Precautions for Use
This watch is not a measuring instrument authorized by official authorities. Do not use the altimetry function to judge situations involving danger. The following precautions should be adequately understood before using the altimeter. Please remember that the altimetry function should be used only as general reference.
(1) Do not Use the Altimetry Function When. . .
The altimeter should not be used in the following situations:
• When judging your actions or situation involving danger in an environment where the temperature changes drastically.
• In an environment where pressure is subject to change, such as in an airplane or building (correct measurement cannot be obtained).
• When the altitude changes greatly within a short time.
• In case of special handling other than normal use, not described in this manual.
(2) Altimetry Function
The altitude displayed by this watch is relative altitude based on the sensored air pressure and “The international standard atmospheric pressure and altitude”. Therefore, display of measured altitude will change if air pressure changes, even if measurement is made in the same place. The time delay from

English
Basic Functions of the Altimeter
This watch is designed to calculate altitude from changes in air pressure by using the relationship between air pressure and altitude, based on the conditions for standard atmosphere* specified by the International Civil Aviation Organization (ICAO). To obtain correct altitude on the watch, altitude must be aligned with an accurate point (triangulation station or benchmark). Such operation is called "altitude correction" (see page 12).
* Standard atmosphere: ICAO Standard Atmosphere adopted by the ICAO in 1964, whereby 1013.25 hPa at 15°C is
specified as elevation 0. However, air pressure continuously changes at any given place. This watch’s operating are based on ISA standards. The following chart provides an outline of ISA standard configurations. (from International Standard Atmospheric)
English
measurement to
display of altitude is approximately 5 seconds (in continuous altimetry mode). Therefore, this altimetry function may not be used in sports as sky diving, etc. where altitude changes greatly within a short time. After 30 minutes, Continuous Altimetry Mode will automatically change to Altimetry Mode in which measurement is made every hour. To resume Contin­uous Altimetry Mode, operate the watch as explained in the instruction manual. In order to efficiently use the altimetry function of this watch, the altitude must always be corrected for your location, clearly indicated with the altitude.
(3) Pressure Sensor
Do not disassemble the pressure sensor used in this watch or poke it with a thin rod. Take care that no dust enters the pressure sensor.
(4) Battery
The service life of the battery used in this watch is two years after loading a new battery with the watch used under normal conditions (see "Battery life" under "J. Product Specifications"). However, the service life depends on the conditions under which the functions are used. Thus, early replacement of the battery is recommended.

D. Altitude Compensation
[Altitude Compensation]
The altitude displayed by this watch is relative altitude based on standard atmosphere. To obtain the correct altitude during mountain climbing, the al­titude displayed by this watch must be aligned with an accurate altitude at a geographical point of reference (triangulation station, first-order benchmark, an altitude on an accurate map, etc.). Such an operation is called "altitude correction." If air pressure changes 1 hPa, the altitude difference will be approximately 10 m. Therefore, altitude compensation must be made several times a day if the weather changes drastically during mountain climbing.
English
3. Continuous Altimetry
The watch shows continuous changes in altitude once every 5 seconds for 30 minutes after the starting measurement for altitudes.
• Measuring the Altitudes Press button 2 once in Time Mode. The second hand changes to operate on an extended 2-second increments basis. This indicates that the watch is now in Continuous Altimetry Mode. Pressing button 2 once returns the watch to Altimeter Mode. Also, the watch will automatically return to Altimeter Mode 30 minutes after being set to Continuous Altimetry Mode even if no button is pressed.

Compensation
a) Press button for more than 2 seconds in Time Mode (or Continuous
Altimetry Mode). The second hand (G) changes to indicate 0.5-second increments. This indicates that the watch is now in Altitude Compensation Mode.
b) Press button or to correct the altitude.
• Button : Altitude Hand [I] (A) decrement up by 10 m in each time the button is pressed.
• Button : Altitude Hand [I] (A) increment by 10 m in each time the button is pressed.
c) After compensation is completed, return to Time Mode (or Continuous
Altimetry Mode). Pressing button for more than 2 seconds returns the watch to Time Mode (or Continuous Altimetry Mode).
Note: If the watch is left in Altitude Compensation Mode for more
than 1 minute it will automatically return to Time Mode (or Continuous Altimetry Mode. Auto Return)
