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
