display
and sensor operations will be disabled.
•
•
If ERR appears while a measurement operation is being performed in a sensor mode,
restart the measurement. If ERR appears on the display again, it can mean there is
something wrong with the sensor.
Barometer/Thermometer Mode and Altimeter Mode sensor operations are disabled
whenever there is not enough battery power available to perform a sensor operation.
This is true regardless of the current battery level. In this case, ERR will appear on
the display. This does not indicate malfunction, and sensor operation should resume
once battery voltage returns to its normal level.
